摘要:
针对金属密闭容器内液体液位测量问题，设计1种基于超声透射特性的非接触式液位测量装置。测量装置根据被测容器内液体介质与气体介质透射系数不同的原理，通过超声接收探头回波情况判断容器内液体位置，利用软件与硬件结合，调整超声发射探头与接收探头的放大倍数，实现对不同材料、厚度容器内液位的测量。测量装置可以将所测液位、容器倾斜程度等数据通过上位机、阿里云平台等多方位显示。研究结果表明：该测量装置可测量不同材料、厚度密闭容器内承装液体的液位，所测数据较为稳定，测量误差范围不大于3 mm。
Abstract:
Aiming at the problem of liquid level measurement in the metal closed vessels,a non-contact liquid level measurement device based on the ultrasonic transmission characteristics was designed.According to the principle of different transmission coefficients of liquid medium and gas medium inside the measured vessel,the device judged the position of liquid inside the vessel by the echo of ultrasonic receiving probe.With the combination of software and hardware,the magnification of the ultrasonic transmitting and receiving probes were adjusted to measure the liquid level of vessels with different materials and thicknesses.The measured data of liquid level and vessel inclination could be displayed in many aspects on upper machine,mobile APP,and Ali cloud platform.The results showed that the device could measure the liquid level of loading liquids in the closed vessels with different materials and thicknesses,the measured data was stable,and the measuring error range was within 3 mm.
