Feasibility of measuring flow velocity profiles with array-based clamp-on ultrasonic flow meters

Poster (2021) - D van Willigen (author), Paul van Neer (author), J. Massaad (author), N. de Jong (author), M. Verweij (author), M. Pertijs (author)

In this work, we investigate the feasibility of extracting velocity profile information with clamp-on transit-time ultrasonic flow meters. By using time delay inversion on multiple acoustic paths generated with clamp-on array transducers we extract the velocity profile inside the ...
