Quick Start Guide
Step 7: Basic configuration
Once the magnetic flowmeter is installed and power has been supplied, the
transmitter must be configured through the basic setup. These parameters can
be configured through either a local operator interface or a HART communication
device. A table of all the parameters begins on
advanced functions are included in the comprehensive product manual.
Basic setup
Tag
Tag is the quickest and shortest way of identifying and distinguishing between
transmitters. Transmitters can be tagged according to the requirements of your
application. The tag may be up to eight characters long.
Flow units (PV)
The flow rate units variable specifies the format in which the flow rate will be
displayed. Units should be selected to meet your particular metering needs.
URV (Upper Range Value)
The upper range value (URV) sets the 20 mA point for the analog output. This
value is typically set to full-scale flow. The units that appear will be the same as
those selected under the units parameter. The URV may be set between
–39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s)
span between the URV and LRV.
LRV (Lower Range Value)
Reset the lower range value (LRV) sets the 4 mA point for the analog output. This
value is typically set to zero flow. The units that appear will be the same as those
selected under the units parameter. The LRV may be set between
–39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s)
span between the URV and LRV.
Line size
The line size (sensor size) must be set to match the actual sensor connected to the
transmitter. The size must be specified in inches.
Calibration number
The sensor calibration number is a 16-digit number generated at the Rosemount
factory during flow calibration and is unique to each sensor.
Local operator interface
To activate the optional Local Operator Interface (LOI), press the DOWN arrow
two times. Use the UP, DOWN, LEFT, and RIGHT arrows to navigate the menu
structure. The display can be locked to prevent unintentional configuration
changed. The display lock can be activated through a HART communication
device, or by holding the UP arrow for 10 seconds. When the display lock is
activated, DL will appear in the lower right hand corner of the display. To
deactivate the display lock (DL), hold the UP arrow for 10 seconds. Once
deactivated, the DL will no longer appear in the lower right hand corner of the
display.
