GEMS SENSORS Liquid Flow Switch: Piston, Polypropylene, 3/4 in FNPT, 3/4 in Connection Size

The GEMS SENSORS FS-500 is a general purpose piston flow switch used to detect liquid flow or no-flow conditions in industrial piping systems. It is commonly applied in water treatment, cooling systems, and process control where a fixed set point and normally open switch position are required.

The GEMS SENSORS 170232 (FS-500) is a polypropylene piston flow switch with 3/4 in FNPT connections. It has a fixed set point, normally open switch position, and a contact rating of 20 V DC. The body material is polypropylene, suitable for many liquid media.

GEMS SENSORS flow switches are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for pricing and lead time on the FS-500 or 170232 model.

Install the GEMS SENSORS piston flow switch in a horizontal pipe section with the arrow on the body aligned with flow direction. Use PTFE tape on the 3/4 in FNPT threads. Ensure the electrical circuit is off before wiring the normally open contacts. Consult the manufacturer's manual for torque and wiring details.
