What is non-contact radar flow monitoring and why is it ideal for sewer applications?

Non-contact radar measures flow from above — zero contact with sewage. 5 advantages: maintenance-free, all-weather, no-shutdown install, wide range, battery-powered

Non-contact radar flow monitoring uses radar sensors mounted above the flow to measure surface velocity and water level, calculating flow rate without contacting the wastewater. Sensors install at manhole tops or above pipes.

Five key reasons it excels in sewers: 1) Non-contact — no contact with corrosive sewage, no clogging, zero maintenance; 2) All-weather — unaffected by fog, foam, or floating debris with multi-band radar; 3) No-flow interruption installation — deploy without shutdown; 4) Wide range — measures trickle flow to full pipe; 5) Battery + solar powered — operates years without grid power.

CSSOC HZ-KSLF multi-band Doppler radar flow meters have proven long-term reliability (MTBF >5 years) in urban drainage projects across Zhejiang Province.
