Our radio modules transmit automatically every 8 seconds — for 12 years without changing the battery. The unidirectional transmitter is ideal for mobile reading. The external version is suitable for all types of meter equipped with a pulse transmitter (dry contact) and open collector (NPN type). Suitable pulse transmitters enable the return flow to be detected and calculated.
In the HYDRO–RADIO 868 compact version, the device is simply clipped onto the Bonyto rotary piston meter — for accurate transmission of the consumption. This version also detects the return flow automatically. Cost-effective, flexible and reliable: Send the right signals.
