Cement Grout Concrete Magnetic Flow Meter

1. Introduction

The MLF electromagnetic flow meter 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. In general, its conductivity should be greater than 5μs/cm (tap water, raw water conductivity of about 100 to 500μs/cm), can also be used to measure acids, alkali, brine, pulp or pulp and other media. However, these media must not contain large amounts of magnetic substances and bubbles.

MLF electromagnetic flow meter is an instrument for measuring liquid flow. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textiles, food, urban management, water plants and other industries flow metering.

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. Features

MLF electromagnetic flowmeter is explosion-proof design.

Low conductivity measurement function.

There are nine language options to meet the needs of different customers.

It has self-regulation function and self-test.

Different outputs are optional: Hart, RS485, Profibus, 4-20mA, frequency, pulse.
