IP67 JIS10K Flange Type Electromagnetic Flow Meter

                                             Magnetic Flow Meter JIS10K Flange Type

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.
