Configuration
To configure the temperature measurement unit:
• Using the Communicator, select
Detailed Setup > Config Fld Dev Var > Temperature.
• Using ProLink II, click
ProLink > Configuration > Temperature.
• Using the display, see Figure 2-13.
4.8.2 Temperature damping
Before configuring temperature damping, review the information in Section 4.10.
Configuration
To configure temperature damping:
• Using the Communicator, select
Detailed Setup > Config Fld Dev Var > Temperature.
• Using ProLink II, click
ProLink > Configuration > Temperature.
Note: You cannot configure temperature damping with the display.
4.9 Configuring pressure compensation
The Model 2200S transmitter can compensate for the effect of pressure on the sensor flow tubes.
Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure
change away from calibration pressure.
Note: Pressure compensation is optional. Perform this procedure only if required by your application.
The Model 2200S transmitter supports only static pressure compensation; i.e., the external pressure is
a known static value.
4.9.1 Pressure correction factors
When configuring pressure compensation, you must provide the flow calibration pressure – the
pressure at which the sensor was calibrated (which therefore defines the pressure at which there will
be no effect on the calibration factor). Enter 20 PSI unless the calibration document for your sensor
indicates a different calibration pressure.
Two additional pressure correction factors may be configured: one for flow and one for density. These
are defined as follows:
• Flow factor – the percent change in the flow rate per psi
• Density factor – the change in fluid density, in g/cm
