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 as kerosene, light oil and heavy oil.
FRO Type
This flowmeters is widely used for transaction and in other applications is which a Roots type flowmeter ia most suitable
The Roots rotor rotates without physical contact, resulting in extremelylow pressure loss. In addition, its accuracy remain virtually inchanged over a long period of time.
Features :
- Wide flow range and high accuracy
The accuracy of these flowmeters is within ±5% over a wide range of flow rates (max range for heavy oil) - Small pressure loss
Because the pressure loss of these meters is low, it is posibble to perform accurate measuring at the suction side of a pump as well as accurate measurement og high viscosity fluids - Compact Design
A positive displacement type flowmeter can be used t relatively high rotating speeds, aking 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 ared switch type transmitter unut having simple construction and high reliability is available
