Kofloc Multiple Flow Meter (for Precision Measurement for Laboratory) Model RK140X Series

Multiple Flow Meter (for Precision Measurement for Laboratory)Kofloc Multiple Flow Meter


This multiple flow meter is made by combining several types of flow meter for control of various flows in
a laboratory. It is designed based on the RK1400, a high-precision flowmeter with
 high performance. It is recommended to install one unit to facilitate flow measurement in the laboratory.


  • Multiple measurements of two to four flowmeters
    • Two to four flow meters can be attached to one unit to permit control of various gases in various flow ranges.
    • The flow meter can measure a variety of flows ranging from the very small flow of full-scale 5 ML/MIN to 20 L/MIN.
  • High-precision measurement
    • This flow meter is provided with a flow meter tube equivalent to that of the precision flow meter RK1400, permitting high-precision measurement at ±2% F.S.
  • Stand convenient for measurement
    • The model has a stand with a level adjuster for convenient use in a laboratory.
  • For measurement of multiple components
  • For measurement of multiple ranges
  • Flow checker in laboratories
