Features

High accuracy

Accuracy is within ±0.5%
Fluid is directly measured 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)Tokico flowmeter

  • 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
