Sensor selection and arrangement

The sensors can be arranged differently:
• 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.

The number of traverses required depends on the sensor type, the nominal diameter and the
thickness of the pipe wall. We recommend the following types of mounting:
Sensor Type Nominal Diameter
DN 15 to 65 (½ to 2½")
DN 50 to 65 (2 to 2½")
DN 80 (3")
Prosonic Flow P
DN 100 to 300 (4 to 12")
DN 300 to 600 (12 to 24")
DN 650 to 4000 (26 to 160")
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 and means that a system can also be mounted
even if the pipe can only be accessed from one side. However, in certain applications a 1 traverse installation may be
preferred. These include:
• Certain plastic pipes with wall thickness > 4 mm (0.16")
• Pipes made of composite materials such as GRP
• Lined pipes
• Applications with fluids with high acoustic damping
2)
If the pipe nominal diameter is small (DN 65 / 2½" and smaller), the sensor spacing with Prosonic Flow P can be too
small for two traverse installation using sensor P-CL-2F*. In this case, the 1 traverse type of installation must be used.
3)
0.5 MHz sensors (Prosonic Flow W) 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 (0.4"), 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.
4)
6 MHz sensors for applications with flow velocity < 10 m/s.
