Flow Switches

We offer highly reliable flow switches that have been engineered to specifically monitor the presence or absence of liquid, gas, or air flow in a system. Our liquid flow switches are available in vane-operated, piston, and mechanically actuated designs. We have the instruments to protect pumps, motors and equipment from the effects of low or no flow conditions. Our compact flow switch models come in piston designs to deliver proven performance in air and pure water applications. Vane flow switches are available at Transcat with field adjustability, providing count-on protection against flow variation or the stoppage of fluids, gases and flowing solids. You’ll also find brass flow switches designed to manage high inline pressure. Our switch selection includes explosion-proof products from Dwyer Instruments that have proven their worth in pipelines.
