Functional description
12 Operating Ranges
The NivuFlow 600 Mobile is a portable measurement system for flow measurement. The
instrument is designed mainly for measurement in slightly polluted to clear aqueous media of
various compositions.
It is used in full pipes and rectangular geometries with different dimensions.
NivuFlow Mobile 600 with clamp-on sensors is a contactless measurement system and hence
is independent from pressure. Clamp-on measurement systems are suitable only for full pipes.
An overview on connectable sensors can be found in chapter „9.2 Connectable Sensors“.
Using multiple sensor pairs in a common measurement place will increase the accuracy of flow
velocity detection.
Note
The measurement method used to determine the flow velocity is based on the transit
time difference principle. It is indispensable for the system functionality to have as little
interfering particles (dirt particles, gas bubbles and similar) as possible within the medium.
Such particles scatter or damp the ultrasonic signal and hence may possibly prevent the
measurement.
The signal is severely reduced as soon as there are too many particles prevailing in the
medium. This may lead to faulty or incorrect results.
