PULSE COUNTER WMC
The electronic counter WMC-01 is a pulse counter to be connected to a piston water meter.
The water volume is measured by a counter using a TMR sensor with a very low current consumption. The equipment is attached directly to a piston water meter. The accuracy of the counter is +/- 0.5 liter.
Water volume as well as other warnings alike water leakage, overflow, and low battery warning are collected by a 922 Mhz wireless dongle that is connected to an Android smartphone. The distance of an obstacle-free transceiver between the reader and the device is about 50m.
The counter includes an internal memory that contains 1500 water volume data in 1 month.
NFC interface allows water utility company to configure the counter, read out the data or user to read out data with a NFC enabled Android smartphone.
