OPTION FOR AMR SYSTEM:
NWM HRI modules have been designed to fulfill requirements of all water management utilities willing to remote read their water meters. PD-SDC B6 series are pre-equipped considering actual or future evolutions towards remote reading technologies. The HRI module completely compatible with all NWM water meters equipped with the non-magnetic sensors.
1. It can be easily retrofitted and installed on meters already on the field.
2. Magnetic tampering is impossible since the non-magnetic target is not influenced by an external magnet
3. HRI module is not sensible to pipe vibrations. Parasitic pulses do not disturb metering. Remote position: 1 pulse per revolution.
