Actionable Sewer Flow Data With Less Contact Sewer Network Radar Flow Meter is designed for partially filled gravity sewers, interceptor channels and accessible manhole structures. Wastewater, grease, rags, corrosive gases and confined access make submerged velocity sensors maintenance intensive and can interrupt long monitoring campaigns. Stable flow trends help utilities identify infiltration and inflow, compare dry- and wet-weather response, verify capacity and investigate overflow risk. Built Around Fouling, Corrosion and Access Constraints The non-contact radar system measures surface velocity and water level, then combines those readings with the configured channel geometry to calculate instantaneous discharge and totalized flow. Keeping the sensor above the water avoids direct exposure to silt, debris, corrosive wastewater and fast-moving flow. This approach is well suited to locations where submerged sensors would foul, drift or become difficult to reach. Continuous level and velocity data also gives operators a clearer picture than a single level reading when flow conditions change quickly. An overhead radar arrangement keeps the sensing face outside the sewage and can combine level and surface velocity for a fuller picture of changing hydraulic conditions. This page can naturally support buyer terms such as non-contact flow measurement, surface velocity sensor, water level monitoring, open channel discharge and remote flow telemetry. Support I and I Studies and Overflow Management Confirm that the manhole or chamber provides a clear radar view, a representative straight reach and safe mounting clearance; verify the hazardous-area classification before specifying electronics. Request local logging, battery or mains strategy, surge protection and a secure protocol for SCADA or temporary flow-survey data retrieval. A representative, hydraulically stable measurement section and a verified velocity coefficient are essential; irregular sections, backwater, turbulence and changing sediment profiles must be considered during commissioning.

Confirm lead time, private-label scope, drawings and country-specific approvals for the selected configuration before issuing the purchase order.
