How do electromagnetic flow meters work

2022-04-12

Electromagnetic flowmeter (Eletromagnetic Flowmeters, referred to as EMF) is a new type of flow measuring instrument developed rapidly with the development of electronic technology in the 1950s and 1960s. The electromagnetic flowmeter is made according to Faraday's law of electromagnetic induction, and the electromagnetic flowmeter is used to measure the volume flow of conductive liquids. Due to its unique advantages, electromagnetic flowmeters have been widely used in the flow measurement of various conductive liquids in industrial processes, such as various acids, alkalis, salts and other corrosive media; electromagnetic flowmeters for various slurry flow measurement, forming unique application areas.

Structurally, an electromagnetic flowmeter consists of an electromagnetic flow sensor and a converter. The sensor is installed on the industrial process pipeline. Its function is to linearly transform the liquid volume flow value flowing into the pipeline into an induced potential signal, and send this signal to the converter through the transmission line. The converter is installed not too far from the sensor, it amplifies the flow signal sent by the sensor, and converts it into a standard electrical signal output proportional to the flow signal for display, accumulation and adjustment control.

WESDOM has been producing electromagnetic flowmeters for many years. If you have any questions about electromagnetic flowmeters, you can feel free to contact WESDOM staff and we will help you solve the problem.
