The working principle of the ultrasonic level gauge

1. Introduction of externally attached liquid level gauge: It adopts the leading digital signal processing technology to avoid the influence of the wall thickness of the container, and realizes the real non-contact measurement of the liquid level in the closed container outside the tank. The sonar sensor (probe) is installed just below the outer wall (bottom) of the container to be tested. It does not need to open holes in the container to be tested. It is easy to install and can be installed and debugged online without affecting production. It can accurately measure the liquid level of various flammable, explosive, toxic and other dangerous media, strong acids, strong alkalis and various pure liquids in high temperature and high pressure airtight containers. 2. The working principle of the externally attached liquid level gauge: H=v×(t/2-tg/2)×αH: liquid level height v: speed of sonar wave propagation in liquid t: sonar wave used from launch to return Time tg: the transmission time of the sonar wave in the tank wall α: correction coefficient The externally attached liquid level meter adopts the principle of sonar ranging, uses a special probe attached to the outside of the container wall to collect sonar signals, and uses special sonar wave processing technology as the system The core adopts advanced high-speed signal processing technology, and uses the special algorithm of Shaanxi Kaidi to accurately calculate the liquid level in the container. The calculated liquid level value is displayed locally and the remote signal is output. The instrument can output the measurement results to the control center through (4～20)mA analog signal, Hart, RS-485, Ethernet and other interfaces, and can also use Wi-Fi, Bluetooth, Hart, RS-485, infrared, Ethernet and other interfaces Debug online. As shown in the figure, when measuring the liquid level, the sonar wave signal is emitted from the probe, and the echo signal is detected by the probe after being reflected back by the liquid surface. The echo signal is processed by a proprietary algorithm to calculate the time t, and the system calculates the liquid level according to the formula
