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.
