The Yokogawa RAMC Short Stroke Rotameter has a float that is guided concentrically to 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 flow rates of liquids and gases. Its special application is in troubled, opaque or aggressive mediums. The instrument is mounted in a vertical pipeline with flow direction upwards. The indicators are exchangeable without influence on the accuracy.

At first glance the instrument looks impressive with its all stainless steel design. A closer look reveals a unique patented "float blockage" detection systems. 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 degradation of performance – and the inter-changeability of floats, – then the RAMC is for you.

The RAMC combines all the advantages of the variable area principle with robust design, reliable measurement, with or without auxiliary energy, culminating in a truly universal flowmeter for gases, liquids and steam applications.
