Electromagnetic flow meter is our commonly used water flow meter

 

The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube
is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium
flows through, the conductive liquid moves in the magnetic field and cuts the magnetic field lines, and an induced electromotive force E perpendicular to the direction of movement and the
direction of the magnetic field will be generated at both ends of the conductor. This electromotive force is proportional to the flow rate V of the conductive liquid, that is, E = BLV (where B is
the magnetic induction intensity, L is the length of the conductor, and V is the speed of cutting the magnetic field lines).

 

Electromagnetic flow meters determine the flow of conductive liquids by measuring the induced electric potential generated on electrodes on both sides of the pipe. Since the induced potential
is proportional to the flow rate, the flow rate of the fluid can be deduced by measuring the induced potential.

 

This measurement method has many advantages. For example, the measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. At
the same time, the electromagnetic flowmeter has no moving parts, no flow-blocking parts, no pressure loss, and no It will cause problems such as wear and clogging. Therefore,
electromagnetic flow meters have been widely used in sewage treatment, chemical industry, metallurgy, papermaking, food and other industries.

 

Electromagnetic flow meter is really the most economical and accurate flowmeter for water flow measurement. If you want to buy a flowmeter, you are welcome to consult CIXIFM winny at any time:
