![]() Simply put, electromagnetic meters work by using an electromagnetic field to measure the velocity of a liquid passing through a channel. An electromotive force gives way for the electromagnetic induction produced through the electrical conductor in the magnetic field. When material and magnetic field move in relative to each other, voltage is created. The magnetic field produces electrical signals in the conductor. How Do Electromagnetic Flow Meters Work in Magnetic Field?Īccording to Faraday’s Law (Law of Electromagnetic Induction), the rate of conductive liquid passing through a pipeline is measured with electromagnetic flow meters with sensors. These mag meters are one of the most conventional measuring instruments available for measuring circulation rates because they use electromagnetic induction. It is a flow meter with no moving parts or obstructions.įluids require different metering systems because they come in different properties. The electromagnetic flow meters or magnetic or volumetric flow meters are instruments that have the ability to measure circulation rates of heterogeneous solutions, like dirty liquids, oil and water mixture, water-based liquids like raw material water, wastewater, water from reservoirs, liquids containing waste fluids, and/or intake water with a lot of dirt or garbage in it.Įlectromagnetic flow meters are devices used to measure flow, liquid velocity, and the rate of water moving through induced voltage. You must first be equipped with knowledge about this measuring instrument, and we will be helping by covering topics on how the electromagnetic flowmeters work, the different types available, and some of their common advantages.īy the end of this post, you should have a good understanding of whether this flow measurement is the right choice for you. They are used to measure linear, non-linear, volumetric flow, and the mass flow of fluid flowing through a channel but choosing the one right for you is another ball game entirely. It is important to note that several types of electromagnetic meters are available in the market today. This type of flow meter is useful? Electromagnetic flowmeters may be the perfect solution for you! This blog post will discuss everything you need to know about electromagnetic flow meters. ![]() If you have any questions or need any help selecting a flow meter, please contact us at or 1-80 to speak with an applications engineer.Do you need to measure the flow of liquids in your business but don’t know where to start? Do you need reliable flow measurements done regularly? If you answered yes to either of these questions, then you need to consider using an electromagnetic flow meter.Īn electromagnetic flow meter, also known as mag meter, is a device that uses Faraday’s law of induction to know the flow rate of the electrically conductive water body. If this is a process application, what is the size of the pipe?.Is the fluid chemically compatible with the flow meter wetted parts?.What is the minimum and maximum process temperature?.What is the minimum and maximum process pressure?.What is the minimum and maximum flow rate for the flow meter?.Do you require a local display on the flow meter or do you need an electronic signal output?.If the liquid is not water, what viscosity is the liquid?.Do you require rate measurement and/or totalization from the flow meter?.What is the fluid being measured by the flow meter(s) (air, water, etc…)?.Therefore, time should be invested in fully evaluating the nature of the process The basis of good flow meter selection is a clear understanding of the requirements of the particular application. They are also ideal for applications where low pressure drop and low maintenance Magmeters will generally not work with hydrocarbons, distilled water and many non-aqueous solutions. A conducting fluid and a non-conducting pipe linerĪre required. Electrodes detect the voltage which is directly proportional to the flow rate.Įlectromagnetic flow meters can measure corrosive liquids and slurries, and have the ability to measure flow in both directions with equal accuracy. ![]() Is created by energized coils outside the flow tube. ![]() With magmeters, the liquid serves as the conductor and the magnetic field According to Faraday's Law, the voltage inducedĪcross any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor. Flow Meter Resources Flow Meter Application AdvisorĮlectromagnetic flow meters are volumetric flow meters that measure the voltage created when conductive liquids move through a magnetic field.
