Powerful Tools Representing Depth and Velocity Sewer Flow Data
The scattergraph is a powerful tool that displays depth and velocity data from a sewer flow monitor. The resulting patterns form characteristic signatures that provide insight into the conditions within a sewer. The flow monitor data also leave distinct patterns that even allow the performance of the flow monitor itself to be evaluated.
