When measuring free-surface pipe flow with instrumentation, it’s important to avoid placing sensors too close to upstream or downstream bends, as this can compromise measurement quality. To illustrate this topic, this FLOW-3D HYDRO simulation compares two pipes under identical flow conditions. The outer pipe includes a sufficient straight section, resulting in a cleaner, more stable cross-section for measurement. In contrast, the inner pipe is positioned near two 90-degree bends, producing a more turbulent and uneven surface that makes accurate measurement difficult. For complex designs requiring flow measurement, CFD modeling can help identify optimal sensor locations before equipment is installed. Learn more at flow3d.com/hydro
