Kofloc 2504FR Flow Controller


Kofloc 2504FR Flow Controller are combined in this flow meter to permit high-precision measurement and control of a wide flow range from very small flow to medium flow when the gas supply pressure (inlet side) changes.

Kofloc 2504FR Features

  • This flow meter ensures constant flow under the constant pressure on its outlet side even if the pressure on the inlet side changes.
  • The flow controller is made on the basis of the Model 2204 with excellent precision control characteristics, permitting smooth control of very small flow.
  • The measuring section of the flow meter made on the basis of the high-precision float type flow meter RK1400 ensures highly reliable flow.

Standard Specifications

  • Fluids : Air,N2,O2,H2,He,Ar,CO2 (Calibration with actual gas)
    For other gases, please consult us regarding conversion conditions or calibration with the actual gas to be used.
    * Option: Scales for two types of fluids
  •  Flow range (FS): From 1–10 ML/MIN to 1–10 L/MIN (Refer to the Capacity Table on page 55.)
