For large canals, most especially rivers, the flowmeter for this purpose is the PHOENIX non-contact RADAR area/velocity flowmeter. It operates and has same principle with Raveneye open channel flow meter, but the Phoenix offer more range in the channel width and the height of installation (usually under a bridge).
Aside from rivers, other applications are canals, large irrigation, stream monitoring, in water management, flood prevention or monitoring, hydropower plants, rain basin modeling, large wastewater channels and more.
