Tokyo Ryuki Kogyo Flo-PL Series Rotameter

It is a high-precision area type flow meter that can directly read the instantaneous flow rate of various types of liquids and gases from the scale on the glass tube indicated by the float.

It is a high-precision area type flow meter that can directly read the instantaneous flow rate of various types of liquids and gases from the scale on the glass tube indicated by the float.

  • We will manufacture after confirming the fluid name, density, viscosity, pressure, temperature, flow rate range, connection standard, body material, packing material, etc.
  • For liquid measurement (float: SUS304, etc.)
    * Density = 1.0 g / cm3 and viscosity = 1 cP are standard.
  • For gas measurement (float: aluminum, etc.)
    * The flow rate is displayed by flowing AIR 20 ° C and converting it to the standard state of 0 ° C atm (0.101MPa (A)). (Unit: NL / min)
    * Manufactured in standard condition (atmospheric pressure 20 ° C) upon request. (Unit: SL / min)
