Incorrect installations will cause the
rotor weight to be felt on the bottom of
the measuring cavity.
6.2 Orientation
When installing the flowmeter, orientation must be considered. The rotor shafts
must be in a horizontal plane. To verify that the rotor shafts are in a horizontal
plane, electronic cover or optional digital display will be facing in a horizontal
direction. For modification in the field, the electronic cover or digital display can be
rotated in any 90 degree position. This accommodates access to the electrical entry
and allows the electronic display orientation to best suit the installation.
The DON flowmeter accommodates both horizontal and vertical flows. It is
recommended that for vertical flow installations that the liquid flow up through the
meter
(i.e. bottom to top ). This orientation assists in air or entrained gas removal.
The flow meter is bidirectional. To identify the flow direction, in which the flowmeter
was calibrated, the flowmeters are marked with arrows. These arrows are placed
on the lower side for models DON-x04 .. DON-x15 and on the top side for models
DON x20..DON-x60. The flowmeter calibration data refers to this arrow direction.
This is also the preferred flow direction.

Note: orient the conduit entry downward
to avoid moisture migration into the
electronic cavity.
