Ultrasonic water meter

The JOOBY JWM ultrasonic water meter is a high-precision 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 convenient data reading and can be connected to LoRaWAN and IoT for real-time monitoring. 

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 meter is 2.5 m3/h.

How It Works

OPERATION PRINCIPLE

The meter is installed with mounting fittings and cap nuts of an appropriate size, followed by its connection and activation. Once mounted and filled with water, the meter is activated and can be connected to the LoRaWAN network to transmit water consumption readings to an accounting system.

The device can store hourly readings for three months and daily readings for two years. 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.
