l Step on the band to determine if any play is present.
Note: If the band is not completely flush, locate the pre-drilled hole closest to
the sensor. This is rather difficult as you will have to use the touch and feel
method. Once located, use a compressor drill or a 60 cm (24 in.) extended bit
and drill another anchor bolt hole under the flow surface. Secure the anchor
bolt to the pipe and attach the band with a 7/16 in. (11 mm) nut and
corresponding washer.
l Mold the long end of the band up the pipe wall.
l Secure the band with anchor bolts up the pipe wall every 60 cm (24 in.) until
the end of the band is reached.
Note: Ensure the sensor cable is not between the band and pipe during the
installation, or cable damage could result.
l Cable tie the velocity sensor to the ultrasonic cable and secure with the anchor
bolt at the crown (soffit) of the pipe.

l Anchor the bolt and secure the sensor cables every 60 cm (24 in.) along the
pipe crown (soffit) until the invert has been reached.
l Cut the excess portion of the cable tie.
Note: If the pipe is large and the velocity sensor cable is not run to the apex
of the pipe, then attach the velocity cable to 13 mm (1/2 in.) PVC tubing that
