Vane-actuated flow switches are designed for direct sensing of liquid flow in pipelines. These switches are magnetically actuated and feature rugged internal construction and all stainless trim. Minimum line pressure loss is provided by vane position at actuation.

The Model T21Point Level Switch uses a thermal differential technique to measure liquid flow, level or interface by sensing changes in the thermal heat transfer characteristics of the media where it is located.

Type 1520 is a vertically mounted, vane-operated flow switch suitable for plant and OEM applications where open or closed contacts are required to signal flow or no flow conditions. The vane extension arm moves a magnet which actuates (de-actuates) a hermetically sealed reed switch.
