What is an electromagnetic flowmeter?
Electromagnetic flowmeter, also known as electromagnetic flowmeter or electromagnetic flowmeter, is a volumetric flowmeter. The electromagnetic flowmeter does not have any moving parts, so no maintenance or replacement is required. In a wide flow range, the accuracy can reach ±0.5% or higher of the flow.
The electromagnetic flowmeter adopts barrier-free design, eliminating the flow barrier. It works with electrodes embedded on opposite sides of the flow tube or sensor to pick up the signal. Electromagnetic flow meters perform well in many municipal and processing applications, and have become the instrument of choice for measuring conductive liquids.
How does the electromagnetic flowmeter work?
All electromagnetic flowmeters operate according to Faraday's law of electromagnetic induction to measure liquid velocity. The working principle shows that a conductor passing through a magnetic field generates an electrical signal in the conductor, which is proportional to the speed of water passing through the magnetic field. Essentially, when a fluid flows through a magnetic field, the conductive particles in the fluid produce a voltage change in the magnetic field. This change is used to measure and calculate the velocity of water flowing through the pipeline.
Advantages of using electromagnetic flowmeter
The main advantages of using electromagnetic flowmeters are that they require less maintenance and can order very large pipelines. Some can be installed by simple hot taps without shutting down the production line. Electromagnetic flowmeters also have the benefit of increasing consumer trust: they hold service providers accountable for the water actually produced and/or billed. These efforts will help protect our water resources while improving the profitability of utilities.
Electromagnetic flowmeters are usually the first choice when measuring water-based conductive liquids. It has the advantages of low cost, accuracy and long life.
