Sekee RM Rotameters
Catalog Navigation
Sekee RM rotameters with metal tubes are designed for measuring the flow of liquids and gases, converting values into an analog 4-20 mA signal or digital HART signal. In addition to volumetric flow, they can totalize and display accumulated volume.

Specification
Sekee RM rotameters can be used across various industrial sectors. They are suitable for measuring parameters of aggressive media, providing high measurement accuracy while operating reliably under elevated temperatures and pressures.
Sekee RM rotameters are produced with varying flow path materials (stainless steel or fluoroplastic) in two mounting configurations:
— vertical;
— horizontal.
These variants enable selection of the optimal rotameter depending on the measured medium and specific pipeline installation requirements.
