YIGEQI Dual-Flange Level Gauge for Sulfuric Acid Storage Tank Measurement

2026-02-20

Precise Tracking of the Injection Process

When sulfuric acid is continuously injected into the storage tank through pipelines, the liquid level rises rapidly. The sulfuric acid flows at high speed, impacting the tank wall and causing changes in the internal pressure. Traditional level gauges struggle to accurately capture these changes under such dynamic and complex conditions.

YIGEQI's dual-flange level gauge, with its sensitive differential pressure sensing system, can capture the rapid rise in liquid level during sulfuric acid injection in real time. Under conditions of high-speed sulfuric acid impact on the tank wall and pressure fluctuations, its specially designed flange can accurately sense pressure changes and quickly convert the signal into precise liquid level data.

Furthermore, the dual-flange design enables the level gauge to accurately measure liquid level changes with minimal error and rapid response. Precise level data allows for more efficient addition and discharge of sulfuric acid, optimizing the process and improving production efficiency.

Stability Monitoring During Storage

Sulfuric acid is not completely static when stored in tanks:

● Affected by ambient temperature fluctuations, the sulfuric acid inside the tank undergoes thermal expansion and contraction.

● The heat generated by the chemical reaction also causes weak convection within the liquid.

● The pressure in the gas phase space inside the tank is unstable due to factors such as air temperature and material evaporation.

These factors combine to cause ordinary level gauges to drift when facing such a complex environment over a long period, failing to provide reliable level information. This poses a significant challenge to the stability and accuracy of Yigeqi's level measurement.

YIGEQI's measuring instruments use highly corrosion-resistant materials such as Hastelloy for their wetted surfaces, effectively resisting sulfuric acid corrosion and ensuring long-term stable operation.

Meanwhile, their advanced signal processing algorithms effectively filter out interference signals caused by gas pressure fluctuations and liquid convection, providing stable and reliable liquid level data

Sulfuric Acid Output and Usage

When sulfuric acid is extracted from the production line, the liquid level gradually decreases. Accurately monitoring the remaining liquid level ensures that production will not be interrupted due to insufficient sulfuric acid supply. As the liquid level decreases, the flow pattern within the tank changes. Sulfuric acid near the bottom is affected by both gravity and the extraction force from the pipeline, resulting in complex changes in flow velocity and pressure. Traditional level gauges often exhibit significantly increased errors when measuring low liquid levels.

Reliability Guarantee in the Output Process

The German signal processing module effectively combines static pressure and temperature compensation, ensuring good measurement accuracy and stability under a wide range of static pressure and temperature variations. This advantage means that the measurement accuracy of the Eger dual-flange level gauge remains unaffected when the liquid level decreases due to sulfuric acid extraction.

At any stage, YIGEQI's dual-flange level gauges provide a high-precision measurement of ±0.1%, fully meeting production requirements.
