Flow calibration values
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character
FT value. Both values contain decimal points. During characterization, these are entered as a single
10-character string that includes two decimal points.
To obtain the required value:
• For older T-Series sensors, concatenate the FCF value and the FT value from the sensor tag, as
shown below.
• For newer T-Series sensors, the 10-character string is represented on the sensor tag as the FCF
value. The value should be entered exactly as shown, including the decimal points. No
concatenation is required.
• For all other sensors, the 10-character string is represented on the sensor tag as the Flow Cal
value. The value should be entered exactly as shown, including the decimal points. No
concatenation is required.
Other calibration values
Temperature calibration factors are described in Table 7-12.
Meter factors allow you to modify the transmitter’s output so that it matches an external measurement
standard. See Chapter 21 for more information.
All other values are configured exactly as they are shown on the sensor tag. Note the following:
• D3 and D4 density factors are used only if a D3 or D4 density calibration has been performed
in the field (see Section 21.5).
• K3 and K4 factors represent the calibration values at D3 and D4 respectively, and are
configured only when the D3 and D4 density factors are configured.

Variable
T-Series sensors Other sensors Default Description
Temperature slope Temp cal
(first 7 characters)
1.000000 • This value represents the temperature slope. The default
value is used for most applications. If you perform a
temperature calibration, this value is updated
automatically.
• To perform a temperature calibration, see Section 21.6.
Contact Micro Motion customer service before performing
a temperature calibration.
Temperature offset Temp cal
(last 6 characters)
0.000000 • This value represents the temperature offset. The default
value is used for most applications. If you perform a
temperature calibration, this value is updated
automatically.
• To perform a temperature calibration, see Section 21.6.
