RAGK and RAGL small laboratory rotameters

RAGK and RAGL small laboratory rotameters

The RAGK and RAGL rotameters are specifically designed for the measurement of low flows of liquids and gases. Their main applications are in flushing systems, analysers and gas sampling, laboratories and machinery.

Integrated needle valves are available as an option and are used for fine adjustment of the flow. The special design of the RAGL makes it possible to replace the glass tube without having to remove the entire unit from the installation.

These simple and affordable rotameters have a very wide range of applications, a large variety of cones and floats, and a proven design with decades of use. The RAGK and RAGL rotameters complete Yokogawa's range of metal and glass rotameters, suitable for SIL and Machinery Directive applications.
