Sensor Installation and Connection 3-35
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:

Large pipes with deep minimum flows

Large pipes with excessive silt present
½- (left) and ¾-band (right) mounts
¾-Band Mount
Perform the following procedure to mount the Doppler velocity
sensor and pressure depth 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, when installed, it will run approximately ¾ of the
length around the inside of the pipe.
Note: The metal bands come in 8-foot lengths. Some
larger pipes may require attaching two bands together. In
addition, for square-shaped pipes, use a 8-foot straight
metal strip.
