 flow meter and interface




Flow Meter is a Z-WavePlus enabled device that measures water flow. Detects, measures, and monitors your water utility and it will send alerts on your Z-Wave network. The FMI is compatible with other Z-WaveTM and Z-Wave Plus certified products.


SPECIFICATIONS for FMI (Z-WavePlusTM enabled device)

Power: 5 volts (nominal) DC from regulated Power supply @~ 500mAcapability with optional AA alkaline battery (2) backup

Battery Life (without AC Mains): 40 hours depending on battery capacity/quality and no alarms and default Z-Wave network settings. The FMI typically is not powered by the AA batteries. The batteries are optional; they will keep the FMI functional during short power outages and will maintain continuity of the water usage data for customers who prefer to have historical usage data. The battery life while running on AC main power is generally the normal shelf life.
