FRO Type
This flowmeter is widely used for transaction and in other applications is which a Roots type flowmeter is most suitable.
The Roots rotor rotates without physical contact, resulting in extremely low pressure loss. In addition, its accuracy remain virtually unchanged over a long period of time.
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.
