A PD meter (positive displacement) is a type of flowmeter where a body is displaced by the medium to be measured. This flowmeter is the most accurate choice for viscous liquids. The interior consists of gears, a piston or lobes. A fixed volume is transmitted with each rotation. The number of rotations therefore determines the total volume and the rotation speed determines the flow rate. 

Different PD meters for liquids:

  • Oval gear flowmeters
  • Oval flowmeters (without the teeth on the ovals)
  • Gear flowmeters (round cogwheels)
  • Bi-rotor meters
  • Nutating disk flowmeters
  • Ring piston meters
  • Scummeters (sliding vane)

Different PD meters for gases:

  • Balggasmeter
  • Rotormeter

Applications

  • Liquids
  • Gases
  • Calibration measurements
