Products Description
FM/UL Approved Fire Water Flow Switch
A saddle type water flow switch is an important component in a water system that is designed to detect the flow of water in a pipeline. It is used extensively in various industries such as HVAC, fire protection, and water treatment.
The saddle type water flow switch is a device that is installed in the pipeline and is designed to detect any changes in water flow. When there is a lack of water flow or an abnormality in the flow, the switch will trigger an alarm to alert the system of the malfunction. This will, in turn, allow for timely intervention and corrective measures to be taken before any serious damage occurs.
