FLUXUS® F601 Technical Specification
Number of Sound Paths
The number of sound paths is the number of transits of the ultrasonic signal through the medium in the pipe.
Depending on the number of sound paths, the following methods of installation exist:
• reflect arrangement
The number of sound paths is even. Both of the transducers are mounted on the same side of the pipe.
Correct positioning of the transducers is easier.
• diagonal arrangement
The number of sound paths is odd. Both of the transducers are mounted on opposite sides of the pipe.
• direct mode
Diagonal mode with 1 sound path. This should be used in the case of a high signal attenuation by the medi-
um, pipe or coatings.
The preferred method of installation depends on the application. While increasing the number of sound paths
increases the accuracy of the measurement, signal attenuation increases as well. The optimum number of
sound paths for the parameters of the application will be determined automatically by the transmitter.
As the transducers can be mounted with the transducer mounting fixture in reflect arrangement or diagonal ar-
rangement, the number of sound paths can be adjusted optimally for the application.
