Electromagnetic flowmeter consists of two parts: sensor and converter. It works according to Faraday electromagnetic induction law and is used to measure the volume flow rate of conductive liquid whose conductivity is greater than 5uS/cm. It is an inductive instrument for measuring the volume flow rate of conductive medium.The main components of intelligent electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and magnetic yoke shell.It is mainly used to measure the volume of the general conductive liquid and the uniform liquid solid suspended liquid in the closed pipe such as mud, pulp, pulp and corrosive liquid such as strong acid and strong base.

Electromagnetic flowmeter can display fluid flow, and can output pulse, analog current and other signals, used for flow control and regulation such as water, sewage, mud, pulp, all kinds of acid, alkali, salt solution, food slurry.With the advantages of rectangular wave magnetic field, the two electrodes are fixed on the measuring tube through the wall along the direction of tube diameter.The electrode head is basically flush with the inner surface of the lining.The bi-directional under square wave pulse magnetic field coil, will be in a direction perpendicular to the measuring tube axis to produce a magnetic flux density B work after magnetic field converter will flow signal amplification processing, intelligent anticorrosive electromagnetic flowmeter is widely used in petroleum, chemical, metallurgical, textile, food, pharmaceutical, paper making industries and environmental protection, municipal administration, water conservancy construction and other fields.

Application of electromagnetic flowmeter:

1 strong acid, alkali and other corrosive media

2. Sanitary media

3. Water, sewage, weak abrasion mud pulp

4. Neutral strong wear mud, slurry, coal slurry
