Abstract

The mass flow measurement is generally necessary in light fuel oil delivery, but measurement value of the ultrasonic flow meter is volume flow rate, it cannot meet the requirement of mass flow measurement. In this paper, relationship between the light fuel ultrasonic velocity, fuel density and temperature is analyzed through a large number of experimental data, the neural network model of different light fuel density and temperature and its ultrasonic propagation velocity is found. By use of this network model, a method of mass flow measurement by a ultrasonic flow meter has been given. Compared with the density compensation method,this method do not need to enter the fuel standard density, and can further improve the light liquid fuel mass measurement accuracy,density error is less than 0.23%, error of mass flow is less than 0.35%.
