Electromagnetic Water Meter
Electromagnetic Water Meter
042CWM
Features
- Accuracy: Class 2(Please see datasheet for details)
- Theoretical value: Water: Min. 20μS/cm; Other liquid: Min. 5μS/cm
- Recommended value: ＞30μS/cm

Overview The best option for gauging tap water flow is the electronic water meter. This kind of flow meter measures the flow using electromagnetic induction and Faraday’s law.
Principle Electronic Water Meter for flow measurement
Based on Faraday’s law, a mag meter generates the electromotive E that is proportional to the flow speed v when the liquid passes through a pipe with a diameter of D at a flow rate of v. Within the pipe, an exciting coil creates a magnetic flux density of B.
