Mounting AV|Gated, AV|Max or Peak Combo
Sensors
Note: Regardless of which band is used to install the
AV|Gated sensor, it must be installed no more than +/- 5
degrees from the bottom center of the pipe. If further
rotation is necessary, use a Silt Mount Adapter which will
allow the sensor to be rotated 30 degrees from center (7:00
position).
Two special installation methods are available for mounting these
sensors.:
z
¾-band mount
z
½-band mount
Both mounts require almost identical installation methods. The
only significant differences are that the ¾-band mount allows the
installer to secure the band to
both sides of the pipe wall and to
position the sensor at the bottom center of the pipe. These options
are not possible using the ½-band mount. Therefore, the ¾-band
mount is the preferable method for mounting the sensors.
However, a ½-band mount may be appropriate for monitoring
under the following circumstances:
z
Large pipes with deep minimum flows
z
Large pipes with excessive silt present
