The long side of the sensor must be parallel with the longitudinal
axis of the channel.

Sites where a large amount of aeration or turbulence will be
present often require the use of a secondary pressure transducer.
In these cases, the mounting of the secondary sensor, including
elevation and orientation, must also be considered.
2.6.3 Pro20: Cabling Be careful to route the cable away from the side of the sensor
where it is attached. Improper cable routing increases the possi-
bility of debris fouling.
Figure 2-27 Sensor cable direction
During installation, ensure that the cable connector end is sealed
for protection in case it comes into contact with water.
If a mounting apparatus (such as a ring or rectangular frame) is
used, cables should be fastened to its downstream side. All per-
manent installations require the cables to be secured to the
channel wall and mounting apparatus with rubber-cushioned
stainless steel loop straps at 6" (nominal) intervals.
