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:
Two-channel operation
The transmitter is able to operate two independent measuring channels (measuring channel 1 and measuring
channel 2). A pair of sensors is connected per measuring channel. Both measuring channels operate
independently of one another and are supported by the transmitter to an equal extent.
Two-channel operation can be used for the following measurements:
• Two-channel measurement = flow measurement at two separate measuring points
• Two-path measurement = redundant flow measurement at one measuring point
Two-channel measurement
The flow is measured at two separate measuring points in the case of two-channel measurement.
The measured values of the two measuring channels can be processed and displayed differently.
The following measured values can be output for two-channel measurement:
• Individual measured values per measuring channel (output independently of one another)
• The difference between the two measured values
• The sum of the two measured values
The two measuring channels can be configured individually. This makes it possible to independently configure
and select the display, outputs, sensor type and type of installation.

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 W can be too
small for two traverse installation. In this case, the 1 traverse type of installation must be used.
3)
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"), 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.
