No-Moving-Parts Flow Switches


Gems Sensors & Controls  announces the launch of the new FS-600 Series "no-moving-parts" flow switches for OEM applications. The FS-600 is a robust flow switch made from durable stainless steel that works with both conductive and non-conductive fluids. Suitable for fluids with large particles and slurries, the solid-state sensor is immune to changes in viscosity. With the use of thermal dispersion technology the FS-600 will provide years of dependable worry-free service even in applications without filtration.

The FS-600 is available in various housings to suit a wide variety of pipe sizes for flow rates from .1 to 10 GPM at an affordable price. The straight through switch is designed for a long life and can be mounted in any orientation. The FS-600 can be customized with any set point based on specific customer applications.

"The FS-600 is a robust solution for customers using traditional flow switches with moving parts" says Kevin Castonguay, Product Marketing Manager for Gems Sensors & Controls. "Because there are no moving parts to jam, wear or break, the FS-600 flow sensor eliminates maintenance issues. Finally, a no moving parts flow switch is available at OEM pricing"
