The ultrasonic Lamb wave detection principle can realize the noncontact measurement of liquid level in closed containers. When designing an ultrasonic Lamb wave sensor, it is vital to thoroughly study and select the optimal wedge size at the front of the sensor. In this paper, firstly, we select the best working mode of Lamb waves according to their propagation dispersion curve in aluminum alloy, and we obtain the best angle of wedge through experiments. Secondly, we study the impact of the size of the wedge block on the results, and we obtain the selection method of wedge block parameters. The evaluations show that, when the frequency–thickness product is 3 MHz·mm, the Lamb waves work in the A1 mode, and the experimental effect is the best. At this time, the incident angle of the ultrasonic wave is 27.39°. The wedge thickness should be designed to avoid the near-field area of the ultrasonic field, and we should choose the length as odd multiples of 1/4 wavelength. The rules obtained from the experiment can effectively select the best working mode for ultrasonic Lamb waves, while also providing a basis for the design of the wedge block size in a Lamb wave sensor.

Liquefied petroleum gas (LPG) is widely used in cooking food by most Brazilian families, and is popularly known as "cooking gas". It has as characteristic to be one of the lightest fractions of oil and its burning is very clean, with very low emission of pollutants. Due to these characteristics, it is used indoors, such as in the kitchen, or in industrial applications sensitive to pollutants, such as in the manufacture of glass, ceramics and food (PETROBRÁS, 2021).

“…Substituting c and f0 in Table 2 into Equation ( 4) can obtain the wavelength of ultrasonic waves propagating in PMMA, which is λ = -3 × 2.775 10 m. Substituting λ, D1, and D2 into Equation (3) gives N1 = 0.9 cm and N2 = 2.03 cm. Therefore, in order to explore the relationship between the length of the near-field area and the ultrasonic echo energy, we customized some PMMA rods with different lengths and conducted experiments in groups.…”

In the method of monitoring the liquid level based on ultrasonic impedance, the near-field effect can seriously affect the validity of the results. In this paper, we explore the factors affecting the length of the ultrasonic near field. Based on that, we propose the optimal length and the minimum length of the buffer block to avoid the near field. The evaluations show that when the parameters of the ultrasonic probe are 15 mm in diameter, 1 MHz in frequency, and ±15 V in emitted ultrasonic wave amplitude, the best results are obtained when the length of the buffer block is 22 mm. When the probe diameter is 10 mm, the buffer block length should be ≥5 mm to ensure the validity of the measured results. The evaluation precision is 1 mm. This research can effectively avoid the blind area of emitted waves when using ultrasonic to measure the liquid level. It provides an effective basis for the selection and design of ultrasonic probes.
