Yokogawa Metal Short-stroke Rotameter RAMC05
Yokogawa Rotameter RAMC05-A2SS-72L5-T91NNN
A float is guided concentrically to a special shaped conic metal tube. The position of this foat 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 infuence on the accuracy.
