Gems' line of flow switch devices and pressure switch instruments feature a broad range of configurations for use in liquids or gases. At preset rates, ranging from 50 cm³ per minute to 100 gpm, a Gems flow switch can be used to initiate alarm actuation or automatic shutdown of a system. These flow switch units feature high quality, corrosion-resistant materials for use in the toughest environments. Material choices, ranging from stainless steel to Ryton, offer a wide range of chemical compatibility. Versions include switches with fixed or adjustable actuation settings, models for viscosity compensation or high pressures, in-line models and designs to satisfy most mounting or space requirements.
The FS-380P series inline flow switch offers the same performance and resistance to clogging as its metal cousin (FS-380). The fixed set point and simple design make it a dependable switch. This flow switch is a good choice for coolant applications requiring reliable flow detection in HVAC, semiconductor, welding, medical and other industries. ¼" quick disconnect units have a wide range of snap-on mating fittings sold separately to fit most piping requirements.
The key to the performance of the FS-380P switch is the dual diameter internal bore. At flow rates below the actuation point, the fluid passes around the piston and metering disc within the metering bore. As fluid flow increases past the actuation point, the metering disc enters the flow bypass bore where the increased diameter provides a generous flow path. The result is a low pressure drop for high flow rates and less susceptibility to fouling.
