Emerson Process Management introduces the Rosemount 8800D CriticalProcess Vortex flowmeter. This flowmeter enhances online vortex sensor maintainability, while providing an added level of safety on critical applications. The vortex sensor in the Rosemount 8800D is isolated from the process, making it possible to maintain the sensor without requiring a process shutdown, greatly increasing process availability. The CriticalProcess Vortex’s ability to ensure the vortex sensor is isolated from the process enhances safety by limiting personnel exposure, and maximises product throughput by eliminating the need to shutdown the process to maintain a vortex sensor. In addition to the ability to maintain the vortex sensor online, the Rosemount 8800D can verify the health of the transmitter by simulating the vortex flow signal. The combination of these two features enables complete verification of the electrical components of the flowmeter while the process is up and running.
