Measuring with NivuFlow Stick The flow velocity is measured by the ultrasonic cross correlation measurement principle. Thanks to this technology, the sensor can measure velocities at different water depths with high resolution. This brings a great advantage in terms of measuring time as well as a more accurate determination of the flow velocity curve. Our cross correlation sensors are equipped with a pressure measurement cell for reliable level measurement. Measuring Principle: Cross Correlation Method (Tracking Method) t h(p) v Scatterers (particles, minerals or gas inclusions) present in the medium...
