Features

• The H2O Degree M54120 water meter is a battery powered device that
  communicates wirelessly on a 2.4 GHz mesh network.
• The device provides a radio interface to remotely monitor and collect water
  consumption data from a flow sensor.
• The M54120 collects and records six registers:
  – Gallons – Number of events (event is defined as
  – Time water was flowing in minutes each time water starts and
  – Water temperature then stops flowing)
  – Heat units (calculated as Therms) – Battery Voltage
  All of the registers except temperature are cumulative or ever increasing registers.
• Even if the radio cannot transmit data, the water meter continues to record data.
• Radio is compatible with the H2O Degree secure wireless 2.4 GHz mesh network.
• By using a magnet, the installer can force a radio transmission and receive a LED sequence feedback on radio connectivity in real-time for ease/validation of commissioning.
• Type of packet data reported: Data Packet Consumption (60 minute interval default).
• Non-volatile memory maintains last reading in the event of a power failure.
• The M54120 battery has a five year warranty and can be replaced by the property’s
  maintenance staff.
• Accuracy +/- 1.5 percent. (Meets AWWA C708 Standards).
• Operating Temperature 0 to 150 Degrees F.
• Flow 0.26-7.9 gpm.
