The ZGL product, a new generation of professional measurement equipment for interface level in oil fields and petrochemical industry oil sedimentation tanks, separators, wastewater tanks, and storage tanks, eschews traditional methods such as capacitive, radio frequency admittance, and float ball technologies for interface and level measurement. It is developed using advanced matrix high-precision sensor structures, combined with a unique lateral quantitative magnetic field scanning and directional weak magnetic field receiving technology with a grading error correction code function. This product fundamentally solves the drawbacks of capacitive and radio frequency admittance methods, which are prone to material attachment, heavily affected by temperature and humidity, with large drift and instability, as well as the issues of float ball methods that are prone to stickiness and clogging. Special probe protection materials and advanced measurement technology enable the ZGL product to have long-term corrosion resistance, high-temperature resistance, steam resistance, non-adhesive material resistance, no mechanical moving parts for long life, and a傻瓜式 (simple and easy) design that makes tuning and use straightforward (on-site interface measurement, correct wiring, and the machine outputs the correct interface position upon startup). This eliminates the need for the繁琐 process of repeatedly draining and refilling fluids (typically not allowed in industrial sites) for capacitive and admittance methods during on-site tuning.
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 and the extreme temperature variations in the northwestern and northeastern regions of China during severe 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 breakthrough in oil-water interface measurement for the oil field and petrochemical industries. Technology that puts people first, their successful application will greatly facilitate the control of the oil production process in oil fields.Say goodbye to daily manual "dredging" with large drums.In the era, oilfield workers no longer have to risk their lives in hazardous weather conditions, climbing the large tanks in mandatory shifts day and night.Reach measureDocumenting the situation, the control room can clearly understand the interface condition inside the tank, thereby conducting valve control and fluid release/injection more purposefully; no longer relying on repeated experience. Its use not only reduces the labor intensity of workers and saves energy but also significantly enhances the storage tank's operational efficiency and production effectiveness.
