Ultrasonic water meter

The JOOBY JWM ultrasonic water meter is a reading device for measuring cold and hot water consumption in residential buildings, offices, and industrial facilities. The ultrasonic technology allows for accurate measurements without moving parts. The device features a two-row LCD for easy data readings. 

Data can also be monitored in real time via LoRaWAN or IoT connection. The meter runs on long-life batteries and its functions include an archive of readings, event logs, and alarms. It can detect leaks, pipe ruptures, reverse flow, and other problems.

Nominal water consumption for this model is 4 m3/h.

How It Works

OPERATION PRINCIPLE

The meter is installed with mounting fittings and cap nuts of an appropriate size. Once installed and filled with water, it is ready for activation and can be connected to a LoRaWAN network to transmit water consumption readings to your accounting system.

The device can store hourly readings for three months and daily readings for two years in a dedicated log. In addition, the log can store 256 latest events or alarms.

The meter is powered by two individual 3.6 V batteries with a battery life of 15 years.
