Introduction
Electromagnetic flowmeter is only applicable to measure the flow of conductive liquid, which is wide used in water supply, sewage water measuring, industry chemical measuring etc. The remote type is with high IP protection class and can be installed in different locations for the transmitter and converter. Output signal can pulse,4-20mA or with RS485 communication.
Specification
Measuring principle
Mag meter works based on Faraday's law, when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:
E=K×B×V×D
Where:
E－Induced electromotive force
K－Meter constant
B－Magnetic induction density
V－Average flow speed in cross-section of measuring tube
D－Inner diameter of measuring tube
