Protocol expansion for flowmeters helps reduce start-up costs.

Emerson adds HART 7 to vortex flowmeters for more efficient commissioning, start-up, and configuration.

The ability to efficiently commission field devices reduces start-up costs and schedule risk for large projects. Emerson Process Management’s line of Rosemount 8800 Vortex flowmeters now offers HART® Protocol Revision 7, which allows for easier identification in the field, commissioning, and configuration.

“Making it easier to commission and start up a facility accelerates the return on our customers’ investment,” said Mark Fleigle, vice president of technology and product development for Emerson Process Management. “The extension of HART 7 to our vortex flowmeters simultaneously adds functionality and improves usability.”

Properly identifying devices both in the field and in the control room takes the guesswork out of whether or not the correct device is being configured or commissioned. The Locate Device feature of HART 7 displays a visible code on the device’s LCD screen which allows for quick field identification.

Once connected to the device, or while viewing from the control room, Long Tag allows for a detailed device name to be viewed or loaded into the flowmeter. Long Tag support increases the character limit from the current eight character tag to 32 characters, allowing the user to create more accurate descriptions necessary to track down each unique device.

HART 7 also offers greater flexibility for device configuration. For the most up to date process information, HART 7 delivers expanded burst mode capabilities to allow the vortex meter to burst up to 8 variables and to trigger messages based on process events.

In addition to the latest HART 7 features, the 8800 Vortex flowmeter now provides Sensor Signal Strength as a display and output variable. This allows for continuous health monitoring of the flow sensor both at the device and remotely as a HART variable.
