Small- and Laboratory- Rotameters RAGK , RAGL

The Rotameters RAGK and RAGL are specifically designed for the measurement of low flows of liquids and gases. Their main application field is in purging, analyzer and gas sampling systems, laboratories and machinery equipment. Integrated needle valves are optionally available and are used for the fine adjustment of the flow. These simple and affordable Rotameters have a very broad application range, large variety in cones and floats and decades of proven design. The Rotameters RAGK and RAGL complete Yokogawa´s Metal and Glass Rotameter Portfolio suitable for SIL applications and applications complying to the Machinery Directive.
