4-34 ADS 3600 Flow Monitor O&M Manual
l Spot mark with a drill in the middle hole.
l Rotate the bracket 90
°
.
l Drill and mount the anchor bolt.
l Secure the bottom of the bracket with a washer and 7/16 in. (11 mm) anchor
bolt.
l Verify that the ultrasonic portion of the bracket is level. If it is slightly
unleveled, horizontal adjustments can be made on the bottom of the bracket by
moving the bottom portion of the bracket to the left or right (bottom mounting
holes are oval, thus allowing for minor horizontal adjustments).
l Drill and mount the anchor bolt in one of the pre-drilled holes located at the
top portion of the bracket for extra security.
l Confirm that the ultrasonic sensor is level.
3/4 Band Velocity Mount
The 3/4 band velocity mount and the 1/2 band velocity mount require almost identical
methods of construction. Only one difference exists between the designs. Because
both sides of the 3/4 band are secured to the pipe wall, the construction of the 3/4
band velocity mount usually allows for the velocity/pressure sensor to be mounted in
the center of the flow. This is not possible with the 1/2 band velocity mount.
You will need the following parts when assembling one velocity band:
l two 3 mm
×
8 mm flat-head machine screws, and
l a segment of stainless steel or aluminum special flange of site-specific length.
The special flanges come in standard 2.5 m (8 ft) lengths. If one special flange
will not reach around the pipe, attach two bands together. (If the installation is
in a square-shaped pipe, use a 2.5 m (8 ft) straight aluminum strip).
You will need the following tools when assembling one velocity band:
l a small slotted screw driver,
l diagonal cutters,
l a rotary drill,
l a 3 mm (7/32 in.) drill bit (ADS part number F35-0025), and
l a 10 mm (3/8 in.) drill bit (ADS part number F35-0023).
