Table 14-2. Density of air
4. To perform the high-density calibration:
a. Fill the sensor with a high-density fluid, such as water.
b. If possible, shut off the flow. Otherwise, pump the fluid through
the sensor at the lowest flow rate allowed by the process. The
rate must be less than the flow rate listed in
Table 14-3
, or the
calibration will be in error. To ensure stable density, make sure the
fluid in the flow tubes remains completely free of gas bubbles
during the calibration.
