LD Series Electromagnetic Flow Meter
This is a velocity-type flow meter. Based on electromagnetic induction principles, it enables accurate measurement of conductive fluids. It has no moving parts and the measurement results are independent of changes in the fluid’s temperature, pressure, viscosity, density, liquid-solid composition ratio and electrical conductivity.
Key Benefits:
No moving parts & low maintenance;
Wide measurement range;
Low power consumption;
Easy installation;
Long service life.
Working principle:
The flowmeter is equipped with detection electrodes and a magnetic field perpendicular to the direction of fluid flow. When a conductive fluid passes through, an induced electromotive force is generated at both ends of the conductor, which is mutually perpendicular to the direction of the magnetic field and the direction of motion. The magnitude of the electromotive force is proportional to the fluid's movement speed and the magnetic field strength. By detecting the electromotive force, the flow velocity of the fluid can be obtained. The flow velocity multiplied by the known cross-sectional area of the pipeline gives the fluid flow rate.
