How to Pick and Buy a Digital Flow Meter for Oil and Other Liquids

Flow meters are technological instruments used to measure the flow of liquids and gases in pipes, whether in linear or non-linear, mass or volumetric readings. The digital flow meter has many applications across different industries, from mining, to marine, water management, food processing, power and energy conservation, agriculture, pharmaceuticals, building services and construction, petrochemicals, to even the aerospace industry.

Today’s flow meters come in various forms and sizes, with many practical and highly effective features that have essentially made the instrument more accurate and reliable.

Selecting a Suitable Digital Flow Meter for Oil and Other Liquids

One of the most crucial elements you need to consider when buying either a handheld or fixed installation flow meter is the specific purpose or the application of the instrument. The installation process has to be considered as well, and whether or not you want a handheld/portable device for mobility or just a conventional flow meter that can be installed in a specific area.

There are varying reasons why one will go for the handheld and why the other will opt for the fixed installation flow meter. If you work as an HVAC specialist, for example, then you might prefer the handheld device. But, if you run a food processing business, then a fixed installation flow meter would be a more practical choice.

Here are some of the elements you need to think about, in addition to the installation process:

  • What type of fluid do you want to measure? Does it have the same consistency as slurry or does it flow like water?
  • What is the viscosity or thickness of the fluid? Is it filled with fine particles or is it clean with minimal particulates?
  • You should also consider the size of the pipe the liquid flows through, as well as the type of material the pipe is made from.
  • What kind of reading output are you interested in?
  • What type of information do you want to obtain from the instrument; flow rate, total volume, or both?
  • For wetted flow meters, you need to consider the chemical compatibility of the instrument’s parts and the liquid being measured.
  • Liquid flow rate, volume, and pressure must also be considered.

The Different Types of Flow Meters Available in the Market

By looking at those different considerations, you get an idea of how diverse the flow meter industry is, not just in the design, application, and materials used to produce the instrument, but in the technology that goes in the device as well. Here are some of the common flow meter types found in the market, regardless of whether they’re designed to measure gas, liquid, or some other substance:

  • Ultrasonic flow meters
  • Magnetic flow meters
  • Spring and piston meters
  • Paddle wheel sensors
  • Positive displacement (PD) flow meters
  • Mass gas flow meters
  • Turbine flow meters
  • Vortex flow meters
  • Variable are flow meters

When buying a suitable flow meter, you need to make sure it has all the specific requirements that you’re looking for and the features that you need for your specific needs.

A Quick Guide to Choosing a Digital Flow Meter

Flow meters are important to various industries because they help determine the amount of gas, liquid, or vapor present in a particular area. If you plan to get one for whatever purpose, you’ll have to make sure you choose the right type of digital flow meter and that the device you get is of top quality. Never make the mistake of choosing based on price alone and then trying to justify your choice with the amount of money you saved with the purchase.

In choosing a flow meter, you’ll need to take a number of factors into consideration, including the ease of calibration and maintenance, durability, accuracy of reading, the credibility/track record of the manufacturer, and the availability of spare parts. The cost of the device should only be considered once all of the other important considerations have been taken into account.

Choosing the Right Digital Flow Meter

How do you make sure that the flow meter you get is the right one? The first thing you need to do is determine whether you need the flowrate information to be totalized or continuous. You also need to decide if you will only be getting the information locally or if you need to get it remotely as well. If the information needs to be gathered remotely, you’ll have to determine whether it will be best transmitted via analog, digital, or shared means. If you go for shared transmission, you’ll have to determine the minimum required data-update frequency.

When you have all of these data on hand, can you already consider yourself ready to start shopping for a flow meter? Not quite. There is still a second phase you need to go through in order to be absolutely sure you won’t be wasting your money on the wrong device. This second phase involves evaluating the flow characteristics and properties of the process fluid as well as the piping to be used for your flow meter.

Where the process fluid is concerned, there are things like temperature, pressure, allowable pressure drop, specific gravity, viscosity, conductivity, and vapor pressure at the maximum operating temperature to consider. The manner in which all of these properties are likely to interact and/or vary also has to be determined and indicated, along with safety and toxicity information as well as detailed information on the composition of the fluid. Data on the possible presence of solids and bubbles in the process fluid, a possible tendency to coat, and its light transmission qualities should also be provided.

In the case of the piping and the area where your flow meter will be located, the following factors will have to be considered: the direction of the piping (a downward flow will have to be avoided for liquid applications), the size of the pipes, the piping material, the flange pressure rating, the area’s accessibility, upstream and downstream turns, regulators, valves, and straight-pipe run lengths.

Of course, you don’t have to make all these determinations yourself, unless you really are familiar with the process. You can hire the services of a professional engineer who can assist you not only in the planning and preparation, but even in choosing the right flow meter and in the installation process. The engineer will also be responsible for determining whether there are vibrations or magnetic fields in the area, if the area has been classified for explosion hazards, if pneumatic or electric power is available in the area, and if there are any special requirements you need to fulfill prior to installation.

The third phase in ensuring that you get the right flow meter involves determining the necessary meter range. This is done by identifying what the minimum and maximum flows to be measured are (mass or volumetric?). You then need to determine what the necessary flow measurement is. Make sure your accuracy requirements are stated at the normal, minimum, and maximum flowrates. All of these requirements are important because they help you ensure that the performance of your flow meter is acceptable through its full range.

Key Questions

As a recap of what you need to do in order to make sure the flow meter you get is the right one for your needs, here are the key questions you need to ask before you go out to shop for a flow meter:

  1. What kind of fluid are you planning to measure?
  2. Will you be doing rate measurement or totalization measurement?
  3. If you plan to measure liquid other than water, what is the viscosity of the liquid you’ll be measuring?
  4. Will a local measurement display on the flow meter be enough for your purposes or will you require an electronic signal output?
  5. What are the minimum and the maximum flow rate?
  6. What are the minimum and the maximum process pressure?
  7. What are the minimum and the maximum process temperature?
  8. Is the process fluid chemically compatible with the wetted parts of the flow meter?
  9. If what you’re planning is a process application, how big is the pipe?

The answers to these questions will make it a lot easier for you to determine which particular flow meter you should get.

Installation Cautions

It’s not enough for you to make sure you buy the right flow meter; you should also make sure it is installed properly so that it functions exactly as it should. For one thing, you have to make sure that a flow meter used for liquid service remains full of liquid while it is installed because any amount of gas or vapor in it can change its geometry and negatively affect the meter’s accuracy. For flow meters to be used in gas/vapor service, the opposite is true: it has to remain full of gas/vapor because the presence of moisture or liquid can alter its geometry.

Note as well that any disturbance such as control valves and pipe elbows can also affect reading accuracy, so it is best to place them downstream, so the disturbance in the flow will not be reflected by the flow meter measurement.

Finally a Headset That Perks You Up!

People love getting a fix. It’s practically the reason why alcohol and caffeine are among the world’s most heavily consumed commodities. Nowadays, you can get the same kind of fix from a mood-changing headset known as the Thync.

With the use of electrodes, this simple device can easily lift your mood up. It can produce the same energizing effect when you drink a cup of coffee as well as the same relaxing or calming effect when you down an alcoholic drink.

The device was developed by a startup company based in Silicon Valley. According to its CEO, Isy Goldwater, she imagines people wearing the mood-changing headset to help them obtain a caffeine-free pick me up or simply to unwind after a long tiring day. “We are giving people a way to overcome a basic limitation—that no one is really wired to co-opt energy and calm on demand.” He says.

The idea behind the Thync is undeniably amazing. After all, who wouldn’t want to be able to feel good in an instant? However, the device may not work for everyone. This is due to the reason that people are not built the same way. About a third of the world’s population just don’t have a strong response. Some people may only feel a tingling when the device starts to make contact with their skin but feel no sense of serenity even after several sessions.

Nonetheless, it would be a great device for people who can actually feel a response. Basically, the headset employs tDCS or transcranial direct current stimulation. This allows the Thync to maintain and deliver a constant low current to the user’s head through a surge of electrodes. As an end result, the electrodes change the activity of neurons in a particular area in the brain. According to studies, this type of approach can help improve a number of cognitive abilities. Due to its range of potential uses, neuroscientists are currently experimenting on its application in the medical field.

Thync is currently the only device aimed to alter the state of mind of healthy people. As mentioned, it uses electric waveforms to target specific cranial nerves to change a person’s mood. When used in a 10-minutes session, the effects of the device can last for up to 45 minutes. As of now, the headset can be operated through a smartphone. With the application installed in the smartphone, the user can control the amount of current as well as the strength of the effect.

The device has been tested on more than 3,000 people. In addition, the company has also funded a study by the City College of New York involving 100 people to test the calming effect of the device. Although the effects varied from one individual to another, the tests showed that the device had indeed improved the user’s mood. “To their credit they have engineered something that, at least in this situation, produced a bigger change,” says Marom Bikson, the biomedical engineering professor who led the study.

To counter the safety concerns involving cognitive enhancing devices, the Thync will only be made available for adults.

The Moisture Analyzer: What It Is and How It Works

Before delving into the different types of moisture analyzers, what they are, and how they work, one has to first understand the process of moisture analysis. Analyzing moisture content in any given item, whether it be high level or trace amounts of gases, solids, or liquids, covers a wide range of methods. Measurement of trace moisture is important in a variety of applications, such as in process quality assurance and marketing.

Trace moisture measurements in solids like pharmaceuticals, plastic, heat treatment processes and the like must be done to control moisture content and maintain quality. For liquid or gas products, moisture measurement applications for moisture are hydrocarbon processing, dry air, bulk pure gases, pure semiconductor gases, natural gas pipeline transport, and dielectric gases like what is found in transformers and in power plants.

Chiropractic Care – Does It Work for Allergies?

Whenever spring comes around, people are usually filled with excitement because it usually means better weather, plants growing, and flowers blooming. But if you’re prone to allergies, springtime can be tough because it can mean bouts of sneezing and coughing due to the increased amounts of pollen in the air. The phrase “spring is in the air” definitely does NOT have a happy connotation for those with allergies.

But we have good news for you! There may be a way to change how your body reacts to common allergens and how you generally feel about springtime. There may be a way for you to finally be able to say, “Spring is in the air!” with a huge smile on your face.

Allergies and Chiropractic Care

Chiropractic care is now being recommended by an increasing number of people for getting relief from allergies as well as for preventing allergic reactions. Chiropractic care does not involve any medication, and it does not involve surgery of any kind. It is an alternative healthcare system that is focused on ensuring the proper function of your nervous system.

How does this affect your allergies? Well, when your nervous system works the way it was designed to work, your immune system is effectively strengthened. This helps prevent allergic reactions. And if you are already suffering from allergies, the chiropractic techniques used by your chiropractor will be targeted towards restoring your body’s healthy functions such that it can gradually heal itself, thereby relieving you of your allergies.

The concept behind chiropractic is that the human body is perfectly capable of healing itself as long as all of its systems are functioning properly. This is why the focus is to correct any misalignment in the musculoskeletal system (which affects practically your entire body) and disruption in the nervous system (which serves as the main communication line between your brain and all your other organs). If your nervous system and musculoskeletal system are working properly, your body is pretty much in great shape and can heal itself.

Although there is still a lack of research and scientific studies into chiropractic as an alternative healthcare system, the amount of anecdotal evidence of its effectiveness is significant and continues to grow exponentially. This is why the number of people seeking chiropractic treatment for allergies and other physical complaints is continuously increasing. So if you’re seeking relief from those bothersome allergy symptoms, you may want to consider getting chiropractic treatment. At the very least, it may be a good idea to consult a chiropractor regarding your allergies.

Of course, just like traditional medicine, chiropractic treatment does not work for ALL allergy cases. But it has been shown to work for many. The degree of effectiveness of any treatment method will depend on the root cause of the problem, and this is why it is important for you to talk to healthcare professionals first before deciding if this particular healthcare system is the right one for you. Getting your body in top condition is the best way to enjoy a full life, and chiropractic may just be the solution you’re looking for.

Basic Things You Need to Know about Your Cat

As far back as we can remember, cats have been popular household pets, giving owners the perfect companion to take care of every single day. However, while they are cute and playful to have around, let’s not forget that they are like human beings that need constant love, care, and attention.

They Don’t Want to Be Disturbed

Cats are known for their habit of sleeping for most of the day and like human beings, they do not wish to be disturbed. They are crepuscular creatures, meaning they are more active during the twilight hours. Kittens are also more active during the night.

There Are Parts of Their Bodies That They Don’t Want Touched

Like human beings, these furry creatures have spots that they do not wish to be touched. It’s best that you shouldn’t touch them in these areas (e.g. their tummies, behind their eyes, tails, etc) for they’ll surely take a swipe at you; you might even get bitten.

Cats Are Moody

Like women during their monthly period, a cat’s mood is mercurial. So don’t push them away like your dirty laundry if they want you to pet them. That’s just how they really are.

They Love to Scratch Things

Our lovable feline friends love to scratch their claws on almost anything—from furniture to even your favorite pair of jeans. Cats usually do this because it’s their way of keeping their claws sharpened (it’s also a way of exercise for them). As much as we don’t wish to get our household items torn or damaged, cats need to do this to keep their claws in good condition. Having scratch posts would minimize this problem.

With all these things mentioned, we hope this will help you get to know more about your pet cats and how to take care of them.

Surefire Strategies for Hiring the Best Software Developers

In today’s highly advanced society, technology is in demand. Anybody who has knowledge and experience in technology is considered an asset—to a company, an organization, to a community. Practically everybody wants a techie, which is why you need to know how to stay ahead of the pack if you want to hire the best technology experts.

If you want to attract the best software developers, you have to do more than look good and talk about how long your company has been in business. There are specific attributes that software developers look for. No worries, though, because you can always take advantage of several strategies to attract the right kind of tech talent for your company.

Strategies for Attracting the Right Software Developer

Make sure you have a strong brand. Software developers will not only look at a company’s background, they will also consider the brand. What kind of image does your brand project? What can your brand offer the best software developer? How strong is your brand? What makes it different from other brands in the industry?

These are the questions you need some answers to. Ask yourself these questions and if you get good, attractive answers, your company won’t have a difficult time getting software developers to knock on your door.

Do some research and find out where the best talents are. To gain access to the best software developers, you have to know where to look for them. It can be all about a specific place, or it can be an organization or talent pool. What you need to watch out for is the level of demand in particular areas. If the demand is high in, for example, New York, you are going to have a hard time looking for one. Look a place where the demand is not that high.

Once you have established contact with your prospects, it’s time for the interview. Interviewing prospective team members is the best way to find out if you have made the right choice. Of course, you should have at least three or four developers in the lineup to make sure you find the ideal one.

The interview is where you get to know more about the developer. As such, it is important to ask the right questions. First of all, you will want a developer who understands what your business goals are. In addition, your ideal software developer should be flexible and can work on one project after the other. A developer who knows how to relay information about complicated issues or ideas in the simplest terms is also a good one.

Develop your interview questions with these questions in mind, so you will be able to determine which candidate should be taken in by the company.

As it is inevitable, prepare to answer some questions fielded by your prospective developers.  You have to remember that these developers are being wooed by not just one or two, but multiple companies. Your answers to their questions should help paint an impressive image of the company. Of course, you should back up your answers with facts. Telling the truth is the number one rule.

Leave a positive impression on your candidates and you’ll have them jumping up and down with excitement.

Show developers what their future will be like if they choose your company. Stability, not just in financial terms, is an important matter for candidates. Therefore, you should be able to show your prospects a clear idea of what their future will be like in the company. If your company offers stock ownership options or fast career advancement, let your candidates know. It will also help if you mention opportunities for career development while employed in your company.

Build a good team by asking for referrals. If your intention is to build a pool of good software developers, your first step to fulfilling this goal is finding referrals. Where can you get them? From your newly hired developer!

If your new software developer is a treasure, it’s almost always a guarantee that he or she knows people who are as good as he or she is. So, ask for referrals. To make it more interesting, develop a program that will reward employees or team members who can refer good candidates for the position.

To make all these strategies work, it is important that you understand your company’s needs. Why do you need software developers? What are the goals you wish to achieve by hiring a developer? What other factors can developers contribute to your company? Most important of all, you need to understand what your company can offer and what it stands for.

Once you know all these, you will be able to come up with a good program for software developers, which you can then use to attract the best ones to your company or team.

Chiropractic Care – 5 Common Techniques

As chiropractic care gains popularity among patients, an increasing number of people want to learn more about it. Allow us to help you gain a better understanding of what kind of healthcare system chiropractic is and how it can benefit you.

What Is Chiropractic?

Chiropractic is a healthcare system that focuses on the proper alignment and function of the human body’s underlying structure, particularly the skeleton, and joints. Chiropractic doctors treat medical conditions under the premise that any pain a patient experiences results from problems in their musculoskeletal and nervous systems. This means that if you are suffering from back pain, neck pain, or headaches, you are most likely exhibiting the symptoms of a misalignment in your skeleton or inflammation in your muscles and joints, which disrupts the natural flow of your body.

There are over a hundred different techniques used in chiropractic, but there are just about ten that are most commonly used by chiropractors. To give you an idea of what the most common chiropractic techniques are, here is a quick overview:

1. Direct Thrust

This technique is what most people mean when they talk about spinal manipulation. It is the most well-known and widely-used chiropractic technique. This is the technique that typically causes that cracking sound many people are worried about, but is actually just the result of air released from between the joints.

2. Articulatory

This technique targets injured joints, with the goal of restoring your full range of motion in those joints. The goal is achieve through the careful application of force as the affected joints are moved through their normal range of motion.

3. Muscle Energy Technique

This chiropractic technique requires the patient’s participation. It targets stiff areas in your body that cause pain. The idea is for the patient to move specific parts of his body. While he does that, the chiropractor will apply counterpressure. This is done until the full range of motion of the affected area has been targeted.

4. Cervical Spine Manipulation

The cervical spine is the part of the spine where your neck is. Problems in this area can lead to upper back pain, discomfort in the upper arms and shoulders, headaches, and a reduced range of motion in the shoulders and neck. This technique is targeted towards eliminating the problem with the use of the same basic techniques used in direct thrust.

5. Functional Technique

This technique targets restricted joints. The purpose of the technique is to improve overall mobility by removing the restriction. In using this technique, the chiropractor gently moves the affected joint through its normal range of motion. When he detects a restriction, he will hold the joint at that point and apply gentle pressure until the restriction is released.

When you consult a chiropractor, it is best to ask about the technique he plans to use in your case. A deeper understanding of the chiropractic technique to be applied goes a long way towards easing any apprehension you may have regarding this alternative form of treatment.

Top Free Computer Software You Might Find Useful

Have you ever heard the saying “the best things in life are free”? Well, that may be true but consumerism has certainly made it a lot tougher to believe in this day and age. Fortunately though, in the world of computer applications and software, there might be a hint of truth to the adage. There are indeed quite a few computer software programs out there that are not only useful and topnotch, but are available for free as well. Here are some of them.

If you’re looking for free office suite utilities:

  • Apache OpenOffice – This particular productivity suite is free and open source. It is a good alternative to Microsoft Office, even at the professional level. It has the functionality and a lot of the basic features generally found in Microsoft’s productivity software.
  • AbiWord – This is a free word processing tool that is comparable to the much more well known Microsoft Word. It is lightweight and works well for a wide range of word processing tasks.
  • Jarte – Another word processing utility that is based not on the Microsoft Word, but on the word processing engine that’s built into the Windows OS, the Microsoft WordPad. It’s light, portable, and can do so much more than the WordPad in terms of features.

If you’re looking for free system optimization and diagnostic tools:

  • CCleaner – This is a system optimization utility, as well as a privacy tool that enables the user to remove unused files safely from his system. Because it can free up valuable disk space and optimize the system, Windows can run much faster and more efficiently.
  • Process Explorer – This particular software is an advanced process management tool that works very much like the Task Manager in your Windows PC. The key difference, however, is that it can show more comprehensive information about any given process, from the memory statistics to the security attributes.
  • SmartDefrag – Although your Windows system already has a built-in defragmenting tool, this particular software is actually something more special. SmartDefrag is a lightweight defragmenting tool that features an advanced system checker that continually defrags frequently used files in the background, without slowing down your system resources.

If you’re looking for free virtual server software:

  • OpenVPN – This is a tried and tested open source VPN solution. This software is completely secure and offers almost an infinite number of configurations. It can easily be installed without relying on third party services.
  • VMware Server – This is a free, user-friendly server virtualization software. It can be installed on any existing server hardware that runs either on Windows or Linux. VMware can also partition any physical server into multiple virtual machines. By condensing the network, memory, storage, and processing resource, you will have better hardware utilization and flexibility.

LogMeIn Hamachi – This is a hosted VPN service that provides a secure LAN-like network extensions for various teams. Through this particular service, you can create your own virtual private network in mere minutes. With Hamachi, you can securely and easily access your PC at home from your office, or vice versa. A very useful tool, especially if you “live in your computer.”
