Ring, Sensor, and Special Installations 4-39
l This mounting method uses a special flat strip of rigid aluminum instead of the
standard band. It is stronger and is less likely to become damaged during high
flow conditions.
l It is imperative that the ring (below the water's surface) be secured with an
anchor bolt and placed within 25 to 75 mm (1 to 3 in.) of the velocity sensor.
This will prevent the velocity sensor from becoming clogged should debris
accumulate between the pipe and the metal band.

Installation
l Position the sensor portion of the band in the flow, below minimum flow levels
and out of silt.
l Orient the band in a fashion that allows one of the pre-drilled holes to be right
at the water surface.
l Spot mark with a drill.
l Drill and mount the anchor bolt to the pipe wall.
l Attach the band to the anchor bolt with a washer and a 7/16 in. (11 mm) nut.
l Position the submerged portion of the band until it is flush with the bottom of
the pipe. A slight downward bend of the band right below the water surface
may aid in ensuring that the band and sensors are flush.
