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 flow 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 generated at the Rosemount factory during
flow calibration and is unique to each sensor and is located on the sensor tag.
PV damping
Primary variable damping allows selection of a response time, in seconds, to a step change in
flow rate. It is most often used to smooth fluctuations in output.
