一、Product Information
The Rotameter RAGN is designed for continuous flow measurement of liquids and gases. The fluid passes through the metering tube from bottom to top and consequently needs to be installed vertically and flow direction is upwards. The conical glass metering tube includes a free rotating float which provides self stabilization.
The actual flow is indicated by the top of the float and can be directly read from the scale on the metering tube. The Rotameter RAGN is the world´s first Glass Rotameter suitable for SIL applications and is also compliant with the Machinery Directive ISO 13849.
