GS 1R1B30-E-H 4th edition

Model RAKD Small Metal Rotameter

General Specifications

A float is guided concentrically in a conic metal tube. The position of this float is magnetically transmitted to the indicator. The short-tube Rotameter is used for measurement of low flow rates of liquids and gases. Its special application is in troubled, opaque or aggressive mediums and under high pressure. The instrument is mounted in a vertical pipeline with flow direction upwards.

When the process conditions are changed the scale needs to be replaced by a new one of which the values should be calculated.

FEATURES - Different process connections like internal threads

and flanges - With valves (horizontal connection)

and without valve (vertical connection) - Version with controller (only in combination with valve) - All wetted parts of stainless steel (1.4571) - Accuracy class 4 (according VDI/VDE 3513) - Round industrial standardized stainless steel housing

of protection IP 65 (on request IP 67) - Light, guided floats resulting in low pressure loss and

stable float movement - Maximum flow range 1-250 l/h water resp.

40-8000 l/h air, portioned in 13 flow ranges with a relation of 1:10

- Graduation of maximum flow ranges by factor 1,6 realised with 4 floats and 13 cone sizes

- Fine controll valve with PTFE-gasket - Electric µP-controlled transmitter with linearized output - Electrical connection by fast connection technique

(Quickon) - Inductive sensors as limit switches also in

Fail-Safe-version can be fit - Pressure controller (normal up to 25 bar at 20°C) for a

maximum flow of 100 l/h water resp. 3.250 l/h air - Connection of common transformer isolated barriers

and transmitter power supplies possible - Alignment possibility of the electric transmitters with

additional tuner (Service Box). - Also in Ex-version

Planning hints - The real working pressure has to be less than the specified pressure limit of the Rotameter. - Make sure that the wetted material is resistent to the medium. - Ambient and operation temperature has to be less than the specified maximum value. - If dirt accumulation is to be expected we recommend to install a bypass pipe. - To avoid float bouncing in case of gas application notice the recommandations of VDI/VDE 3513 Sheet 3. - To avoid mutual magnetic influence in case of a parallel design of several Rotameters take care that the distance

between the tube middle axes is not less than 120 mm. The distance to other ferrictic materials should not be less than 60 mm. - The strength of external magnetic fields close by the Rotameter should be approximately 0mT.
