Flow Switches

Flow switches are unique in the field of flow controls, actuated by flow, not pressure and are simple mechanical devices. They are specifically designed to accommodate customers’ applications with minimal pressure drop. The flow switches are completely field adjustable, available in any electrical rating desired, any type of connection, most metals, Teflon and plastics. Also they are available in explosion proof and non-explosion proof models.

The desired flow indication (increase, decrease, reverse) is transmitted mechanically from the line media by deflection of the paddle through the stem and bellows or flexure tube assembly, causing micro-switch actuation and resultant electrical contact for transmission of signal to whatever ultimate point desired.
