Customer Testimonial

  • Game Changer

    We found the transition to Freelance went very smoothly. The product and support have been exceptional. It has opened windows into our plant that we never had. We’ve been very satisfied with the ABB system.

  • You can't beat the price

    Winn Marion's retrofit eliminated a whole lot of linkage, probably 6 joints, and wherever you have a joint you have problems. Right now both the turbines are running the best I have ever seen in my 30 years of maintaining them.

Displacer Level Measurement


Displacer Level Measurement

Magnetrol's Pneumatic Displacer Liquid Level Control is a simple modular actuated level sensor that provides output signals in direct proportion to changes in liquid levels. The key elements of the pneumatic control are the magnetic coupling, allowing the controller to be mechanically isolated from the sealed sensing unit; the range spring, which converts the change in buoyancy force on the displacer in motion; and the controller head, providing a modulated pneumatic signal to the motion of the spring. The pneumatic displacer liquid level control is applicable in steam generator feed water heater regulation, fractionating column level transmitters, ethanolamine level transmitters, vent gas scrubber level control, drip pot condensate level control, flash tank level transmitter, and boiler level control.


  • Stable output signal is unaffected by surface turbulence
  • Standard model handle pressure up to 4265 psig
  • Process temperatures from -150o to 700oF
  • Visual indicator is independent of air supply
  • Accurate output signal provided over a wide specific gravity range
  • 316 stainless steel displacer and trim
  • Controller head removable without disturbing pressure boundary
  • Easily calibrated without moving tank liquid level, thereby reducing installation time and cost
