L54120+ Water Meter
Description
The L54120+ Water Meter is a battery-operated, LoRaWAN-based, wireless water meter. It measures water flow in gallons and record the number and duration of water usage events; the meter records total water consumption, water usage events, and water temperature The device is equipped with LoRaWAN secure wireless 915 MHz technology that offers line-of-sight, bi-directional communications of over six miles, reducing the need for repeaters. Additionally, the device requires no electrical connections.
With their long-range wireless connectivity, the units can operate within a 1,000-ft (305-m) radius from the gateway. Utilizing H2O Degree’s Smart Metering wireless data acquisition system and PC-based software, the L54120+ water meter collects and reports water consumption data at granular levels.
Specs
- The H2O Degree L54120+ water meter is a battery powered device that communicates wirelessly over a LoRaWAN secure wireless 915 MHz network
- LoRaWAN radio infrastructure provides the longest range in the industry for communication distances, eliminating the need for repeaters, all over a secure open protocol network
- The device collects and records six registers:
- Gallons
- Time water was flowing in minutes
- Number of events (event is defined as each time water starts then stops flowing)
- Water temperature (once/day)
- 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
- 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 L54120+ battery has a five year warranty and can be replaced by the property’s maintenance staff
- Accuracy +/- 1.5% (Meets AWWA C708 Standards)
- Operating temperature 0 to 150°F (-18 to 66°C)
- Flow 0.26 to 7.9 gpm
- L54120+ approvals:
- NSF-61-G Certified
- Meets AWWA C708 Standards
- MA Board of Plumbers Approved Cert. # P1-0918-94
