The compact electromagnetic flowmeter (also magmeter, mentioned as magmeter in the following content) integrates the traditional magmeter’s transmitter and sensor into a single unit. With its compact design and flexible installation, it features an infrared remote control for easy commissioning and mounting. Widely used across various industries, it measures the volumetric flow rate of conductive liquids with a conductivity greater than 2μS/cm. This inductive instrument is specifically designed for measuring the volumetric flow of conductive media.

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 Tube Constant
B－Magnetic Flux Density
V－Average Flow Velocity
D－Electrode Spacing
