Flow Control (May 2008) 

QUIZ:   Impulse tubing that is not completely full can cause measurement error, as empty tubing runs the risk of trapping air bubbles.

The impulse tubing is routed down 25 cm (10 inches) from the taps and then up to the transmitter to form a condensate seal. What is the approximate pressure measurement error if the air is not bled out of one of the impulse tubes during calibration?  click for more...
