STFS-25 water flow switch, NPT threaded connection, SPDT contacts, 6–380 V

General Description

The STFS-25 water flow detector is a high-quality device designed to detect variations in the flow rate of liquids such as water, ethylene, and ethylene glycol in pipes. It is equipped with a single-pole, double-throw (SPDT) contact that allows the power to a circuit to be cut off when the flow rate exceeds or falls below a defined threshold. This device is ideal for applications requiring locking or cut-off protection, and it is completely sealed, making it suitable for a variety of environments.
