Frequently Asked Questions

What is a GEMS SENSORS liquid flow switch used for?

A GEMS SENSORS liquid flow switch detects flow or no-flow conditions in piping systems. It is used in industrial applications such as pump protection, cooling systems, and process control to trigger an alarm or shut down equipment when flow stops.

What are the specifications of the GEMS SENSORS FS-927 flow switch?

The GEMS SENSORS FS-927 (MPN 70831) is a compact piston flow switch with a brass body, 1/4 in FNPT connections, fixed set point, normally closed SPST switch, and a DC contact rating of 20 V. It is designed for liquid service.

Where to buy a GEMS SENSORS FS-927 flow switch worldwide?

3G Electric supplies the GEMS SENSORS FS-927 flow switch to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this model.

How to install a GEMS SENSORS piston flow switch?

Install the GEMS SENSORS piston flow switch in a horizontal pipe section with the arrow on the body aligned to flow direction. Use PTFE tape on the 1/4 in FNPT threads. Wire the normally closed SPST switch per your control circuit. Test flow activation before finalizing.

Used in

Common applications for GEMS SENSORS
Cooling water systems — Gems Sensors flow sights with remote output (e.g., 1AMB2) monitor flow to critical equipment and signal alarms.
Lubrication lines — Gems Sensors flow indicators (e.g., 1AMD3) provide visual confirmation of oil flow to bearings and gears.
Process water monitoring — Gems Sensors flow sights (e.g., 1AMB9) verify flow in water treatment and chemical dosing systems.
HVAC systems — Gems Sensors flow switches (e.g., 1AMB5) detect flow in chilled water and condenser loops for pump control.
Food and beverage — Gems Sensors flow sights with stainless steel bodies (e.g., 1AMD4) are used in clean-in-place (CIP) systems for flow verification.
Power generation — Gems Sensors flow sights (e.g., 1AMB6) monitor cooling water and lube oil flow in turbines and generators.
