Rosemount 8800 MultiVariable Flow Meters

Rosemount

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.

Features

  • Automatically compensates for changing fluid density in steam and liquid applications
  • Independently verify or replace the isolated, removable temperature sensor without breaking process seal
  • Non-wetted sensor design increases plant availability by reducing shutdowns for maintenance or repair
  • Compensate any liquid flow using up to five user-definable temperature and density pairs
  • Perform advanced monitoring with flow/temperature variables that can be assigned to the 4-20 mA, digital or pulse output
  • Improve reliability with diagnostics that constantly monitor temperature sensor health
  • A standard internal signal generator included in every meter simplifies electronics verification
