In the field of chemical production, sulfuric acid, as a highly corrosive and widely used basic raw material, is of great significance in the aspects of storage and monitoring. The accurate measurement of the liquid level in sulfuric acid storage tanks has always been the focus of attention in the industry. Yigeqi's measuring instrument - the double - flange level gauge - provides an efficient and reliable solution to this problem and has demonstrated excellent results in practical applications.

When sulfuric acid is continuously injected into the storage tank through the pipeline, the liquid level rises rapidly. The high - speed flow of sulfuric acid impacts the tank wall, and the pressure inside the tank also changes accordingly. It is very difficult for traditional level gauges to accurately capture the liquid - level changes under such dynamic and complex working conditions.

Thanks to its sensitive differential - pressure sensing system, Yigeqi's double - flange level gauge can capture the rapid rise of the liquid level in real - time when sulfuric acid is being injected. Even when sulfuric acid impacts the tank wall at high speed and the pressure fluctuates, its specially designed flanges can accurately sense the pressure changes and quickly convert the signals into precise liquid - level data.Moreover, the double - flange design enables the level gauge to accurately measure liquid - level changes with small errors and fast response speed. The accurate liquid - level data makes the addition and discharge of sulfuric acid more reasonable, optimizes the process, and improves production efficiency.

When sulfuric acid is stored in the storage tank, it is not in a completely static state.

· Affected by the fluctuations of the environmental temperature, the sulfuric acid in the tank will expand with heat and contract with cold.

· The heat generated by the chemical reaction will also cause a slight convection within the liquid.

· The pressure in the gas phase space of the storage tank is unstable due to factors such as the air temperature and the volatilization of the materials.

These factors are intertwined. When ordinary level gauges are faced with such a complex environment for a long time, the measurement data is prone to drift, and they are unable to provide reliable liquid - level information. This also poses a severe challenge to the stability and accuracy of Yigeqi's liquid - level measurement.

The wetted materials of Yigeqi's measuring instruments are made of highly corrosion - resistant materials such as Hastelloy, which can effectively resist the corrosion of sulfuric acid and ensure long - term stable operation. At the same time, its advanced signal - processing algorithms can effectively filter out interference signals generated by gas - phase pressure fluctuations, liquid convection, etc., and provide stable and reliable liquid - level data.

When sulfuric acid is drawn from the production line, the liquid level gradually drops. At this time, accurately grasping the remaining liquid level can ensure that the production process will not be interrupted due to insufficient sulfuric acid supply. As the liquid level decreases, the flow state of the liquid in the tank changes. The sulfuric acid near the bottom is affected by the combined action of gravity and the extraction force of the pipeline, resulting in complex changes in flow rate and pressure. When traditional level gauges measure low liquid levels, the errors often increase significantly.

The German signal processing module can effectively combine static pressure and temperature compensation, ensuring good measurement accuracy and stability under a wide range of static pressure and temperature changes. This advantage enables the Yigeqi double-flange level gauge to maintain its measurement accuracy unaffected when the liquid level drops due to the extraction of sulfuric acid.

At any stage, the Yigeqi double-flange level gauge can achieve high-precision measurement with an accuracy of ±0.1%, which fully meets the production requirements.
