Model 700 - Rotary Flow Meter



The 700 series rotary flow meter has a simple and efficient meter design consisting of a housing and three rotors that rotate in unison within the measuring chamber. The absence of wear, from no metal-to-metal contact inside the chamber, eliminates any deterioration in accuracy and provides a long service life. The rotors are supported by bearings inserted into two bearing plates, where at the end of each rotor shaft is a timing gear. The timed rotation between each rotor is then transferred through the calibration adjuster to the register, which will then give a consistent and superior measurement of accuracy.

  • No metal-to-metal contact within the measuring chamber
  • Low Pressure Drop
  • Low Maintenance
  • Long Service Life
  • Light and Compact Design
  • Bi-directional Flow Direction
  • Wide Viscosity Range up to 1,500,00 SSU (325,000 CPS)
  • Meets NIST, OIML (MID), NMI, S.WA, SABS and many other international weights & measures
