Electromagnetic Flow Meter Working principles

Product Description:

An Electromagnetic Flow Meter is an instrument used to measure the flow of liquids, which is based on Faraday's law of electromagnetic induction and the Lorentz force principle.  The instrument consists of two parts: electromagnetic flow sensor and display controller.  

Electromagnetic flow sensors usually consist of an electromagnetic coil and a measuring electrode.  When the liquid passes through the sensor, the electromagnetic coil creates a strong magnetic field, and the conductive substance in the liquid (such as water or solution) creates an induced electromotive force.  By measuring the electrode, the velocity and flow rate of the liquid can be obtained.  

The display controller is the control center of the electromagnetic Flow Meter, which receives the signal from the sensor and converts it into a digital display of the velocity and flow rate.  The display controller can also provide additional functions such as alarm, data logging, and communication interfaces.  Our company's electromagnetic flowmeter, Precession Vortex Flowmeter, Thermal Gas Mass Flowmeter and other products are very high measurement accuracy, balance flowmeter, Nozzle Flowmeter are often used, our products are also very professional.

Product characteristics  :
 ★ Low frequency three-value rectangular wave constant current excitation, not affected by power frequency and various stray interference signals on site, stable and reliable performance.  
★ The new technology of non-uniform magnetic field and special magnetic circuit structure, the magnetic field is stable and reliable, and the volume is reduced, the weight is reduced, so that the flowmeter has the characteristics of small and lightweight.  
★ With automatic detection of air traffic control and circuit processing functions.  
★ The range can be modified online according to the actual needs of users.
