RAGN Rotameter
The RAGN Rotameter is designed for continuous flow measurement of liquids and gases. The borosilicate glass metering tube has a brightly colored easy to read scale. The RAGN comes standard with in-line 316 stainless steel fittings and optional stainless steel, titanium, PTFE or PVDF internals. Connection fittings for the RAGN can be chosen from NPT thread or Flanged connections.
The fluid passes through the metering tube from bottom to top so vertical installation is required. The actual flow is indicated by the top of the float and can be directly read from the scale on the metering tube.

Product Overviews
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.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.
