Unlike traditional multivariable vortex designs that integrate the vortex and temperature sensor into the same assembly, the 8800 has isolated, independent vortex and temperature sensors. This allows both sensors to be verified or replaced independently without breaking the process seals. This eliminates process shutdown for verification of the temperature sensor, as is required with the traditional design. The Rosemount 8800 MultiVariable Vortex lowers total installed cost of temperature-compensated measurement points by 25 percent over external compensation of a traditional vortex, says the vendor. Cost is reduced by eliminating the need for an external thermowell, temperature sensor and transmitter and a flow computer or control system compensation program.
