Fig. 8 Rotation bypass meter
When the bypass meter is commissioned or set into operation, bubbles of air will initially
accumulate at the top part, which must be removed. For this purpose, the union nut (fig.
9, pos. 9) must be somewhat loosened during operation and the device must be rotated
by 360°, so that the air bubbles can escape. Then the bypass meter has to be positioned
vertically and the union nut has to be tightened once again.
Before pressure test in pipes, the bypass meter has to be disassembled
and the connection of the orifice plate has to be screwed pressure-tight
with the cap.
