Background. The aim of the article is to analyze the possible solutions for level measurement of liquids and demand urgent ways for the innovative design of the level of liquids sensors used in a variety of measurement tasks.
Materials and methods. Was analyzed the analogy between the propagation of waves in an acoustic environment, and the transmission line that allows you to describe the electromechanical transmission signal in the piezoelectric material, which is the basis of the ultrasonic transducer operating element. preliminary ultrasound
systems modeling problem reduces to the construction of the ultrasonic transducer using a model of electrical components, such as a transmission line and controlled sources of current and voltage.
Results. A method for computer modeling of the output signal from the ultrasonic transducer at the initial stage of the engineering design of the finished electronic product.
Conclusions. We offer advice on the design of liquid level sensors substances taking into account possibilities of computer simulation to ensure reliable operation in real conditions for solving measurement tasks of varying complexity.
