Particularly, hydraulic researches depend directly on the knowledge of certain important and variable parameters. A hydraulic system (airlift pump) that requires a continuous measurement of air pressure and water level has been proposed to us as a problem. Previously, traditional solutions have been proposed using mechanical measurement methods such as the U tube manometer for pressure and an ordinary ruler to measure level. These methods, as well as having slow time constants which means slow response, introduce also a wide error margin. Likewise, the measures analysis needs mathematical calculation and graphics plotting. This removes the possibility of the measurements’ real-time visualization and analysis. In this document, we propose an electronic solution consisting of a group of sensors measuring pressure and water level in real time with higher precision and a smaller error margin. These sensors surround a microcontroller whose function is the processing of the data coming from the different sensors and the controlling of the whole process. Additionally, the data is sent from the microcontroller to computer through USB cable in order to visualize clearly, register and plot the values. The management of data in the computer is done by an application with a graphic interface that represents the software part added to the hardware part to form the whole system.

Fluid flow measurement based on ultrasound / Abdelhak Boudehane 

Public ISBD Titre : Fluid flow measurement based on ultrasound Type de document : texte imprimé Auteurs : Abdelhak Boudehane, Auteur ; Mourad Adnane, Directeur de thèse ; Rabie Messahli, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2016 Importance : 32 f. Présentation : ill. Format : 30 cm. Accompagnement : 1 CD-ROM. Note générale : Mémoire de Master : Electronique : Alger, Ecole Nationale Polytechnique : 2016 Bibliogr. f. 33 Langues : Anglais (eng) Mots-clés : Measurement Flow Difference  of  pressure Sensors Index. décimale : Ms13116 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.
