Helical gear flow meters/Bi rotor flowmeter

Helical gear flow meters/Bi rotor flowmeter

Helical gear flow meters are typical volumetric flow measuring instruments which directly measure the quantity of flowing liquid by means of a couple of rotors  known as helical rotors. It is a kind of positive displacement flow meters, The double case combines the rugged durability and long service life of the BiRotor flow meter . It has features as below:
  • No pulsation
  • Low noise
  • High accuracy
  • High reliability
  • Large turn down ratio
  • Small pressure loss
  • Can measure fluids with max 3500cp viscosity
  • Can work on high temperature fluids
  • Easy calibration and easy installation
Helical gear flow meter is a kind of bi rotor flow meter positive displacement , it can be mechanical type flow meter, or equipped with electronic transmitters and digital display and frequency to current converters are available for remote totalization, recording and presetting of metered volumes.
They may be used for custody transfer purposes, operating controls and for the many other needs of the petroleum, chemical, pharmaceutical industry, etc.
