Battery Powered Electromagnetic Flow Meter

Battery powered Electromagnetic flow meter is mainly used on the sites which have no external power supply, to measure the volume flow of water, waste water, sewage, beverage, slurry, the fluid temperature usually not more than 120℃, fluid’s conductivity not less than 5μS/cm.

Standard configuration: Lithium battery powered (3.6V / 19AH),  can support flow meter continuously working for about 5 years.
