Sliding the Ultrasonic Sensor in Place
l Double check the ultrasonic sensor to confirm that it is still level.
Surcharge Mount
The surcharge mount is a V-shaped bracket with an ultrasonic plate attachment. Its
use is limited to installations on manhole walls and not in the sewer pipe itself.
Surcharge mounts are used very infrequently but will be necessary when the flow level
is continually in the dead zone of the pipe-mounted ultrasonic sensor or when a
pressure sensor has not been installed in a site that surcharges frequently.
