2.9.2 Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character FT value.
They are provided on the sensor tag.
Both values contain decimal points. During characterization, these are entered as a single 10-character string.
The 10-character string is called either
Flowcal
or
FCF
.
If your sensor tag shows the
FCF
and the
FT
values separately and you need to enter a single value,
concatenate the two values to form the single parameter value, retaining both decimal points.
Concatenating
FCF
and
FT
FCF = x.xxxx FT = y.yy Flow calibration parameter: x.xxxxy.yy
2.9.3 Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
Density calibration parameters are typically on the sensor tag and the calibration certificate.
If your sensor tag does not show a
D1
or
D2
value:
•
For
D1
, enter the Dens A or
D1
value from the calibration certificate. This value is the line-condition
density of the low-density calibration fluid. Micro Motion uses air. If you cannot find a Dens A or
D1
value,
enter
0.001
g/cm
3
.
•
For
D2
, enter the Dens B or
D2
value from the calibration certificate. This value is the line-condition density
of the high-density calibration fluid. Micro Motion uses water. If you cannot find a Dens B or
D2
value,
enter
0.998
g/cm
3
.
If your sensor tag does not show a
K1
or
K2
value:
•
For
K1
, enter the first 5 digits of the density calibration factor. In this sample tag, this value is shown as
12500.
•
For
K2
, enter the second 5 digits of the density calibration factor. In this sample tag, this value is shown as
14286.
