Tokyo Ryuki Kogyo FLO-L68 Rotameter with Base / Level Valve

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 indicated by the float.

Area type flow meter with a base (level). Highly accurate flow rate measurement is possible in laboratories and laboratories. 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 indicated by the float. The flow rate can be freely adjusted by adjusting the valve. It is used for general equipment and panel mounting in various industries including academic research institutes.

FLO-L68 type (with base / level valve)

* Existing (old) model FLO-L65 (with 3-unit / 5-unit valve) To PL-4 special assembly

Features

  • 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)
