H2O Degree Wireless Battery Powered Water Meter

M54120 Battery Powered Water Meter Overview

The H2O Degree M54120 Battery Powered Water Meter monitors and records water consumption for tenant billing and leak detection principally in the multi-family housing industry.

The meter not only monitors usage in gallons, it also records the number of events (such as every time a toilet flushes), duration of events in gallons and time along with temperature. This provides highly accurate leak detection for the entire apartment down to individual appliances such as toilets and showers. H2O Degree can provide a daily automated leak detection report to its clients.

Point-Of-Entry (POE) – Water enters each apartment at one location, typically before the hot water heater in the utility closet. One meter per apartment.

Point-Of-Use (POU) – Riser pipe configuration, multiple points entering the apartment, feeding each toilet, sink, shower, etc. Multiple meters per apartment.

M54120 Battery Powered Water Meter Applications:
– Main feed hot or cold water
– Toilets
– Clothes washer
– Shower
– Sink with or without dishwasher

M54120 Battery Powered Water Meter

Features

  • The H2O Degree M54120 water meter is a battery powered device that
    communicates wirelessly on a 2.4 GHz 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.
  • M54120 Approvals:
    – NSF-61-G Certified
    – Meets AWWA C708 Standards
