Flange type electromagnetic flowmeter consists of the converter of EMF85, and the sensor of flange type.

Flange type sensor uses the way of connecting the flange with pipe,It has various types of electrode material and lining material.

The sensor and converter can be combined into intergrated or split electromagnetic flowmeter.

Flange type electromagnetic flowmeter can be widely used not only in genaral process test,but also in the chemical industry,water-supply,waste-water monitoring ore pulp or paper plup etc.
