The ZGL product, a professional measurement device for interface liquid level in oil field and petrochemical industry storage tanks such as sedimentation tanks, separation tanks, sewage tanks, and storage tanks, has been successfully developed by discarding traditional technologies like capacitive, radio frequency admittance, and float ball level measurement methods. It utilizes advanced matrix high-precision sensing structures, coupled with a unique lateral quantitative magnetic field scanning and directional weak magnetic field receiving technology with error correction codes. This innovative approach addresses the drawbacks of capacitive and radio frequency admittance technologies, which are sensitive to material adherence, temperature, and humidity, and prone to drift and instability. It also solves the issues of float ball systems, which are susceptible to sticking in thick materials and clogging. The special probe protection material and advanced measurement technology make the ZGL product durable against corrosion, resistant to high temperatures, and not affected by steam or material adherence. It boasts a long lifespan with no moving mechanical parts, and its straightforward design ensures easy operation (simply power on the device to output the correct interface position after connecting the wires correctly in the field). This eliminates the need for the繁琐 process of repeatedly draining and filling liquids, which is generally not permitted in industrial settings.
Hundreds of ZGL products have been in use at oil fields for 10 to 15 years, including high-temperature and high-humidity areas in southern China as well as the extreme temperature variations in the northwestern and northeastern regions of China during harsh winters and scorching summers. Their continuous and reliable operation over the long term has fully demonstrated the superiority and practicality of the ZGL series. The ZGL series interface measurement products represent a revolutionary innovation in oil-water interface measurement for the oil field and petrochemical industries. Technology that prioritizes people will greatly facilitate the control of the oil production process in oil fields.Say goodbye to the daily chore of manually "fishing out" measurements from large drumsIn the era, oilfield workers no longer have to climb the large tanks in shifts, risking their lives in harsh weather conditions.Measure tapeDocumenting the status of the liquid-gas interface within the tank can be clearly done within the control room, enabling more targeted control of valve opening for liquid discharge and intake, no longer relying on repeated trial and error based on experience. Its use not only reduces the labor intensity for workers and conserves energy but also significantly enhances the storage tank's operational efficiency and production effectiveness.
