Witryna26 wrz 2010 · Impulse tubing that is not completely full can cause measurement error, as empty tubing runs the risk of trapping air bubbles. In one installation, the transmitter taps in a two bar steam flow measurement system are located at the same elevation as the flowmeter taps. The impulse tubing is routed down 25 cm (10 inches) from the … Witryna26 wrz 2010 · API RP 551 recommends a maximum impulse line length of 20ft (6m). The drain pot volume can equate to a significant length of impulse line. A two-inch nominal diameter drain pot made from schedule 80 SS pipe represents, per foot, the rough equivalent volume of 20ft of ½" OD, 0.049-inch wall SS tubing. Liquid Flow …
