Vertically mounted, vane-operated flow switches are 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 that actuates (de-actuates) a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the fluid path. Decreasing the flow below the calibration point causes the reed switch to de-actuate.

Applications that they are well suited for include, detecting seal leakage, low flow pump protection, monitoring lube oil, verifying analyzer flow, monitoring cooling water and many other critical applications.

  • Compact and economical
  • Dependable
  • No seals
