Electronic register EWM is designed to replace the traditional mechanical counter of multijet and piston water meter. This device uses  AMR sensor to determine the number of turns, then calculate the volume and the flow rate. The EWM is a breakthrough solution for low power consumption, along with many other notable features that the mechanical counter does not have
