Filling Calibration Column, Continued…
Filling the Calibration Column on a skid without a cross-connect will likely require filling through the
top of the Calibration Column.
For systems with flooded suction
(see Figure 3, Page 7):
1. Open Column Isolation Valve
2. Liquid level in the column should rise to the
level in the suction source. This may be
higher than the top of the column, so prevent
overfill by closing the Column Isolation Valve
when the liquid level in the Calibration
Column reaches slightly above the top scale
mark.
3. If the liquid level in the suction source is
lower than the top scale mark, close the
Column Isolation Valve and add liquid
through the top of the column to a point
slightly above the top scale mark.
For systems on suction lift (see Figure 4, Page 8):
1. Partially fill the Calibration Column through the top.
2. Open the Column Isolation Valve briefly to vent any air that may be present in the suction
header piping. Close the Column Isolation Valve.
3. Fill the Calibration Column to slightly above the top scale mark.
Calibration Column is filled and ready for the calibration procedure.
