Sensor Selection And Arrangement - Endress+Hauser Proline Prosonic Flow 91W Technical Information

Proline Prosonic Flow 91W
Sensor selection and
arrangement
Endress+Hauser
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 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 2 ½")
DN 80 (3")
DN 100 to 300 (4" to 12")
Prosonic Flow W
DN 300 to 600 (12" to 24")
DN 650 to 2000 (26" to 80")
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:
• 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 (0.4 in), 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 are recommended for applications where flow velocity is < 10 m/s (32.8 Hz/s)
