How Magnetic Flow Meters Work

Friday, June 24th, 2016

A magnetic flow meter is technically referred to as an electromagnetic flow meter. These are the third most common type of flow meters.
The other two meters that are more common than the magnetic type are the positive displacement and differential pressure flow meters.

Commonly, the magnetic meter is known as a mag meter. These types of meters operate according to Faraday’s law of electromagnetic induction. According to Faraday’s law, as the conductor moves through the magnetic field the voltage is induced. The liquid flowing through the magnetic field serves as the conductor.As for the magnetic field that is created through energized coils that are located on the outside of the flow tube. When it comes to the selection of magnetic flow meters, certain considerations are necessary. This entails things such as the mounting type, pipe diameter, end fittings, performance specifications, special features, and output options. Other important considerations are the ability to monitor media temperature and meter liquids with suspended solids.

In general, these types of meters differ in accordance to their mounting type and pipe diameter. The available options for mounting are the non-invasive, insertion type, and in-line. As for the pipe diameter, this refers to the process pipe, which is going to be monitored.An in-line flow meter is directly installed within the process line. Usually, in order for this type of installation to take place it must be installed on a straight pipe. On the other hand, the insertion-type devices do not have to be installed on a straight line of a pipe.

In most cases, the insertion-type devices require a threaded hole within the process pipe. As for the non-invasive electromagnetic flow meters, they do not have a requirement for direct-mounting within the process flow. Additionally, they can be used within the closed piping systems. Types of magnetic flow meter end fittings
* Clamp
* Compression
* Flanged
* Plain End
* Socket Weld
* Union
* Threaded
* Tube End
* Hose Nipple
The external clamp-on flow meters are non-invasive and use compression fittings in order to tighten them over a joint so they do not leak. In most cases, flanges are square or circular and are connected by welding or bolting. As for the plain-end devices, they can be inserted into the end of the connecting pipe.

The interface and electrical output are the two types of options for magnetic flow meters. The available options for electrical output are switch output, frequency, analog voltage and current. The options available for the interface are fieldbus, network, digital, and serial.

In most cases, a National pipe thread (NPT) is used with threaded designs. Generally, hose-nipple fittings or tube-end fittings are used with shorter pieces of pipe that are male threaded. Magnetic flow meters differ in relation to their features. Some of them have the capacity to measure temperature, level, or density and may have features such as visual or audible alarms, in addition to other types of features. Magnetic flow meters are also available for sanitary applications as well.

Different types of Flow Meters

Monday, April 25th, 2016

A flow meter is definitely an instrument which can be used to measure the flow of fluid.The Fairest anesthesia machine flow meter Are Delivered, Go to Have a Look!. It’s a broad array of industrial makes use of. Along with a number of stream meters have emerged because the industry continues to develop. With a large number of different styles of movement meters, it truly is really required to classify the stream meters, so that men and women will get to know which kind of flow meter to pick in several functions.Several Beauty and Wrong-doings of oxygen flow meter. There’s two methods frequently used in classification, the 1st one particular is usually to classify through the measurement principle in the flow meters, the second a single is as per the structure with the stream meter. Below we’ll mostly talk about your second a single, for it can be more clarity.


Based on the real circulation goods in latest along with the construction principle, the stream meters can be broadly grouped into the subsequent types. Volumetric flow meter Volumetric circulation meter is equal into a regular quantity of container, which keeps measuring the circulation medium. The theory of the volumetric stream meter is simple, and it does very effectively in measuring these fluids with high viscosity and low Reynolds amount. Impeller-type movement meter The impeller is positioned in the measured fluid, and also the impeller will rotate when the fluid flow. The size with the very low is measured through the rotating speed of the impeller. A single case in point of the sort of circulation meter is the turbine circulation meter, the output of it can be electrical pulse signal, and it’s higher accuracy. Differential pressure flow meter This sort of system contains the first product and the second system.


The first product is called stream measurement gadgets, it’s installed in the fluid pipeline, and the pressure distinction will likely be generated, your second device will display it. The 2nd gadget is really a display product, it receives the differential stress sign produced by the very first product, and rework it into your corresponding flow, then show it. This strategy for movement measuring incorporates a prolonged history, could it be much more mature then other styles of movement meters. And this sort of circulation meter can typically be noticed in electricity plant, measuring the stream of steam, feed drinking water and condensation h2o. Variable location circulation meter It is also known as stress decline movement meter. One standard case in point of this kind may be the rotor circulation meter. Momentum flow meter The dimensions with the circulation is measured by measuring the momentum in the fluid. Focus on movement meter and rotating wing plate kind floe meter belong to this sort. Impulse-type circulation meter It truly is usually utilised to evaluate the circulation of granular solids, slurry, abrasive and other liquid and crystalline stream. The measuring array is from a number of kilograms every hour to nearly thousand tons every hour. Electromagnetic circulation meter Accuracy and sensitivity of the measuring outcomes are quite often higher. It can be typically used to evaluate the circulation of h2o, pulp and also of media. However, it cannot be employed to measure these press with minimal conductive, this sort of as gas, steam, and so forth. The cost of electromagnetic movement meter is a little higher, and also the signal is susceptible to external magnetic interference, that is certainly why this sort of circulation meter isn’t so broadly utilised in industrial control apps. Ultrasonic flow meter Ultrasonic stream meter is a non-contact measuring instrument, it can be frequently utilised in the event the circulation is uneasy to access or is hard to observe.


The dimensions in the circulation can also be reflected while in the results of stream speed measuring. Oscillating fluid circulation meter Since it does not have rotating elements as well as the output is digital pulse, this sort of movement meter is extremely promising. Presently, vortex circulation meter is broadly used. Mass movement meter As being the volume of fluid is definitely afflicted by temperature, stress along with parameters, the medium parameters are required when utilizing quantity to show the size of circulation. But in the functions if the medium parameters keep changing, it is quite difficult to fulfill this requirement, subsequently the shown price won’t be appropriate. In this instance, a mass movement meter is required. These ten types of flow meters just isn’t the finish of movement meters. Together with the development of technologies, an increasing number of new kinds of stream meters will emerge to apply in variable occasions.

Some other types of units will also do the monitoring and periodic testing automatically. The electrician or engineer can set the times for the testing and set different alert displays for safety.

A device can be used to monitor tenant metering, substation automation, utility submetering and generator monitoring. A lot of utility companies such as the electric company use automated metering reading equipment to measure, manage and record electrical usage. Most are multifunctional and very efficient.

Another important factor when considering the type or make and model of the transducer or meter is the type of protocol it will use. There are several types of protocols that help to advance communications capabilities. These protocols are Modbus Plus, Modbus RTU and ASCII, and DNP 3.0.

The amounts of different electrical outputs are important when considering which electrical testing equipment. It is important to know how many electrical parameters are being measured. Always make sure that all of the necessary power functions are being monitored and tested on a regular basis.

If for any reason the customer is not comfortable with installing, testing or monitoring electrical function of any type, then a professional electrician or technician should be contacted. A professional electrician with the proper certifications will know what to do should something go wrong with the installation or testing process. Monitoring voltage, watts, VARs, volts and other variables is extremely important when working around electricity.

Compressed Air Flow Meters: A Reliable Solution for Mitigating Compressed Air Leakage

Wednesday, April 15th, 2015

Air, which is consecutively kept under a unwavering pressure, normally higher than the atmospheric pressure, is known as compressed air. The worth noticing fact which makes this naturally available substance as precious as diamonds is that few percentile of compressed air could generate power and energy up to hundreds of terawatt every hour and this is the reason why industries have started relying on using compressed air flow meters that are engineered to regulate the every unit all the time.

Every one of us must have seen an instrument or equipment that uses compressed air and those could be using a gas duster, airbrakes, oxygen gas cylinders used by deep-sea divers, in air guns, jackhammers, tire inflaming pumps and pneumatic devices. Its beneficial attributes makes it distinctive from other source of utilities, such as its capability to supply a motive force in a safer and more convenient manner. The compressed air’s instruments like screwdrivers, drill machines, sprinkler systems and many more are reducing the requirement of human force and are becoming a reason for increased productivity and profit generation.

Undoubtedly, there are some health hazards attached to these instruments that could turn any favourable situation into an unknown havoc. A blast in the equipment, due to irregular flow of air or disturbed flow of compression (generally under 40 psi), could cause brain damage or an explosion near mouth is competent enough of rupturing lungs. These catastrophes can be avoided by using the cited compressed air flow meters to regulate and monitor the supply.

As far as business hazards are concerned, those cannot be overlooked too. As this source of energy is very precious and expensive, hence leakages and loss of air is strictly unbearable and requires a constant surveillance of technicians. In addition to these, there are certain production processes that require specific airflow during various processes and any malfunction would lead to disrupt all the stages in a production process. Moreover, any wastage or leakages will affect a business’s manufacturing account, profit and loss accounts or balance sheet and could become a stain on management decisions. In such cases, implying an air flow meter is a wiser option instead of paying extra dollars as penalties.
