3.3.3.3 One (1) Cross Mounting Installation for 20 Series Transducer
One (1) cross mount is recommended when 100% signal strength from two (2) or four (4) cross is not met. Typically, one
(1) cross is used for older, large pipes that have built up corrosion within the pipe walls.
1. Once the installation site selection process described in section 3.2 is complete, prepare the pipe as described in 3.3.3.1.
IMPORTANT NOTE
One (1) cross mode mounting requires that transducers be installed on opposite sides of the pipe. For horizontal
pipes, the transducers should be located at the 3 o’clock and 9 o’clock positions.
2. Attach the alignment and spacer tool to one of the mounting brackets at the reference mark on the ruler.
3. Position the mounting bracket and an alignment and spacer tool in the center of the cleaned area and secure it in place
ensure that the bracket remains centered on the pipe.
The bracket is centered on the pipe when the bottom edges of both stainless side plates on the bracket are in full
angle is correct.
