LDG-B050 clamp connection integrated type electromagnetic flowmeter [CHENGFENG FLOWMETER] PTFE lining stainless steel electrode
Product Model:LDG-B050

 

CHENGFENG FLOWMETER intelligent electromagnetic flowmeter is based on a standard manufacturing system and development, its advanced design concepts to ensure the high precision and high reliability of the product, compared with the old electromagnetic flowmeter, it has high measurement precision, high reliability, good stability, complete function, long life and other advantages.

Summary

The electromagnetic flowmeter is composed of two parts by electromagnetic flow sensor and electromagnetic flow converter.The operation of an electromagnetic flowmeter is based on Faraday law of electromagnetic induction.The mainly parts of the sensor are: measuring tube,electrode poles,excitation coil,iron core,yoke and housing. The measuring tube of the sensor is a short alloy tube whose diameter is D, the inner surface of it has an insulating liner.Two electrodes are fixed in the measuring tube along with the diameter direction of it and they usually flush with the inner surface liner.When excitation coil pulsed by two-way square wave,there generates a working magnetic field with a flux density B in the vertical direction of the measurement axis.In the meantime,if some electrical conductivity liquid flows at an average velocity V through the measuring tube ,cuts lines of the magnetic field,there generates induced electromotive force E.Electromotive force E is directly proportional to the product of flux density B、measuring tube diameter D and average velocity V,that's: E BVD. Electromotive force E(flow signal) is measured by the electrodes and transmitted to transducer through cable.After the transducer handles the flow signal by magnifying it, the flow and total amount can be displayed,also will output pulse and analog current etc.
