When insta
lling at the “U” tube, install the meter at the lowest position, because the pipe
may accumulate air in the high place, causing the meter to be inaccurate or not
measurement. (Shown in Figure D).
Figure (D)
When the meter is installed at the elbow, it must be ensured that the distance between the
front straight pipe is ≥5 pipe diameter and the rear straight pipe is ≥3 pipe diameter.
Otherwise, the meter may not be measurement (as shown in Figure E).
Figure (E)
When installing valves or other objects in front of the meter, it must be ensured that there is
a distance of ≥ 5 times the diameter between the meter and the object, otherwise the meter
may not be metered; (as shown in Figure F).
