Overview
Overview
The Ott C31 is a robust mechanical current meter designed for precise flow velocity and discharge measurements in rivers and open waterways.
Its versatile design allows the C31 to be used with a hand-held wading rod for measurements in smaller streams and shallow water, or cable-suspended from a bridge, boat, or cableway for measurements in deeper water and at higher flow velocities.
With a measurement range of 0.025 to 10 m/s, the C31 provides a flexible solution for applications ranging from small streams to large rivers. A variety of accessories, including sounding weights, sounding reels and cableway equipment, enables complete flow-measurement setups for different site conditions.
