OPTION FOR AMR SYSTEM:
GALONMETER AMVmodules have been designed to fulfill requirements of all water management utilities willing to remote read their water meters. GL-VM-SD2 series are pre-equipped considering actual or future evolutions towards remote reading technologies. The HRI module completely compatible with all GALONMETER 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. AMV module is not sensible to pipe vibrations. Parasitic pulses do not disturb metering. Remote position: 1 pulse per revolution.
