2 inch Water Flow Meter types

2 inch magnetic flow meter

Magnetic Water Flow Meter is an electromagnetic flowmeter used to measure conductive fluids. Conductive liquids such as drinking water, sewage, wastewater, seawater, ammonia, cement slurry, etc.

Magnetic Water Flowmeters provide highly accurate flow measurements for a wide variety of conductive fluid applications. Magnetic Water Flow Meter is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm. Based on Faraday’s law of electromagnetic induction. Magnetic Water Flow Meter is ideal for wastewater applications or any dirty liquid which is conductive or water-based. It is widely used in water treatment, environmental protection sewage measurement and control, papermaking, and other industrial and agricultural production processes for flow measurement and control.

2 inch magnetic flow meter reference price: USD 500.00/pc.
