Factory direct sale
Description
The FSF micro flow switch is primarily used to measure and control the flow of liquid in a pipe, such as alcohol or water. It is a flow switch with paddles, designed to protect water cutouts in the water and heat pump unit. The FSF flow switch, as a small flow valve, uses an SPST switch to ensure it works quickly for instantaneous protection. It is designed with a special plastic cover for a high condensation rate and low influences from heat and cold.
The FSF-YK flow switch is outfitted with a single pole single throw (SPST) connection, making it reliable, highly sensitive, and carries out operation quickly to ensure an instantaneous flow switch function. It is outfitted with an enhanced engineering plastic design while still maintaining a simple structure for easy use and stable operation.
