Required Transmitter Configuration
6.2 Characterizing the flowmeter
Characterizing the flowmeter 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.
6.2.1 When to characterize
If the transmitter and sensor were ordered together, then the flowmeter has already been
characterized. You need to characterize the flowmeter only if the transmitter and sensor are being
paired together for the first time.
6.2.2 Characterization parameters
The characterization parameters that must be configured depend on your flowmeter’s sensor type:
“T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed
in Table 6-1. The “Other” category includes all Micro Motion sensors except T-Series.
The characterization parameters are provided on the sensor tag. See Figure 6-1 for illustrations of
sensor tags.
