Tokico electronic oil flowmeter FRL Tokico electronic oil flowmeter FRL

Oil, Diesel, Crude Palm Oil (CPO) Positive Displacement Flowmeter (Electronic) FRL/FRY

TOKICO FLOWMETER, TOKICO OIL FLOWMETER a high accuracy displacement type flow meter composed of two roots and measures flow directly. Tokico Oil Flowmeter has little deterioration in the instrument accuracy because a couple of roots rotates with non-contact. This flow meter measures with high accuracy and wide flow range

  • Electronic Version
  • Diesel 
  • Crude Palm Oil (CPO)
  • Petrol
  • Heavy Oil
  • Light Oil


    • 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

Now with Electronic Display:

  • Battery replacement needless for 10 years
  • Easy-to-see large LCD Character new display unit
  • Easily adjustable display angle, adjusted at 15º steps over 180º range
  • Feasible to connect with various external devices: Pulse output / Analog output / Alarm output
  • Compatible with previous model
