In this thesis, the experimental characterization of a test bench designed for gas flow measurement is addressed, with particular reference to hydrogen, both in pure form and in mixture with other gases (blending), such as methane, nitrogen, and carbon dioxide. The main objective is to evaluate the behavior and performance of different commercial flow meters, using the Coriolis-effect instrument as a reference, considered the standard for mass flow measurement. The experimental analysis focuses on the response of the meters under various operating conditions, flow rates, and gas types, as well as valve opening percentages, in order to provide an overview of the accuracy and reliability of the devices in the context of the energy transition towards hydrogen.
In questo lavoro di tesi si affronta la caratterizzazione sperimentale di un banco prova progettato per la misura della portata di gas, con particolare riferimento all’idrogeno, sia in forma pura che in miscela con altri gas (blending), come metano, azoto e anidride carbonica. L’obiettivo principale è valutare il comportamento e le prestazioni di diversi flussimetri commerciali, utilizzando come riferimento lo strumento a effetto Coriolis, considerato lo standard per la misura massica. L’analisi sperimentale si concentra sulla risposta dei misuratori in funzione di diverse condizioni operative, flussi e tipologie di gas, percentuale di apertura valvola, al fine di fornire una panoramica sull’accuratezza e l’affidabilità dei dispositivi nel contesto della transizione energetica verso l’idrogeno.

Abstract
In this thesis, the experimental characterization of a test bench designed for gas flow measurement is addressed, with particular reference to hydrogen, both in pure form and in mixture with other gases (blending), such as methane, nitrogen, and carbon dioxide. The main objective is to evaluate the behavior and performance of different commercial flow meters, using the Coriolis-effect instrument as a reference, considered the standard for mass flow measurement. The experimental analysis focuses on the response of the meters under various operating conditions, flow rates, and gas types, as well as valve opening percentages, in order to provide an overview of the accuracy and reliability of the devices in the context of the energy transition towards hydrogen.| File | Dimensione | Formato | |
