The Variable Area Flowmeter is one of the oldest and mature principles in flow measurement with its simple design: a float rises inside a conically shaped glass tube as the flow increases and its position on a scale can be read off as the flow rate.

Thie Mini Rotameter RAGK is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. Measureable Flow Rate: Water = 0.002 l/h to 600 l/h; Air = 0.2 l/h to 6300 l/h
The Rotameters RAGK/ RAGL are specifically designed for the measurement of low flows of liquid and gases. Their main application field is in purging, analyzer and gas sampling systems, laboratories and machinery equipment.
The Plastic Rotameter RAQN is designed for measurement of liquids and gases. The conical plastic metering tube has a free rotating float. Measureable Flow Rate: Water = 10 l/h to 10 m3/h; Air = 0.16 m3/h to 250 m3/h
In the 1990s, Yokogawa strengthened its focus on flowmeters through cooperation with and the eventual acquisition of the German flowmeter manufacturer ROTA. In so doing Yokogawa gained access to 100 years of flowmeter expertise and completed its flowmeter portfolio by adding the Rotameter (variable area) and Rotamass (Coriolis) product lines.
