Ультразвуковий амплітудно-частотний витратомір. Ч.1 Ультразвуковий вимірювальний перетворювач

Abstract

In the master's qualification work was designed the ultrasonic measuring transducer of ultrasonic amplitude-frequency flowmeter. Was review of the literature on which defines the purpose, tasks, project work. Was analyze existing gas flowmeter, developed structural and schematic diagram of ultrasonic measuring transducer of ultrasonic amplitude-frequency flowmeter, performed circuit simulation, developed printed circuit board of device. Based on a systematic approach to the calculation scheme developed ultrasonic measuring transducer of ultrasonic amplitude-frequency flowmeter which provides the measuring the volumetric flow of gas in a wide range of diameters of pipes with greater accuracy.
