Model RAGK
Small Glass ROTAMETER

GS 01R01B07-00E-E

Rotameter RAGK is designed for the measurement of
clean liquids and gases.
The conical glass metering tube has a free rotating
oat. The Rotameter is mounted in a vertical pipeline
with ow direction upwards. The ow is indicated by
the top of the oat and can be read from a scale on
the measuring tube or from an attached scale.

FEATURES

• Large selection of measuring ranges

• High repeatability by a free rotating oat even at low
ow rates

• Low pressure loss

• Visual check of the medium

• Non-powered local indication

• Large selection of scales

• Optional built-in regulation valve

• Optional limit switches

Typical Applications

• Transparent liquids

• Low viscous liquids

• Gases

Measurable ow rates:

• Water, 20 °C (68 °F):

0.002 l/h to 630 l/h

0.2 l/h to 6300 l/h
(0.05 gph to 1664 gph)

The measureable ow rates are depending from
density and viscosity of the uid. To nd the uid

The accuracy is given under calibration conditions. For
liquid service it has to be taken into account, that the
indication is viscosity dependent and the accuracy can
only be kept if the temperature is constant.

FLOW CONTROLLER, option /R1 and /R3 for

0123

RAGK41

Flow regulator for constant ow in case of variations in
process pressure.
These are no valves to reduce the pressure.

• Flow Controller /R1 for liquids and gases
The regulator keeps the ow rate constant in case of
a variable inlet pressure and constant back pressure.
For gases the process conditions are the back
conditions. The inlet pressure should be minimum
400 mbar larger than the back pressure (see Fig.3).

• Flow Controller /R3 for gases with uctuations of

the back pressure and constant inlet pressure.
The process conditions are the inlet conditions.

The inlet pressure should be minimum 400 mbar
larger than the back pressure.

Max. liquid ow: 100 l/h (26.4 gph)
Max. gas ow: 3250 l/h (858.56 gph)
Max. pressure: 25 bar (362.6 psi)
Temperature range: -20 °C to +80 °C

(-4 °F to 176 °F)

(atmosphere conditions).
For the smallest owrate the regulation works best from

0.4 bar (5.8 psi) to 3 bar (43.5 psi) (or more) inlet pressure
change, for the largest owrate from 0.9 bar (13 psi) to
3 bar (43.5 psi) (or more).
