The OTT SLD is a measurement system for continuous measurement of water velocity and level in streams, rivers, and canals. The sensor employs the acoustic Doppler principle to reliably measure flow velocity in a variety of naturally occurring conditions, including during most flood events.

                                                    measurement in rivers and open channels. Discharge

                                                    calculation based on velocity - index - method.

                                                    Integrated vessel filter algorithm, Modbus interface and

                                                    output of total volume of flow (max. interval 1 day).

Measurement range:                 ± 10 m/sAccuracy:± 1 % of measured value ± 0.5 cm/s

Ideal for monitoring:

• Reliable performance in waters with high sediment load and flood situations

• Applicable in natural rivers, streams,  shipping-, irrigation- and service water canals

• Also suitable for small waterbodies (smallest cell size 20 cm)
