Emerson Process Management 1500 manual Characterizing the flowmeter, When to characterize

Required Transmitter Configuration

4.2Characterizing 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.

4.2.1When to characterize

If the transmitter, core processor, and sensor were ordered together, then the flowmeter has already been characterized. You need to characterize the flowmeter only if the core processor and sensor are being paired together for the first time.

4.2.2Characterization 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 4-1.The “Other” category includes all Micro Motion sensors except T-Series.

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 4-2and 4-3 for illustrations of newer and older sensor tags.
