Integrate the pipe length so that the direction of flow (1) and the
marking arrow (2) show in the same direction.
In case of disturbances at the inflow side additional baffled pipes (B)
are recommended:
90° elbow
two 90° elbows, one plane
two 90° elbows, two planes
valve, slide
Mounting position:
• Permitted mounting positions: pipe length vertical, any position
(fig. 1, 2), pipe length horizontal, unit vertical (fig. 3, 4), unit on
side, pipe length left (fig. 5).
• Avoid the mounting position shown in fig. 6 (unit on side, pipe
length right). If the flow rate is low, the specified measurement
accuracy cannot be adhered to.
