Ryuki FLO-70 Rotameter Special Assembly

Ryuki FLO-70 Rotameter Special Assembly is a high-precision area-type flow meter that can read the instantaneous flow rates of various liquids and gases directly from the scale indicated by the float. The flow rate can be adjusted freely by adjusting the valve. Used for general equipment and panel mounting in academic research institutions and other industries.

  • We will manufacture after confirming the fluid name, density, viscosity, pressure, temperature, flow range, connection standard, body material, packing material, etc.
  • For liquid measurement (Float: SUS304, etc.)
    • Density = 1.0 g / cm3 and viscosity = 1 cP as standard.
  • For gas measurement (Float: Aluminum etc.)
    • AIR 20 ° C is flown, and the flow rate value is converted to the standard state AIR, 0 ° C 1 atm (atmospheric pressure). (Unit: NL / min)
      *Products are converted to standard conditions (atmospheric pressure 20 ° C) upon request. (Unit: SL / min)
