Water Leak Detection Sensor – Type BPWD

Application of Water Leak Sensor

We have designed the Battey Powered Water Leak Detection Sensor to detect leaks in areas without access to mains power, making installation effortless. It provides dependable water leak detection for toilets, basements, attics, utility rooms, and numerous other locations. You can customize its length to suit your specific needs by cutting down the 1m water detection cable it comes with.

How Water Leak Sensor Works: Advanced Features for Effective Water Damage Prevention

Two AA batteries power our Water Leak Detection Sensor. It emits a single “Battery Low” beep when the batteries require replacement. When water is detected, it produces a repeating multi-tone beep every 23 seconds.

It’s important to note that this sensor does not provide outputs to Building Management Systems or shut off the water supply. If you require these functionalities, we recommend visiting our website to find out more about our Wireless Water Leak Detection Alarm – Type RFWD.
