Description

Electromagnetic Flow Meter Designed for Measurement of Conductive Liquids

1. Introduction

MLF electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and consists of sensors and converters. Used to measure the conductivity of a liquid or solid. Generally, its conductivity should be greater than 5μS/cm (the conductivity of tap water, raw water is about 100~500μS/cm). it can also be used to measure various media such as acid, alkali, brine, pulp or pulp and other medium. But these medium can not contain a large number of magnetic substances and bubbles.

MLF electromagnetic flowmeter is an instrument to measure liquid fluidity. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textile, food, urban management, water plants and other industries of flow measurement.

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.

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.

3. Quick Details
