Ультразвуковий засіб визначення густини газового потоку

Abstract

In the master's degree work, an ultrasonic method for determining the density of the gas flow has been developed, which will increase the accuracy of the measurement due to the use of interference within the near zone of the ultrasonic wave. The review of the literature on which, defined goals, tasks, project work. Existing gas density detector. The mathematical model to determine the density of gas, depending on the frequency of ultrasonic vibrations and temperature. The structural design of the electrical circuit and the detection unit with a microprocessor to calculate the ultrasonic density detector. A circuit simulation, developed PCB detection unit to calculate for ultrasonic density processing with a microprocessor. Developed measures to protect labor and safety in emergency situations.
