AI Technical Summary

Technical Problem

Existing technologies struggle to reliably measure flow velocities in pipelines within wastewater treatment plants, especially as sludge layers accumulate, and the signals from optical methods are susceptible to interference.

Method used

The presence of bubbles is measured using conductivity. Two conductivity measurement units are arranged in the delivery pipeline. The change in conductivity as the bubbles pass through is used to calculate the flow rate in conjunction with the evaluation unit.

Benefits of technology

It enables highly reliable flow rate measurement even in the presence of a layer of contaminants, simplifies the device structure, and reduces costs.
