Features



  • Measurement with high accuracy

Because the fluid is directly measure, the integration accuracy of this flow meter is within ±0.5% (The accuract within ±0.2 is also available according to the demands for a dealing and a tax certificate, etc.) Especially, because a pair of roots is non-contact, a light material can be adopted for the TOKICO FLOWMETER. And low viscosity fluids can be measured with high accuracy and wide flow range.

  • Small size and light weight

Because the roots is adopted for the rotor, discharging fluid volume in one rotation of rotor is larger and the roots meter is designed small and light.

  • Excellent stability of accuracy

Mechanical parts of the roots meter do not wear because of non-contact rotation and there is little change of instrument accuracy in a long time operation.

  • Excellent durability

Because the roots meter rotates without contact, the rotor is excellent in durability.

  • Small pressure loss

The pressure loss is smaller than another displacement type flow meter because the rotors do not contact each other.

Suitable for:

  • Light Fuel Oil (Diesel)
  • Crude Palm Oil (CPO)
  • Heavy Oil
  • Other oil
