Model RAGN
Glass Rotameter

GS 01R01B10-00E-E

The Rotameter RAGN is designed for continuous ow
measurement of liquids and gases.
The uid passes through the metering tube from bottom to
top and consequently needs to be installed vertically and
ow direction is upwards. The conical glass metering tube
includes a free rotating oat which provides self stabilization.
The actual ow is indicated by the top of the oat and can
be directly read from the scale on the metering tube.

Features:

- All stainless steel design

- Turnable splinter shield

- Designed for aggressive applications

- Easy to install and maintain

- Wide measuring range selection for gases and liquids

- Low pressure loss

- Easy to read scale

- Optional limit switches with connection box

- Suitable for applications according to IEC 61508
and Machinery Directive ISO 13849

Applications:

- Visual uid monitoring

- Industrial gas measurement

- Controlling of water circuits

Please specify in the following order

- Measuring range for water/liquid or air/gas

- With or without optional limit switch
First select the required measuring range from the ow table (last column) and specify the oat insertion for the optional limit switch. Then
the suffix code for the combination metering tube - oat can be xed.
To size the Rotameter for other medium - process- conditions use sizing program Durep V.
