Configure The Petroleum Measurement Application - Emerson Micro Motion 9739 MVD Configuration And Use Manual

• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement
because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time
between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. Valid values for Temperature
Damping are 0, 0.6, 1.2, 2.4, 4.8, 9.6, 19.2, and 38.4.
4.6.3 Effect of Temperature Damping on process measurement
Temperature Damping affects all processes and algorithms that use temperature data from the internal
sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of temperature on
the sensor tubes.
Petroleum measurement
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.
Concentration measurement
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.
4.6.4 Configure Temperature Input
Temperature data from the on-board temperature sensor (RTD) is always available. Optionally, you can set up
an external temperature device and use external temperature data.
Procedure
Choose Device Tools → Configuration → Process Measurement → Temperature → Source.

4.7 Configure the petroleum measurement application

The petroleum measurement application corrects line density to reference temperature according to
American Petroleum Institute (API) standards. The resulting process variable is referred density.
4.7.1 Configure petroleum measurement using ProLink III
The petroleum measurement parameters specify the API table, measurement units, and reference values to
be used in referred density calculations.
Prerequisites
You will need API documentation for the API table that you select.
