Liquefied petroleum gas (LPG), whose main components are propane and a small amount of butane liquefied gas, is stored in a storage tank container in a liquid state under appropriate pressure and temperature. In the refining process of the petrochemical industry, the liquid level measurement of the liquefied balloon tank is often encountered, but because the liquefaction degree of the liquefied gas is greatly affected by the temperature and pressure changes, the traditional liquid level measuring instrument often cannot accurately measure the liquid level. The externally mounted liquid
level gauge is a non-contact liquid level gauge with ultrasonic measurement technology. No need to open holes, the ultrasonic probe can be measured by sticking to the bottom of the storage tank. There is no limit to the pressure in the container. It can measure flammable, explosive and strong corrosive media. It is easy to install and does not need to stop production. It is a safe, convenient and stable choice for liquid level measurement of liquefied petroleum gas (LPG) storage tanks. 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 height according to the formula. H : The height of the measured liquid level t : The time it takes for the sonar wave to return from the launch to the return tg : The transmission time of the sonar wave in the tank wall v : The speed of the sonar wave propagating in the liquid α : Correction coefficient Features of the externally mounted liquid level gauge ■Sonar wave non-contact measurement, safe and stable ■High measurement accuracy, low error temperature, liquid level can be measured ■Mature two-wire system, easy to install and easy to debug, the magnetic probe can be measured at the bottom ■Multi-protocol (RS485, HART, Modbus, etc.), can be connected to DCS, SIS system, can realize remote transmission of measurement data Real-time understanding of data changes.
level gauge has become a crucial product for marketers, especially when it comes to brand building and engaging potential customers.
