LK-EF Insertion Electromagnetic Flowmeter |
Main Features：
●Adopts advanced low-frequency square wave excitation, featuring stable zero point and strong anti-interference capability.
●It can be conveniently installed and disassembled without stopping the water supply, either under low pressure or pressurized conditions.
●Not affected by the temperature, pressure, density, or conductivity of the measured medium.
●Especially suitable for flow measurement in large and medium-diameter pipelines.
●The sensor has almost no pressure loss and extremely low energy consumption.
●The flow measurement range is wide, with the flow velocity adjustable from 1m/s to 10m/s.
