Description

Emerson-Rosemount 8800 Multi Variable Vortex Flow Meter

Features:

♦ The capacity to compensate for temperature and pressure allows for the measurement of steam & liquid mass flow without the use of a flow computer.

♦ Without the use of a separate temperature sensor or external thermowell, the integrated temperature sensor enables reliable temperature measurement.

♦ Superheat Diagnostics aids in the detection of liquid applications for superheated steam deterioration.

♦ Use up to five user-defined temperature and density pairs to compensate for any liquid flow.

♦ The 4-20 mA digital or pulse output can be used to assign flow and temperature variables, allowing for more sophisticated monitoring possibilities.

♦ The unique, gasket-free meter body design eliminates potential leak points, increasing plant availability and decreasing maintenance costs.

♦ A higher level of safety assurance is provided by the CriticalProcess valve (CPA option), which enables users to check the integrity of

secondary containment.

♦ Vibration immunity is achieved using a mass-balanced sensor and Adaptive Digital Signal Processing with visual filtering.
