NIVUS - Model II -Pipe Profiler

The measurement system ensures highly accurate determination of flow rates even under difficult conditions such as low flow volumes or poor hydraulic flow conditions.

• Verification of channel utilisation
• Calibration basis for hydraulic calculation models
• Determination of required renovation extents
• Determination of required reservoir volumes (retention basin)
• Introduction of a channel management system
• Localisation of extraneous water volumes
• Influent control
• Throttle discharge control
• Determination of basic data for new billing networks
