Development of an Acquisition System for Thermal Mass Flow Sensors

This thesis deals with the design and implementation of a control and acquisition system for Thermal Mass Flow sensor in industrial applications. A detailed analysis of the characteristics of thermomassic sensors is presented, followed by a description of the fundamental parameters to be acquired and processed for the applications of interest: three different acquisition and control systems will then be analyzed, with their respective advantages and disadvantages. Finally, the design and implementation of the chosen system is presented, in a first prototype with a discussion on the results obtained and possible future applications. The project was developed in collaboration with Sit Spa, in its laboratories in Padua.
