Sensor Installation and Connection 3-29
Mounting the Ultrasonic Depth Sensor
Two special installation methods are available for mounting the
ultrasonic depth sensor:
 Standard Ultrasonic Mount
This option, the most common
method employed today, is used for mounting the ultrasonic
depth sensor in the pipe during special installations.
 Surcharge Mount
This option primarily is used for
mounting a ultrasonic depth sensor in a manhole at a site where
the flow continually occurs within 2 inches of the top of the
pipe or a site at which a pressure sensor is not available and
surcharges
frequently occur. Surcharges are conditions where
the flow completely fills the pipe and extends up into the
manhole.
Standard Ultrasonic Mount
Mount the ultrasonic depth sensor using this method 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. Position the sliding ultrasonic plate in the center apex of the
pipe, and scribe a mark on both sides of the ultrasonic plate.
2. Center the 12-inch mounting band, allowing the band to extend
about 4 inches beyond each side of the scribed location.
3. Conform one end of the curved band to the pipe configuration,
and spot drill to mark the bolt location.
4. Remove the curved band, drill an anchor bolt hole, and gently
tap a ¼-inch x 2 ¼-inch anchor bolt into the hole.
5. Mount the curved band to the anchor bolt through the pre-
drilled hole on the band, and hand-tighten a nut with washer to
the anchor bolt to secure the band.
