Public ISBD Titre : Analysis of the performance of a hydraulic slurry flow calibration rig Type de document : texte imprimé Auteurs : S. Chehbi, Auteur ; C. N. Wormald, Directeur de thèse Editeur : Bradford : University of Bradford Année de publication : 1983 Importance : 79 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Magister : Control Engineering : Bradford, University of Bradford : 1983 Bibliogr. f. 80 Langues : Anglais (eng) Mots-clés : Hydraulic slurry flow calibration rig  Flow-rates Calibrating flowmeters Diverter system Fluctuations -- the flow-rate Index. décimale : M006183 Résumé : The projet aimed at analysing the performance of the Hydraulic Slurry Flow Calibration Ring, recently installed at the department of Control Engineering. This rig is intended for calibrating and testing liquid flowmeters in the range of small and medium flow-rates, which can be extended up to 90 litres oer second. A survey of the various methods of calibrating flowmeters with liquids, as well as the advantages and disadvantages of these methods is presented. The accuracy and operational performance of the Hydraulic Slurry Flow Rig is then considered, and for this purpose a classification of possible errors is made. Operational problems were encountered during the running of the rig, of which the first was related to the diverter system which is used to direct the flow into and out of the weightank. The second problem was the unconstancy and fluctuations of the flow-rate in the test lines, particularly during the diversion periods. These problems were investigated and possible solutions to them, including the use of a microcomputer in order to overcome them are also presented in here.

Development of a mass flowmeter for a high density/two phase flow / Kais Benotmane (1983)

Public ISBD Titre : Development of a mass flowmeter for a high density/two phase flow Type de document : texte imprimé Auteurs : Kais Benotmane, Auteur ; C. N. Wormald, Directeur de thèse Editeur : Bradford : [s.n.] Année de publication : 1983 Importance : 80 f. Présentation : ill. Format : 30 cm. Note générale : Master thesis : Electronic :University of Bradford : 1983 Bibliogr. f. 81 Langues : Anglais (eng) Mots-clés : Electrostatic transducer Débit massique Flow measurement Index. décimale : Ms00983 Résumé : The work presented in this dissertation involves the developement of a mass flow measurement device which can work reliably in typical industrial environment. The instrument might well be required to operate with different materials, particles sizes, particles shapes, inpurities and changing conveyor gases. As well as to operate under different transportation conditions of solids loadings and velocity. Moreover an instrument which is independant of the physical state of the process flow is highly desirable. A possible solution consists of two measurement. i/ Solids velocity by cross-correlation technique. ii/ Rate of flow momentum change by force (F) sensor. Finally, all our experiments were carried out on a pipe of 5.3 mm of diameter where the air density was of 1.2 Kg/m.
