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 cc/m to 100 GPM, a GEMS flow switch will 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 vast 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 any mounting or space requirement.
