Résumé :	Flow measurement is done using differential pressure that is often below sensors’ precision limit. Water filled U tube manometers remain the most accurate measuring instruments for low pressure values. In the other hand, they impose many problems like readability, impossibility of real time visualisation and storage. Ultrasonic transceivers, when placed above the manometer’s legs, offer solutions for the problems mentioned above. The combination of both ultrasonic transceiver with a U tube manometer offers the advantages of electronic and mechanical measurement together. This resulting measurement instrument shows efficiency and performance when applied on Pitot tube and solves the flow rate measurement problem.
