3.3.5 IMPORTANT GUIDELINES FOR
CORRECT INSTALLATION
For a correct working condition please follow
the important guidelines shown in the following
figures. Improper installation result in inaccurate
measurement.
To achieve the most accurate flow measurement
it is essential to have minimum straight lengths
of the inlet and outlet pipes as shown (DN: sensor
nominal diameter)
• For partially filled pipes or pipes with downward
flow and free outlet, the flow meter should be
located in a U-tube, respecting the upward and
downward lengths between the curves.
• In the case of T-connection between two
different tubes, please keep a 10DN distance
upstream of the flow meter.
• Keep 5 meters between the axis of the flow
meter and those of the gate valve placed
downstream.
