Positive Displacement Oscillating Piston

Precision machining produces accurate and repeatable measurement

Liquid enters a precision-machined measuring chamber containing a piston which oscillates (rotates) in the SmartPD Positive Displacement meter. The oscillations of the piston are transmitted through the meter wall by a follower magnet to a totalizer or pulse transmitter.

  • Highest accuracy mechanical positive displacement model
  • Eliminates upstream and downstream straight run piping requirements
  • Temperature range up to 150 F (66 C)
