Emerson Rosemount 8782 - Chapter 5 Basic Configuration; Basic Setup

5 Basic Configuration
Once the flow meter is installed and power has been supplied, the transmitter must be
configured using the LOI, if equipped, or a configuration tool, such as ProLink III Software.
Descriptions of more advanced functions are included in Advanced Configuration
Functionality.
5.1 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 transmitter supports the 8 character Tag and the 32 character Long Tag.
Both parameters are available for configuration.
Calibration number
The sensor calibration number is a 16-digit number generated at the factory during flow
calibration, is unique to each sensor, and is located on the sensor nameplate.
Flow units (PV)
The flow units variable specifies the format in which the flow rate will be displayed. Units
should be selected to meet your particular metering needs. See Measurement units.
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.
Upper range value (URV)
The 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 flow units
parameter. The URV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12m/s). There
must be at least 1 ft/s (0.3 m/s) span between the URV and LRV.
Note
If entering a negative number, the minus sign must be entered in the furthest left position
on the LOI.
Lower range value (LRV)
The 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 flow units parameter.
The LRV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12m/s). There must be at
least 1 ft/s (0.3 m/s) span between the URV and LRV.
Note
If entering a negative number, the minus sign must be entered in the furthest left position
on the LOI.
