Transmitter Configuration, Characterization, and Calibration

Characterizing the meter

Characterizing the meter adjusts the transmitter to compensate for the unique traits of the sensor it is
paired with. The characterization parameters, or calibration parameters, describe the sensor's
sensitivity to flow, density, and temperature.
5.4.1

When to characterize

If the transmitter and the sensor were ordered together as a Coriolis meter, then the meter has already
been characterized. You need to characterize the meter only if the transmitter and the sensor are being
paired together for the first time.
5.4.2

Characterization parameters

The characterization parameters that must be configured depend on your meter's sensor type:
"T-Series" or "Other" (also referred to as "Straight Tube" and "Curved Tube," respectively), as listed
in Table 5-1. The "Other" category includes all Micro Motion sensors except T-Series. Table 5-1 also
shows the location of each parameter within ProLink II.
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 Figures 5-2 and 5-3 for illustrations of newer and
older sensor tags.
