8.12Configuring sensor parameters

Optional Configuration

8.12Configuring 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.

8.13Configuring 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.

8.13.1About 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.
