Flow Meter Tokico 20 mm 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.
