Description

China Water Electromagnetic Flowmeter Electro Magnetic Cheap Flow Meter

1.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.

2. Quick Details

MLF electromagnetic flowmeter is explosion-proof design.

Function of low conductivity measurement.

4. Selection of Liner Material

Liner Material Main Performance Application
PTFE

1. Have the most stable chemical properties in plastic and resistance to boiling hydrochlor and sulfuric acid, nitric acid aqua regia, strong alkali, and all kinds of organic solvents, but can not resist the corrosion of chlorine trifluoride, high temperature nitrogen trifluoride, liquid fluorine, liquid oxygen and ozone.

2. Low abrasion resistance.

3. Low negative pressure resistance

1. -25~140℃

2. Strong corrosion medium, like strong acid and alkali

3. Healthcare medium
CR Oil proof, solvent resistance, oxidatite resistance and the resistance to the erosion of common medium like acid, alkali, salt, etc.

1. ＜80℃

2. Be able to measure sewage and mud
PU

1. Very good abrasive resistance, flexibility.

2. Low acid and alkali resistance.

1. ＜65℃

2. Neutral strong abrasion resistance medium
