Mounting the Pressure Depth Sensor
Two special installation methods are available for mounting the
pressure depth sensor:
 ¾-band mount
 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 pressure depth 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 sensor.
However, a ½-band mount may be appropriate for monitoring under
the following circumstances:
 Large pipes with deep minimum flows
 Large pipes with excessive silt present
