FS-200 Series Adjustable Flow Switch

Brand: Gems Sensors, Inc

The FS-200 Series offers accurate flow detection, with 1% repeatability over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil.

Generous flow paths keep pressure drop low. 

These switches are ideal for detection of improper flow rates in high volume lubrication, cooling or process systems.

FS-200 Series Adjustable switches offer the same accuracy and are as rugged as those with fixed settings, but provide one additional feature: external adjustability. 

With these versatile switches your choice of flow settings is diverse within a given range. An ordinary, flat-blade screwdriver is all that's required for the actuation adjustment.
