Flow Switches for Gases

Gems Sensors manufactures flow switches for liquids, but did you know that we also manufacture flow switches for Gases!  When selecting the correct switch, it’s important to know the line pressure the switch will be on, as that will affect the flow switches set point.  Unlike liquids, gases are compressible, so different pressures will alter the set point’s accuracy.  Below are the Flow Switches that can be used to indicate flow in a gas application.
