Flowmeters

Electromagnetic Flowmeter

For conductive liquids in water, wastewater and chemical applications.

Electromagnetic flowmeters are used for conductive liquid measurement where moving parts are not required. Selection depends on conductivity, lining material, electrode material, pipe size, flow velocity and chemical compatibility.
