FLOW MEASUREMENT THROUGH GIBSON METHOD
ABSTRACT. THE MEASUREMENT OF FLUID FLOW IN FORCED CONDUITS IS A GREAT CHALLENGE FOR ENGINEERS WORKING WITH HYDROELECTRIC PLANTS AND PUMPING UNITS. THE EXISTING METHODS ARE EXPENSIVE AND DO NOT PROVIDE GREAT ACCURACY. THE FLOW RATE CALCULATED USING GIBSON METHOD CAN BE VERY ACCURATE AND RELATIVELY INEXPENSIVE. THIS WORK PRESENTS SOME THEORETICAL CONSIDERATIONS AND LABORATORY RESULTS ALLOWING OBSERVATIONS ABOUT THE FEASIBILITY AND LIMITATIONS OF THE METHOD. THE ERRORS DUE TO NOISE IN THE DATA ACQUISITION SYSTEM AND FILTERING OF THE DATA ARE ANALYZED.
KEY WORDS: TRANSIENT, GIBSON, TRANSDUCER, FLOW RATE
