The value you enter is automaticaly rounded down to the nearest valid value. Valid values
for Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 76.8.
Effect of Temperature Damping on process measurement
Temperature Damping affects the response speed for temperature compensation with
fluctuating temperatures. Temperature compensation adjusts the process measurement
to compensate for the effect of temperature on the sensor tube.
Temperature Damping affects petroleum measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for petroleum measurement, Temperature Damping does not
affect petroleum measurement process variables.
Temperature Damping affects concentration measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for concentration measurement, Temperature Damping does not
affect concentration measurement process variables.
4.7 Configure the petroleum measurement
application
The petroleum measurement application enables Correction for the effect of Temperature
on the volume of Liquids (CTL), by calculating and applying a Volume Correction Factor
(VCF) to volume measurement. Internal calculations are performed in compliance with
American Petroleum Institute (API) standards.
4.7.1
Configure petroleum measurement using ProLink II
1. Choose ProLink > Configuration > API Setup.
2. Specify the API table to use.
a. In API Chapter 11.1 Table Type, select the API table group.
b. In Units, select the the measurement units you want to use.
These two parameters uniquely specify the API table.
3. If your API table is 53A, 53B, 53D, or 54C, set Reference Temperature to the appropriate
value for your application. Enter the value in °C.
4. If your API table is 6C, 24C, or 54C, set Thermal Expansion Coefficient to the appropriate
value for your application.
5. Determine how the transmitter will obtain temperature data for the petroleum
measurement calculations, and perform the required setup.
