Yokogawa RAMC06 Metal Short-stroke Rotameter. A float 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.
