AV|Gated Sensor
Mount the sensor as close as possible to
the six o’clock position (bottom). The sensor must be within
+/- 5 degrees of the bottom center of the pipe . AV|Gated
sensors should not be installed in pipes with silt. If necessary, a
Silt Mount Adapter can be used to mount the sensor 30 degrees
up the left of the pipe (the 7:00 position) when a higher
elevation is necessary. However, keep in mind that a physical
offset measurement must be taken when mounting the sensor in
any position outside the bottom of the pipe. Refer to
Installing
the Ring in the Pipe on page 5-28
z
AV|Max Sensor Mount the sensor as close as possible to the
six o’clock position (bottom), provided it is mounted above the
level of any silt present at the bottom of the pipe. Any silt
covering the sensor could interfere with the sensor signals,
potentially producing inaccurate or erroneous readings.
To avoid silt, the AV|Max sensor can be rotated as much as 15
degrees up left side of the pipe without using a special
mounting device. A
Silt Mount Adapter can be used to mount
the AV|Max sensor 30 degrees up the left side of the pipe (the
7:00 position) when a higher elevation is necessary. However,
keep in mind that a physical offset measurement must be taken
when mounting the sensor in any position outside the bottom
of the pipe. Refer to
Installing the Ring in the Pipe on page 5-
28.
z
Peak Combo Sensor Mount the sensor as close as possible
to the six o’clock position (bottom), provided it is mounted
above the level of any silt present at the bottom of the pipe.
Any silt covering the sensor could interfere with the sensor
signals, potentially producing inaccurate or erroneous readings.
A Silt Mount Adapter can be used to mount the sensor 30
degrees up the left side of the pipe (7:00 position) when a
higher elevation is necessary. However, keep in mind that a
