Features
High accuracy
Accuracy is within ±0.5%
Fluid is directly measured by gear or roots, enabling accurate measuring.
Compact design
The flowmeter is compactly designed, yet the indicator is easy to read.
Excellent durability
Simple structure enables long term durability with virtually no degradation of accuracy.
FGB Type
Size :15mm (1/2B)~25mm (1B)
- Suitable for small volume flow between 40~3000L/h
- Employs gear-type rotors made of resin
FRO Type
Size : 40mm (11/2B)~50mm (2B)
- Suitable for medium volume flow between 0.8~15 m3/h (800~15,000L/h)
- Employs roots rotors made of aluminum alloy
- Roots rotors rotate without physical contact⇒Extremely low pressure loss
⇒Accuracy remains unchanged over a long period of time
FRP Type
Size : 80mm (3B)~100mm (4B)
- Suitable for large volume flow between 0.6~130m3/h
- Employs roots rotors made of cast iron
- Roots rotors rotate without physical contact
⇒Extremely low pressure loss
⇒Accuracy remains unchanged over a long period of time
