How the NivuFlow 750 measures Flow cannot be measured directly. Multiple factors are required to detect the flow Q: average flow velocity and the flow cross section which leads to the general formula: Q = v(average) • A The flow measurement principle as video under: www.nivus.com The flow cross section A is investigated by continuously measuring the filling level considering the channel shape. The flow velocity is detected by using the particles‘ velocity. Most media contain a certain load of dirt particles or gas bubbles which move in the same velocity as the liquid itself

Flow velocity measurement (v) using cross correlation Accurate flow measurements require precise and reliable level detection under all hydraulic conditions. The development of a level measurement system with multiple redundancy is a result of our many years of experience. Combining hydrostatic measurement, water-ultrasound and airultrasound provides solutions for all measurement tasks. The measurement method used for flow velocity determination is based on the principle of ultrasonic reflection. One of the most modern and most efficient measurement methods for flow velocity detection is the...
