The ADV Doppler flowmeter has been deployed in the drainage networks of cities across Northwest China, supporting the monitoring and maintenance of manhole flow rates.
2026-09-14
In northwestern cities, the drainage pipe network spans vast distances, and the conditions inside manholes are highly complex. Local authorities have deployed Adv Doppler flow meters to establish an intelligent manhole‑level flow monitoring system, thereby enhancing the digital management and control capabilities of the drainage network.
Based on the Doppler measurement principle, the device can accurately collect velocity and flow‑rate data within manholes even under sediment‑laden wastewater conditions, making it well suited to the complex, damp, and debris‑filled environments found underground. Installation is straightforward: the unit is simply deployed inside the drainage manhole without requiring major modifications to the existing pipe network. With a high ingress protection rating, it resists windblown sand and sediment buildup, minimizing damage to the sensor probe caused by underground contaminants and reducing the frequency of costly, labor‑intensive in‑manhole inspections and maintenance.
Data can be wirelessly uploaded to the management platform in real time, enabling administrators to remotely monitor changes in manhole flow and proactively identify risks of pipe blockages and overflows, thereby shifting from reactive emergency repairs to proactive operations and maintenance. Meanwhile, the device features a streamlined design, with simple routine inspection and maintenance procedures, significantly reducing operational and maintenance costs for large-scale pipeline networks across Northwest China and providing reliable data support for urban drainage scheduling and pipeline health assessments.
