The Rosemount 8800 MultiVariable Vortex Flow Meter option combines temperature and flow devices into a single, highly accurate instrument, eliminating the costly installation of two separate devices. The integrated, removable temperature sensor is isolated from the process and separate from the Vortex flow sensor. This facilitates independent verification or replacement of each sensor without shutdown or breaking the process seal. Additionally, the MultiVariable Vortex automatically adjusts for changes in density, making it easy to accurately measure mass and corrected volume in steam and liquid applications.
