Abstract [en]

This licentiate thesis addresses the idea of measurement of the density of liquids using sound. The thesis can be dived into three sections: 1. An introduction that presents the need for the research and its future application into an ultrasonic mass flow meter. 2. Experimental results of an ultrasonic density probe (paper 1 and 2) which evaluate the probe's concept with liquids ranging from 750 to 1300 kg/m over temperatures extending form 0 to 40°C. Thermodynamic measurements are also presented. 3. Comparisons of experimental versus theoretically based simulation of ultrasonic systems (paper 3). The theory allows the simulation tool to predict sound generation, propagation and reception as a function of frequency and temperature. Within the thesis are three papers: 1. An Ultrasonic Density Probe. (published in IEEE Ultrasonic symposium) 2. Thermostatic and dynamic performance of a Density Probe. (submitted to IEEE Transactions on UFFC) 3. PSpice simulation of Ultrasonic Systems. (submitted to IEEE Transactions on UFFC)
