Kofloc 2504FR Flow Controller

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.
