Tokyo Ryuki Kogyo FLO-L65 Rotameter without Base. 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.

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)
