Dynasonics Fusion Water Flow Meter - Manual (Page 10)

10
For best measurement accuracy and reading stability, mount the
meter with the minimum lengths of straight pipe described in
Figure 4. The optimum straight pipe diameter recommendations
apply to pipes in both horizontal and vertical orientation.
Note: If adequate straight plumbing
cannot be provided, the FUSION will
operate repeatably and reliably, but
will not achieve optimum accuracy.
Outdoor Installations
In outdoor installations, mount
the flow meter with the display/
keypad facing 9-10 o'clock to
prevent water from collecting in
the keypad recess and water
running down the cables to the
conduit connections. Refer to
FIGURE 5.
