CAUTION
Make sure the sensor cable is securely fastened along the
back (downstream) edge of the ring. Otherwise, the sensor
may provide
inaccurate level readings under conditions of
high velocity.
Do not overtighten the plastic cable ties; they should be tight-
ened just enough to secure the cable in place, without greatly
indenting the cable. Overtightening the plastic ties may col-
lapse the reference tube in the cable, blocking it.
