Rosemount 8800D CriticalProcess vortex flowmeter, a new offering to the vortex flowmeter family, is designed to increase plant availability and enhance overall safety. The vortex sensor is isolated from the process, allowing users to verify the performance of the sensor while providing an added level of safety on critical applications. The vortex sensor in the 8800D CriticalProcess vortex flowmeter makes it possible to verify the performance of the sensor without requiring a process shutdown, greatly increasing process availability.
