Sensor Installation and Connection 5-45
Note: When positioning the special mounting metal,
ADS recommends reserving the left side of the pipe for the
long end of the ¾-band (end extending almost completely
up one side of the pipe) and the ¼-band for routing the
sensor cable and accommodating the Silt Mount Adapter
(when necessary). The AV|Gated, AV|Max and Peak
Combo Sensors may be offset up to 30 degrees (7:00) up
the left side of the pipe to account for silt with the use of
the Silt Mount Adapter (ADS p/n 8000-0271).
¾-Band Mount
Perform the following procedure to mount the Peak Combo or
AV|Gated sensor (when applicable) in a pipe using the ¾-band
mount:
1. Use a hacksaw to cut the band to the appropriate length. Cut
the band so that, once installed, it will run approximately ¾ of
the circumference of the pipe.
2. Locate the sensor at a position on the band based on installing
the long end of the band (end extending almost completely up
one side of the pipe) on the left side of the incoming pipe
(upstream from the manhaole) and the existence of silt at the
bottom of the pipe. ADS recommends reserving the left side of
the pipe for the long end of the band to accommodate the
sensor cable and a silt mount adapter, when applicable.
AV|Gated, AV|Max, or Peak Combo in pipes with no silt,
locate the sensor on the band so the sensor is located at the
bottom center of the pipe once installed. (The AV|Gated
must be installed no more than +/- 5 degrees from the
bottom center of the pipe.)
In pipes with silt present, locate the sensor slightly up the
long end (left side) of the band so the sensor is above the
silt level once installed. However, make sure it will not be
more than 30 degrees from the bottom center of the pipe
(7:00 position).
