SISCO portable radar flow meter exploits radar/ultrasonic hybrid or Doppler radar to measure flow without contacting the fluid (non-contact measurement). Advantages include minimal intrusion, ability to measure open channel flow (rivers, streams), and harsh environments (wastewater discharge). For monitoring stormwater, flood control, river flow, or remote sites where maintenance is challenging, SISCO portable radar meter gives flexibility and quick deployment. The non‐contact nature means no pressure drop, no in-pipe installation, and lower risk of fouling or mechanical wear. Application scope includes environmental monitoring, civil infrastructure, hydrology, and process discharge monitoring. Additionally, remote data logging and angle correction features in SISCO's model support accurate results even in variable mounting. For any scenario where direct insertion or full pipeline access is impractical (large open channels, large pipelines, buried lines), the radar flow meter delivers measurement with minimal disruption. Considering large infrastructure such as open channels, stormwater systems, flood control reservoirs or remote pipelines, SISCO portable radar velocity meter offers advantages in mobility, minimal installation, and rugged outdoor use. The meter can be transported, mounted quickly, and used to monitor flow in large open channels or pipelines without inserting sensors. This is ideal for municipalities, environmental agencies, hydrological studies, and large‐scale industrial discharge monitoring. The application scope extends to river flow measurement, urban stormwater network performance evaluation, sewer overflow monitoring, and large pipeline audits. The advantages include non-intrusion, less maintenance (no moving parts in fluid), and flexibility to adapt to different sites. For engineers facing remote locations, difficult access or future verification campaigns, the radar flow meter becomes a flexible tool that complements fixed measurement systems.
