Overview
Characterizing the flowmeter adjusts your transmitter to match the unique traits of the
sensor it is paired with. The characterization parameters (also called calibration
parameters) describe the sensor’s sensitivity to flow, density, and temperature.
Depending on your sensor type, different parameters are required. Values for your sensor
are provided by Micro Motion on the sensor tag or the calibration certificate.
Tip
If your flowmeter was ordered as a unit, it has already been characterized at the factory. However,
you should still verify the characterization parameters.
Procedure
1.
Specify Sensor Type.
• Straight-tube (T-Series)
• Curved-tube (all sensors except T-Series)
2. Set the flow characterization parameters. Be sure to include all decimal points.
• For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and FFQ.
• For curved-tube sensors, set Flow Cal (Flow Calibration Factor).
3. Set the density characterization parameters.
• For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2.
• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown
as DT.)
2.4.1 Sources and formats for characterization parameters
Different sensor tags display characterization parameters differently. On older sensors, the
sensor tag may not contain all the required parameters.
