The SECURE Z-Wave Water Meter is a battery-powered RF module using Z-Wave® technology from SECURE, for reporting water metering from SENSUS water meter. The low-power radio signal transmits the meter readings to a Secure controller or any other 3rd party controller in the system. If there are constant powered nodes within the network, these will act as repeaters to increase network reliability. The RF module records the meter reading by backlash-free pick-up on the litre wheel of the meter register and transmits the data over the Z-Wave network either on a time or delta change. Choose the position where the unit is to be mounted, avoid locations alongside or behind large metal surfaces that could interfere with the low-power radio signals between the unit and the Controller. The unit contains a lithium battery which provide a 10 years battery life based on a 24hr reporting interval.
