5.5 Special topics in configuring the core interface
This section provides additional information on characterizing the Model 3711, configuring damping,
calculating and configuring meter factors, and configuring slug flow.
5.5.1 Characterization
Characterizing the meter adjusts the Model 3711 to compensate for the unique traits of the sensor it is
paired with. The characterization parameters describe the sensor’s sensitivity to flow and density.
If the Model 3711, core processor, and sensor were ordered together, then the meter has already been
characterized. You need to characterize the meter only if the core processor and sensor are being
paired together for the first time.
The characterization parameters are provided on the sensor tag. The format of the sensor tag varies
depending on your sensor’s date of purchase. See Figure 5-5 for illustrations of newer and older
sensor tags.
Figure 5-5 Sample calibration tags
Density calibration factors
If your sensor tag does not show a D1 or D2 value:
• For D1, enter the Dens A or D1 value from the calibration certificate. This value is the
line-condition density of the low-density calibration fluid. Micro Motion uses air.
• For D2, enter the Dens B or D2 value from the calibration certificate. This value is the
line-condition density of the high-density calibration fluid. Micro Motion uses water.
If your sensor tag does not show a K1 or K2 value:
• For K1, enter the first 5 digits of the density calibration factor. In the sample tag in Figure 5-5,
this value is shown as
12500
.
• For K2, enter the second 5 digits of the density calibration factor. In the sample tag in
Figure 5-5, this value is shown as
14286
.
If your sensor tag does not show an FD value, contact Micro Motion customer service.
If your sensor tag does not show a DTC or TC value, enter the last 3 digits of the density calibration
factor. In the sample tag in Figure 5-5, this value is shown as
4.44
.
