Sensor selection and arrangement
The sensors can be arranged in two ways:
• Mounting arrangement for measurement via one traverse: the sensors are located on opposite
sides of the pipe.
• Mounting arrangement for measurement via two traverses: the sensors are located on the same
side of the pipe.

Recommendations
The number of traverses required depends on th sensor type, the nominal diameter and the
thickness of the pipe wall. We recommend the following types of mounting:

1)
Prosonic Flow W
DN15 to DN65 (½" to 2½")
6 MHz
W-CL-6F
2 traverses
2)
DN 80 (3")
2 MHz
W-CL-2F
2 traverses
DN 100 to 300 (4" to 12")

1 MHz (or 2 MHz)
W-CL-1F
W-CL-2F
2 traverses
2)
DN 650 to 4000 (26" to 160")
1 MHz (or 0.5 MHz)
W-CL-1F
W-CL-05F
1 traverses
2)
1)
The installation of clamp-on sensors is principally recommended in the 2 traverse type installation. This type of
installation allows the easiest and most comfortable type of mounting. However, in certain applications a 1 traverse
installation may be preferred.
These include:
• Certain plastic pipes with wall thickness > 4 mm (0,16 in)
• Lined pipes
• Applications with fluids with high acoustic damping
2)
0.5 MHz sensors are also recommended for applications with composite material pipes such as GRP*) and may be
recommended for certain lined pipes, pipes with wall thickness >10 mm, or applications with media with high acoustic
damping. In addition, for these applications we principally recommend mounting the W sensors in a 1 traverse
configuration.
3)
6 MHz sensors for applications where flow velocity
10m/s (32.8Hz/s)
