Magnetic flow meters, also known as mag meters, electromagnetic flow meter are, widely used in a variety of industrial field applications due to their reliable flow rate measurements and features such as low-pressure loss and maintenance-free operation.
Apure’s AXT series magnetic flow meters are designed with dual-frequency excitation to achieve stable measurement, zero stability, and quick response times.
Working principle of electromagnetic flow meter
The working princple is based on Faradays Law of Electromagnetic Induction, that is, when the conductive liquid flows though the electromagnet flowmeter the duced comotive force w be produced in the conductor, and the induced elecom force is diectly poona to the velocity of conductive liquid magnetic flux density and with of conductor(inside diameter of flowmeter)
Such induced electromotive force is detected by a pair of electrodes on the tube wall of the flowmeter, and the rate of flow can be acquired by mathematical operation The quation of nduced electromotive force is as follows:
E = D · V · B
E: induced electromotive force
D: inside diameter of measuring pipe
B: magnetic flux density
The following conditions should be satisfied in order to obtain satisfactory measuring accuracy.
- The tested liquid shall possess the electrical conductivity
- The pipe shall be full of liquid
- The components of liquid shall be well mixed
- If the liquid has magnetic permeability, the magnetic field of the flowmeter will change, so the flowmeter shall be modified
