Horizontal Installations, Self Draining

Difficult Installation Conditions
The accumulation of air or gas bubbles in the meter pipe can lead to increased inaccuracies. Some difficult
installations are shown in Fig. 10.
Installations at the highest point in the pipeline (Figure A) can result in the formation of air pockets which can
lead to appreciable inaccuracies. Another difficult installation condition is immediately upstream of a free dis-
charge (Figure B) in a drop line.
