Product Description

MLF electromagnetic flow meter, composed of sensor and converter, works based on Faraday's law of electromagnetic induction law. It is used to measure electrical conductivity of liquid or solid. Generally, the electrical conductivity should be over 5υS/cm(electrical conductivity of tap water, raw water is about 100~500υS/cm),It can also be used to measure various media like acid, alkali, saline solution, paper pulp or pulp and so on. But these media can't contain a lot of magnetic materials and bubbles.

MLF electromagnetic flow meter is a kind of instrument which is used for measuring the flow conductivity liquid. The meter is widely used in flow measuring of Metallurgy, Chemical Industry, Paper Industry,Environmental Protection, Oil Industry, Textile Industry, Food Industry and City Administration, Water Works,etc.
 
Working Principle

The principle of the sensor is based on Faraday's law of electromagnetic induction.It is installed a pair of detection electrodes on the pipe wall,where the measurement pipe axis and magnetic field lines are vertical. When the conductive liquid cuts magnetic field lines and produces induced electromagnetic force.Which can be measured by the two electrodes on the meter pipe.The result can be calculated by formula: Induced electromotive force,(flow signal)

E=KBDV
E--Induced electromotive force,V;
K--meter constant;
B--Magnetic flux density,T;
D--Internal diameter of measuring pipe,m;
V--Average velocity of pipe section,m/s.
1MLF Series Electromagnetic Flow Meter
Assume the volume of liquid as qv(m3/s),qv=πD2V/4),so in the formula E=(4kB/πD)qv=kqv, K is meter constant,K=4kB/πD.
Actually, the electromagnetic flow meter consists of two parts, transmitter and sensor, the measuring electrodes inspect the electromotive force, and transmit to the converter, the converter provides excitation current. E is usually called a flow signal, after processing the flow signal by converter, output 4~20 mA/pulse(or frequency) signal which is proportional to the flow rate, then the flow rate recording,adjusting can be achieved.
