8.1 Overview
The Characterize Sensor dialog box contains text boxes for entry of
factors that describe sensor sensitivity to flow and density.
The flow calibration factor describes a particular sensor's sensitivity
to flow.
Density factors describe a particular sensor's sensitivity to density.
Slug flow limits set the density at which flow outputs indicate zero
flow due to slug flow (slugs of gas in a liquid flow stream).
For RFT9739 transmitters, the ProLink program also supports entry of
factors used for calculating temperature and pressure.
The temperature calibration factor describes the slope and offset of
the equation used for calculating temperature.
The viscosity calibration factor describes the slope or the slope and
offset of the equation used for calculating viscosity.
For a Version 2 or later model RFT9739, the pressure compensation
parameters compensate for the pressure effect on sensor flow tubes.
CAUTION
Failure to set control devices for manual operation
before characterization could cause transmitter
output error.
Before opening the File, Configure, Calibrate, or
Applications menus, set process control devices for
manual operation.
Whenever a dialog box such as the one depicted
below appears, isolate the transmitter from devices
that used transmitter outputs for process control, then
choose Yes.
