8800 MultiVariable™ Vortex Flowmeter

Summary:

The Rosemount 8800 Multivariable Vortex Flowmeter combines yourtemperature and flow devices into a single, highly accurate instrument,eliminating the costly installation of two separate devices. And with itsnon-wetted sensor design, shutdowns for maintenance or repair aren’t even anissue.

MultiVariable™ Vortex can save up to 30% per installation by eliminatingthe need for external temperature compensation for saturated steamapplications.

Integral temperature sensorenables temperature compensated mass flow for saturated steam
Removable temperature sensoreliminates the need for process shutdown for temperature sensor verification orreplacement
Mass flow, volumetric flowor temperature are available as configurable outputs

Applications

The Rosemount 8800 MultiVariable Vortex Flowmeter is suitable for liquid, gas, and steam applications. The MultiVariable Vortex has all the same great features of the standard 8800D in addition to the ability to provide multiple, independent outputs and a temperature compensated mass flow output for saturated steam.

MultiVariable Vortex Applications

· Temperature compensated mass flow of saturated steam

· Temperature and volumetric flow output as independent variables for compensation in a flow computer or control system

· Volumetric flow as primary output with temperature output for use in a monitoring application (especially where it may be cost prohibitive to try to install a separate temperature sensor and transmitter)

· MultiVariable Vortex Technology Improves Custody Transfer of Saturated Steam

· We Energies Reduces Costs, Improves Performance and Reliability on Saturated Steam
