Totalizing unit mechanical type FGB Type


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.


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
Accuracy ±0.5%
