Traditionally the transit time method is used in full pipes.
In the case of fully developed velocity profiles it is sufficient to use a single path measurement (1E1P).
We normally encounter distorted flow profiles however which have negative effects on the measurement accuracy.
These effects can be compensated by using up to 8 measurement paths.
This enables the NivuSonic to achieve the highest accuracy even in difficult applications. Measurement in open channels and rivers makes high demands on the measurement technology used.
Undefined cross-sectional profiles or flowing river bottoms represent conditions which complicate the use of standard measurement technology. With the NivuSonic in combination with other measurement units NIVUS is able to implement many of these applications. In the case of the level and sludge level measurements required, NIVUS is able to access measurement systems which have been proven for many years. Known as state of the art, the easy handling of uncommon profiles was transferred from OCM Pro to NivuSonic.
The number of measurement paths useable will increase measurement accuracy the way it does in full pipes. Up to 8 measurement paths are available for use in open channels as well. The NivuSonic implements their positions and weighting according to DIN EN 6416 standards.
