GEMS SENSORS FS-150 Low Pressure Drop Piston Flow Switch

The GEMS SENSORS FS-150 is a low pressure drop piston flow switch used for flow detection in industrial piping systems. It is ideal for applications requiring a fixed 1.0 GPM set point, such as cooling water lines, lubrication systems, and process control loops where reliable flow/no-flow indication is needed.

The GEMS SENSORS FS-150 is a polypropylene piston flow switch with 1/2 in NPT connections. It has a fixed set point, normally closed switch position, and a contact rating of 20 V DC. The manufacturer part number is FS-150, NC, 1.0GPM. It is designed for low pressure drop flow detection at 1.0 GPM.

3G Electric supplies the GEMS SENSORS FS-150 liquid flow switch worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this fixed set point, normally closed piston flow switch globally.

Install the GEMS SENSORS FS-150 in a horizontal pipe section with the flow arrow aligned to flow direction. Use PTFE tape on the 1/2 in NPT threads to prevent leaks. Ensure the switch is wired to a 20 V DC circuit per the normally closed configuration. Test the set point at 1.0 GPM to verify proper flow detection.
