Sensor Installation and Connection 3-63
14. Drill and mount a ¼-inch x 2 ¼-inch (M6 x 55-mm) anchor
bolt in one of the other pre-drilled holes at the top portion of
the bracket for extra security.
15. Confirm that the sensor is level. To protect the crystals on the
sensor, use a block of wood of uniform dimensions between the
level and the horizontal portion of the sensor!
16. Measure the physical offset for the sensor (the distance from
the crown (top) of the pipe to the face of the sensor). Enter this
distance as a negative value. For example, if it is 24 inches
(610 mm) from the top of the pipe to the face of the sensor in
the manhole, you would enter -24 inches (-610 mm) for the
physical offset.
Note: This value will be necessary when configuring the
monitor using the Qstart software.
