Positive Displacement Nutating Disc

Tight machined tolerances for exact amount of fluid for flow measurement

Liquid enters a precision-machined measuring chamber containing a disc which nutates (wobbles). The measuring chamber contains an exact known quantity of fluid.  The nutations of the disc are transmitted by a gear train to a totalizer or pulse transmitter.

  • Eliminates upstream and downstream straight run piping requirements.
  • Case material options provide flexibility of fluids – bronze, epoxy cast iron, high pressure epoxy coated carbon steel
  • Tolerant of foreign particles in the fluid
  • Temperature range up to 400 F (204 C)
