Rotameter - Variable Area Flowmeter RAMC Variable Area Flow Meter

At first glance, the instrument looks impressive with its all stainless steel design. A closer look reveals a "float blockage" detection system. 

Operational safety is of the utmost importance in any flowmeter, and the RAMC is no exception – wetted 

parts are available in a variety of materials, and intrinsically safe outputs are available as an option.

If you value flexibility in a flowmeter – from the measurement of air to highly aggressive liquids – in situ 

replacement of the indicator without loss of performance – and the interchangeability of floats – then the RAMC is the right choice for you.

The RAMC combines all the advantages of the variable area principle with robust design, reliable measurement, 

with or without power, HART, culminating in a truly universal flowmeter for gases, liquids and steam applications. 

Model RAMC Metal Short-stroke ROTAMETER

The short-tube Rotameter is used for measurement of flow rates of liquids and gases. Its special application is in turbulent, opaque or aggressive fluids. 

The instrument is mounted in a vertical pipeline with flow direction upwards. Inside the special shaped conical metal tube, a float is guided concentrically. 

The position of this float is magnetically transmitted to the indicator. The indicators are exchangeable without influencing the accuracy.
