Coriolis flowmeters

The smart safety instrumented system (SIS) from Emerson Process Management has been enhanced with TÜV certification of the Micro Motion SIS Coriolis meters. This certification allows users to boost plant availability by using the Micro Motion Coriolis flow and density measurement technology in safety instrumented systems in up to SIL-3 loops, per IEC 61508.

Micro Motion SIS Coriolis meters integrate into Emerson's SIS that includes the DeltaV SIS system with smart logic solvers, final elements such as Fisher Fieldvue SIS digital valve controllers and Rosemount SIS pressure and temperature transmitters.

Micro Motion SIS Coriolis meters are suitable for use in SIS applications that require a high turndown ratio of flow measurement or very accurate density measurement. These include low fuel flow (gas or liquid) to a boiler or burner, detecting composition changes via online density, such as the critical feed of reactor catalyst flows into an exothermic reaction, hazardous waste processing and incineration and numerous other critical process control applications.
