Flow Meter Tokico FGBB835BDL-04X 25 mm

Tokico oil flowmeters are positive displacement type flow meter which are used in a wide variety of applications including measuring of boiler fuel oil and diesel oil, as well as for transactions for kerosene, light oil and heavy oil.

FGB Type

This flowmeter employs a gear-type rotor for small volume flow 0f low-viscosity oil in heat control applications, etc. It can be used without modification to measure kerosene, light oil or heavy oil. Measuring accuracy is ±0.5%.


Features :

  • Wide flow range and high accuracy

The accuracy of these flowmeters is within ±0.5% over a wide range of flow rates (max range of 1 : 150 for heavy oil)

  • Small pressure loss

Because the pressure loss of these meters is low, it is possible to perform accurate measuring at the suction side of a pump as well as accurate measurement of high viscosity fluids.

  • Compact Design

A positive displacement type flowmeter can be used at relatively high rotating speeds, making for compact design. In addition, the counter unit of these meters is compact yet easy-to-read, and construction is simple.

  • Excellent durability

The simple construction of these meters makes for longterm durability with virtually no degradation of accuracy

  • An electrical transmitter Unit attachable

A microswitch or a reed switch type transmitter unit having simple construction and high reliability is available.
