PROVEN PERFORMANCE IN EVERY PROCESS

Gems Sensors & Controls offers a broad range of flow switches including Piston, Shuttle, Paddle & Electronic. With configurations for use in liquids or gases and material choices ranging from stainless steel to Ryton, Gems flow switches offer a vast range of chemical compatibility. Switches are available with fixed or adjustable actuation settings, models for viscosity compensation or high pressures, in-line models and designs to satisfy any mounting or space requirements.

Gems Sensor Flow Switches:

🔹FS-200 Shuttle Flow – Use for water or oil, ideal for detection of improper flow rates in high volume lubrication, cooling or process systems, with 1% repeatability.

🔹FS-380 Piston Flow – Inline flow switch using 100 micron filtration less susceptible to clogging, ideal for high-pressure applications and cooling applications

🔹RFS Rotorflow – Combines visual confirmation of flow with dynamic, electronic switch operation.

WHICH FLOW SWITCH DO I NEED?

Gems Sensors Flow Switches for liquid flow indicate when a system has lost flow or has too much flow. Flow switches will not indicate the actual flow rate, they will only indicate when flow has reached the setpoint. If your application requires you to know the flow rate, then you will need a flow sensor like Gems Rotor Flow or Gems Flow Turbines. For Flow Switches the First Step is to review the average flow rate in your system, which will then determine what flow setpoint you need.
