13. Measure the physical offset for the ultrasonic depth sensor (the
distance from the crown (top) of the pipe to the face of the
sensor).
Note: This value will be necessary when configuring the
monitor using the Profile software.
Surcharge Mount
For a site that may experience surcharge conditions, mount the
ultrasonic depth sensor on the manhole wall using a special
surcharge bracket (ADS p/n I40-0010) directly above the opening
of the incoming pipe. This will ensure the sensor measures the range
above the flow surface at the location the flow enters the manhole.
Mount the ultrasonic depth sensor in the following way:
Note: Handle the ultrasonic depth sensor with care, and
do not expose it to extreme temperatures for an extended
period of time. Keep the sensor in its protective packaging
until it is time for installation.
1. Determine the appropriate height at which to mount the
ultrasonic depth sensor portion of the surcharge bracket (The
sensor slides into the grooves of the mounting plate at the
lower portion of the bracket.) When making this
determination, keep in mind that the maximum range of the
sensor is 12.5 feet (3.8 m).
