The measuring principle of the electric flowmeter is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a short non - conductive alloy tube lined with insulating material. Two electrodes are fixed on the measuring tube along the diameter through the tube wall. The electrode head is basically flush with the inner surface of the lining. When the excitation coil is pulsed by two waves, a working magnetic field with a flux density of B will be generated in the direction perpendicular to the axis of the measuring tube. At this point, if a fluid with a certain conductivity passes through the measuring tube. The cut magnetic line of force is induced to generate electromotive force E. The electromotive force E is proportional to the product of the magnetic flux density B, the inner diameter of the measuring tube d and the average velocity v. The electromotive force E (flow signal) is detected by the electrode and sent to the converter through the cable. After the converter amplifies the flow signal, the fluid flow can be displayed, and the output pulse, analog current and other signals can be used for flow control and regulation.

GM all-intelligent electromagnetic flowmeter is developed with advanced technology at home and abroad. The core adopts high-speed central processing unit (CPU), equipped with backlit wide-temperature Chinese and English liquid crystal display, with complete functions and easy operation. The unique multi-electrode structure further ensures the accuracy and stability of measurement, can meet the field conditions without grounding ring, reduce the workload of installation and maintenance. In the service life, appearance, reliability, stability, measurement accuracy and other aspects are much more advanced than the old analog or non-intelligent electromagnetic flowmeter.
