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 of low-viscosity oil in heat control applications, tec. 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 ±5% over a wide range of flow rates (max range of 1 : 150 for heavy oil) - Small pressure loss
Because the pressure loss aof these meters is low, it is posibble 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 peeds, 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 constructions and high reliability is available
