1. Introduction

MLF electromagnetic flowmeter works according to Faraday's law of electromagnetic induction, and is composed of sensors and converters. Used to measure the conductivity of liquid or solid. In general, its conductivity should be greater than 5μs/cm (tap water and raw water conductivity is about 100 ~ 500μs/cm), and it can also be used to measure acid, alkali, brine, pulp or pulp and other media. However, these media cannot contain a large amount of magnetic substances and bubbles.

2.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.

MLF 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.
