Flow Disturbance Compensation (FlowDC) for ultrasonic clamp-on sensors

For successful flow measurement, maintaining accuracy is crucial, especially in pipes with limited space or inlet runs. The unique FlowDC function reduces required straight inlet runs for clamp-on systems to 2 × DN downstream of pipe disturbances like elbows and contractions. FlowDC, available in Proline Prosonic Flow W 400 and Prosonic Flow P 500, ensures noninvasive measurements without pressure loss. This whitepaper addresses the two-step approach of FlowDC technology to compensate for errors introduced by distorted flow profile.
