Possible Applications In Heavily, Medium Or Slightly Polluted

NIVUS products are used in a large number of applications to measure flow in dirty media. Main applications are intakes and discharge areas of wastewater treatment plants, return-sludge conducts, recirculation pipelines and drainage pipelines. Further possible applications are sewer networks, measurement points for billing purposes in the wastewater sector and special wastewater constructions such as overflow structures, pump stations and stormwater overflow basins.

Challenges Of Wastewater Flow Metering

Wastewater and dirty media pose some particular challenges for sensors. Many measuring methods do not provide accurate results once the flow profile is not symmetrical. Very often the flow velocities within canals fluctuate and decrease as they approach the canal walls. In such cases, the average flow velocity must be determined by measuring at several spots and in different filling levels.

Sensors used within the medium must feature a certain robustness since wastewater very often carries along debris and other solids. NIVUS provide comprehensive expert knowledge required to place sensors on the appropriate spots and to choose suitable measurement positions.

Formation of tressing in wastewater is a frequent occurrence. Tressing is caused by building up solids carried along with the water such as fibres or hair on overhangs or edges. Due to the construction and thanks to available accessories the sensor systems can be installed so as to avoid the formation of tressing.
