Rosemount MultiVariable 8800 vortex flowmeter

The Rosemount MultiVariable 8800 vortex flowmeter combines this firm’s proven vortex technology with a temperature-compensated mass flow output directly from the meter to reduce process variability. Unlike traditional designs that integrate the vortex and temperature sensor into the same assembly, this flowmeter has isolated, independent vortex and temperature sensors, allowing both sensors to be verified or replaced independently without breaking the process seals. This eliminates process shutdown for verification of the temperature sensor. The 8800 vortex flowmeter lowers total installed cost of temperature-compensated measurement points by 25% compared to external compensation of a traditional vortex. Cost is reduced by eliminating the need for an external thermowell, temperature sensor and transmitter, and a flow computer or control system compensation program. The unit is commonly used in temperature-compensated saturated-steam applications.
