Table 14-4. Density of water
5. To perform the third-point density calibration, follow these steps:
a. Compare the maximum flow rate allowed by the process against
the appropriate value from
Table 14-1
. If the maximum flow rate
allowed by the process is less than the value listed in
Table 14-1
,
it is not necessary to perform the third-point (K3) calibration.
b. Fill the sensor with a process fluid that has a stable density.
