Product Description

Product Description

 

A water flow detector is a device that detects the presence of water flow in a certain area. It is designed to detect the movement of water and send out a signal if it detects a specified amount of flow. This device is commonly used in commercial and industrial settings where water flow needs to be monitored for safety reasons.

 

Water flow detectors can be installed in numerous places such as in the basement, kitchen, and bathroom. They can also be used in outdoor areas such as ponds, swimming pools, and fountains. A water flow detector typically works by analyzing changes in the flow rate of water passing through it. If the flow exceeds the preset level, the detector will activate an alarm or send a signal to a monitoring system.
