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
