8.12 Configuring sensor parameters
The sensor parameters are used to describe the sensor component of your flowmeter. They are not
used in transmitter processing, and are not required. The following sensor parameters can be changed:
• Serial number (can be set only once)
• Sensor material
• Sensor liner material
• Sensor flange type
To configure sensor parameters:
• Using ProLink II, see Figure B-2.
• Using a DeviceNet tool, see Table C-8.
Note: This functionality is not available via the display menus.
8.13 Configuring the petroleum measurement application
The API parameters determine the values that will be used in API-related calculations. The API
parameters are available only if the petroleum measurement application is enabled on your
transmitter.
Note: The petroleum measurement application requires liquid volume measurement units. If you plan
to use API process variables, ensure that liquid volume flow measurement is specified. See
Section 8.2.
8.13.1 About the petroleum measurement application
Some applications that measure liquid volume flow or liquid density are particularly sensitive to
temperature factors, and must comply with American Petroleum Institute (API) standards for
measurement. The petroleum measurement enables Correction of Temperature on volume of Liquids,
or CTL.
Terms and definitions
The following terms and definitions are relevant to the petroleum measurement application:
• API – American Petroleum Institute
• CTL – Correction of Temperature on volume of Liquids. The CTL value is used to calculate
the VCF value
• TEC – Thermal Expansion Coefficient
• VCF – Volume Correction Factor. The correction factor to be applied to volume process
variables. VCF can be calculated after CTL is derived
CTL derivation methods
There are two derivation methods for CTL:
• Method 1 is based on observed density and observed temperature.
• Method 2 is based on a user-supplied reference density (or thermal expansion coefficient, in
some cases) and observed temperature.
