Variable Area Rotameter
The oldest and thus most mature-principle of flow measurement is a mechanical one: a floating body is guided inside a conically shaped tube. The float rises with increasing flow volume.

Product Information

Rotameter Model RAMC - Metal Short-stroke Rotameter
A float is guided concentrically to a special shaped conicmetal tube. The position of this float is magnetically transmittedto the indicator. The short-tube Rotameter is used formeasurement of flow rates of liquids and gases. Its specialapplication is in troubled, opaque or aggressive mediums.The instrument is mounted in a vertical pipeline with flowdirection upwards.The indicators are exchangeable without influence on theaccuracy.

Rotameter Model RAKD - Small Metal Rotameter
A float is guided concentrically in a conic metal tube. The position of this float is magnetically transmitted to the indicator.The short-tube Rotameter is used for measurementof low flow rates of liquids and gases. Its special application is in troubled, opaque oraggressive mediums and under high pressure.The instrument is mounted in a vertical pipelinewith flow direction upwards.

Rotameter Model RAGK - Rotameter
This type of Rotameter is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. This float is mounted in a vertical pipeline with flow directionupwards. The flow is indicated by the top of the float and can be read from the standard scale on the metering tubeor from a connected scale.

Rotameter Model RAGN - Rotameter
World´s first Glass Rotameter suitable for SIL applications
The new Glass Rotameter RAGN from Yokogawa is designed to offer maximum lifetime combined with safe and virtually maintenance-free operation and is being used for the continuous flow measurement of liquids and gases. The RAGN with reed switches has been assessed to SIL 1 acc. to the reworked IEC 61508:2010 and complies also to the Machinery Directive ISO 13849-1 standard.
