This study presents a novel method for determining the liquid level from the outside of a sealed container, which is based on the balance of echo energy received by two receiving sensors. The proposed method uses one transmitting transducer and two receiving sensors that are encapsulated in a coupling plane and arranged by certain rules. The calculation and comparison of echo energy are grounded on the difference ultrasonic impedance between gas and liquid media. First, by analyzing the propagation and attenuation characteristics of ultrasonic waves in a solid, an acoustic model for calculating the echo energy is established and simulated in MATLAB. Second, the proposed method is evaluated through a series of experiments. The difference and ratio of echo energy received by two receiving sensors are calculated and compared under two different coupling conditions. Two kinds of the sensors that are arranged by different rules are selected for measuring the liquid level, and the measurement are analyzed and discussed in detail. Finally, the experimental results indicate that the proposed method can meet the proposed accuracy requirements and can effectively solve the problems caused by some poor coupling conditions.

“…In the detected circular tube material, the acoustic field from a single rectangular element can also be calculated by superposition of two-dimensional Gaussian beams. Thus, the expression of the acoustic field from the nth single element in the solid medium can be written as [26]:−iwunαfalse(x2,y2,z2false)v0=T12α:ptrue∑m=115true∑n=115dαAn1+iBmD/R1Am1+iBnD/R2×expfalse(ik1D+ik2αz2false)detG2αboldnormal(0)detG2αboldnormal(z2boldnormal)expfalse(ik1xT…”

As ultrasonic wave field radiated by an ultrasonic transducer influences the results of ultrasonic nondestructive testing, simulation and emulation are widely used in nondestructive testing. In this paper, a simulation study is proposed to detect defects in a circular tube material. Firstly, the ultrasonic propagation behavior was analyzed, and a formulation of the Multi-Gaussian beam model (MGB) based on a superposition of Gaussian beams is described. The expression of the acoustic field from a linear phased-array ultrasonic transducer in the condition of a convex interface on the circular tube material is proposed. Secondly, in order to make the tapered probe wedge better fit the curved circular tube material and carry out the ultrasonic inspection of the curved surface, it was necessary to pare the angle probe wedge. Finally, acoustic field simulations in a circular tube were carried out and analyzed. The simulation results indicated that the method of ultrasonic phased-array inspection is feasible in circular tube testing. Tube materials with different curvatures need different array element lengths and widths to get the desired focused beam.

“…The multi-Gaussian beam model first proposed by Wen and Breazeale [3] was derived from the single-Gaussian beam. The model was generalized and improved by many researchers [4][5][6][7]. Zhao [8] presented a multi-Gaussian beam model and a scattering model for dual crystal probes.…”

A nondestructive testing method for curved surfaces based on the multi-Gaussian beam model is proposed in this study. The multi-Gaussian beam model for composites coupled with water is introduced into an automatic ultrasonic testing system. A mathematical model of the received beam field is established to analyze the effect of different testing parameters on the receiving transducer. The normal vector can be calculated by variational methods to achieve the transmitting transducer's position and orientation. The position and orientation of the receiving transducer can be achieved by coordinate transformation method. The simulation and experiments illustrate the validity and effectiveness of the proposed method. Experimental results indicate that the received signal is strong and measurement accuracy is high with the proposed method. The proposed method provides an effective solution to curved composite surface parts and would significantly benefit industrial development.
