ZGL products abandon traditional interface and liquid level measurement technologies that rely on capacitive, radio frequency admittance, float ball, and other principles. Instead, they utilize an advanced matrix high-precision sensor structure, combined with a unique lateral quantitative magnetic field scanning and directional weak magnetic field receiving technology with error correction codes. This results in a new generation of professional measurement equipment for oilfield and petrochemical industry storage tanks, separation tanks, wastewater tanks, and storage tanks. It fundamentally solves the issues of capacitive and radio frequency admittance technologies, such as being prone to material adhesion, greatly affected by temperature and humidity, significant drift, and instability, as well as the drawbacks of float ball systems, which are prone to sticking and clogging. The special probe protection materials and advanced measurement technology ensure the ZGL products have long-term corrosion resistance, high-temperature resistance, resistance to steam, non-adhesion to materials, long lifespan without mechanical moving parts, and a user-friendly design that is simple to install and operate (on-site interface measurement, correct wiring, and power on to output the correct interface position), eliminating the need for repeated liquid discharge and injection (generally not allowed in industrial sites) and other cumbersome processes during on-site debugging of capacitive and admittance products.
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 solution for oil-water interface measurement in the oil 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 routine of climbing large drums and manually "fishing out the ruler."In the era, oil field workers no longer have to risk their lives in harsh weather conditions, climbing the large tanks in mandatory, round-the-clock shifts.Measure tapeDocumenting the situation, the control room can clearly understand the interface condition inside the tank, thus controlling the opening of valves and the release or intake of liquids more purposefully; no longer relying on repeated experience. Its use not only reduces the labor intensity of workers and saves energy but also significantly improves the storage tank's efficiency and production efficiency.
