Kofloc RK120X Multiple Rotameter

Kofloc RK120X Multiple Rotameter is a multiple flow meter with a needle valve that is made by combining several types of flow meter for controlling various flows in a laboratory. It is designed based on the RK1200, a flow meter with a precision needle valve, and has been verified to have outstanding reliability.


  • Multiple control of two to four flowmeters
    Two to four flow meters can be attached to one unit to permit the control of various gases in various flow ranges.
  • 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 and control
    This flow meter is designed based on the precision flow meter RK1200 and permits control of very small flow and high-precision measurement (FS ±2%).


  • Control of multiple components
  • Multiple range control
  • Flow control in laboratories
