Tokyo Ryuki Kogyo FLO-PL9 Rotameter

Tokyo Ryuki Kogyo FLO-PL9 Variable Area type flowmeter with a base (level). High-precision flow measurements can be performed in laboratories, laboratories, etc.

This is a highly accurate area flow meter that can directly read the instantaneous flow rate of various liquids and gases from the scale indicated by the float. Valve adjustment allows you to freely adjust the flow rate. It is used for general equipment and panel mounting in various industries including academic research institutes.

It is a product for laboratory and minute flow rate measurement. All three sides are protected by an acrylic cover.

Technical Overview & Operating Principle

The Tokyo Ryuki Kogyo FLO-PL9 Rotameter operates on the standard variable area flow measurement principle. Fluid enters vertically through the bottom of the tapered metering tube and pushes the internal float upward.

As the float rises, the annular area between the float and the inner wall of the tapered tube expands until the upward drag force equals the gravitational force acting on the float.
