Emerson Process Management’s line of Rosemount 8800 Vortex flow meters now offers HART Protocol Revision 7, which allows for easier identification in the field, commissioning and configuration, according to the company. The Locate Device feature of HART 7 displays a visible code on the device’s LCD screen. Once connected to the device or while viewing from the control room, Long Tag allows a detailed device name to be viewed or loaded into the flow meter. Long Tag support increases the character limit from the current eight-character tag to 32 characters, allowing the user to create more accurate descriptions.
HART 7 also offers greater flexibility for device configuration, according to Emerson. For up-to-date process information, HART 7 delivers expanded burst mode capabilities to allow the vortex meter to burst up to eight variables and to trigger messages based on process events.
In addition to the latest HART 7 features, the 8800 Vortex flow meter 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.
