Level & Flow Solution

The Level & Flow Solution is built around the VEGA C21 non-contact radar sensor for accurate level measurement in sewer and stormwater systems. The compact design makes it easy to install even in confined spaces, and the narrow beam angle ensures reliable readings in complex geometries.

For applications requiring precise flow measurements — such as billing, hydraulic modelling, or regulatory reporting — the system can be equipped with an optional Pulsar MicroFlow surface velocity sensor. Combining level and velocity enables accurate real-time flow calculations even in challenging conditions.

All data is logged and transmitted automatically to the cloud, allowing operators to monitor system behaviour and receive alarms on abnormal conditions.
