The intelligent float level gauge is based on the principle of force balance. It adopts a new sensing structure on the basis of the early float level gauge, integrating the sensor and the lever mechanism into one. It can directly measure the buoyancy that the float experiences in the liquid, effectively solving the influence of static pressure. This instrument has outstanding features of high temperature resistance and high pressure resistance, providing a good method for measuring the liquid level in high-temperature and high-pressure containers. Moreover, this instrument has the advantages of high accuracy, good reliability, convenient adjustment, wide measurement range, durability, and high performance-price ratio. It is suitable for continuous measurement of liquid level, interface, and density in open or pressurized containers in industrial processes, and is widely used in industries such as petroleum, chemical engineering, power, food, water conservancy, metallurgy, thermal power, cement, and wastewater treatment. This instrument complies with the two-wire 4-20mA transmission protocol and has intrinsically safe type, flameproof type, liquid crystal indication type, battery type, Hart type, and various installation forms, providing users with a very wide range of choices. In addition, the high-quality circuit and sensing system ensure excellent performance in various application environments.
