Metal Variable Area Meter - RAKD
Small Metal Rotameter

A float is guided concentrically in a special shaped 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.

• The original from the inventor of the Rotameter
• Simple and reliable
• Can be equipped with control valve
• For flow ranges from as low as 0.1 l/h water
• Large variety of "specials" are available
• 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.
• Graduation of maximum flow ranges by factor 1,6 realised with 4 floats and 13 cone sizes
• Fine controll valve with PTFE-gasket
• Electric uP-controlled transmitter with linearized output also in Ex-version
• 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)
