New Novel Contactless Flow Measurement

The new measurement method has been developed in close cooperation with the University of Strasbourg. A hydraulic model perfectly adjusted to the conditions on the measurement site is the basis for accurate measurements. This model utilises two level measurements to determine the flow rate. Both levels are measured at a known distance, such as in two consecutive shafts within a channel system. The measurement accuracy is comparable to other contactless flow measurement systems such as Radar. By calibrating the measurement system even higher accuracies can be achieved. Hydraulic phenomena such as backwater and free discharge can be detected using NivuSmart Q, from Nivus (Germany), without any problems.

The system operates contactless since ultrasonic sensors are used for level measurement. Therefore costs for installation and maintenance are remarkably low. Using self-sufficient GPRS data loggers featuring very long battery lifetimes moreover allows system operation without mains power supply. Being available on a particular data portal, the data can be accessed via Internet from anywhere in the world.

NIVUS supply the new flow measurement as a complete system. Starting with the measurement site assessment, the measuring of existing channels and the installation through the implementation of the specific measurement place models as well as the measurement verification - all steps are executed solely by the system manufacturer.
