ROTAMASS is the integral and remote type Coriolis Mass Flow Meter. Both types have highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved.

Coriolis Flow Meter ROTAMASS employs a flame-proof type converter case suitable for use in the hazardous area together with its intrinsically safety type detector.

Coriolis Flow Meter ROTAMASS's signal processing, housing protection and its detector's special decoupling system against external loads and vibrations, realize high performance in real applications.

Details

The RotaMASS 3 Series mass flow meter features a heavy wall, seamless, dual tube design uniquely decoupled from any process vibration or pipeline stress guaranteeing reliability and output stability. Nine different detectors enable customization of the meter for the best combination of mass flow range, pressure drop, and accuracy at the lowest possible cost. The versatile RotaMASS can be used in the most difficult applications from cryogenics to molten liquids as well as sanitary applications and aggressive chemicals. With its multi-measurement and multi-parameter capability, the RotaMASS is essentially a process control station. The state of the art converter provides a wealth of features including remote configuration via HART, multiple languages, advanced diagnostics, infrared programming and a four-line display for easy setup and operation.
