DN80 sewage electromagnetic flowmeter

Sewage electromagnetic flowmeter measurement principle:

It is the principle of magnetic line cutting. When the liquid flows, the magnetic force lines are cut, so that the flow velocity of the liquid is analyzed. Then, the real-time volume of the liquid is calculated through the flow rate x pipe and the section. The main components of lt-lde magnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell.
