  • Process flow

A magnetic piston is suspended by the repulsion of a fixed magnet. When fluid flows through the unit it causes the magnetic piston to move against the repulsion of the fixed magnet. The magnet piston actuates an encapsulated hermetically-sealed reed switch out of the fluid path. Decreasing the flow below the calibration point causes the reed switch to de-actuate. Set point is adjustable.
  • Actuation points for air at 68L F and 14.7 PSIA with increasing flow
  • Deactuation (decreasing flow) averages 30% less than actuation (increasing flow)
  • Repeatability ±2%
  • Unit will pass greater flows
