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 are on page 26. Descriptions of the more 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 Rate Units

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.

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.

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)

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.

Calibration Number

The sensor calibration number is a 16-digit number used to identify sensors calibrated at the Rosemount factory.
