 Modulevel® Pneumatic Displacer Liquid Level Control   Printer Friendly Version
Modulevel pneumatic liquid level controls are displacer actuated level sensors that provide output signals in direct proportion to changes in liquid level.
Operating Principle Features Industries Options Downloads Approvals
 
As the buoyancy force on a displacer changes with liquid level movement, a range spring supporting the displacer extends or compresses, moving a magnetic ball. A magnet carriage within the controller head follows the ball producing a change in output.

 

  • Stable output signal is unaffected by surface turbulence
  • Standard models handle pressures to 294 bar (4265 psig)
  • Good for process temps. from -100° to +370° C (-150° to +700° F)
  • Visual indicator is independent of air supply
  • Accurate output signal provided over a wide specific gravity range
  • 316 stainless steel displacer and trim
   

  • Pneumatic to current interface transducer for electronic control
  • Electric high and low limit switches
  • Sealed or flanged chambers
  • Direct or reverse acting output signal
  • Level ranges from 356 to 3048 mm (14 to 120 inches)
  • Transmitter or differential gap options
