ZThe GL product, a professional measuring device for interface liquid level in oil fields and petrochemical industry, such as oil settling tanks, separation tanks, sewage tanks, and storage tanks, eschews traditional technologies based on capacitive, radio frequency admittance, float ball, etc. It has been successfully developed with an advanced matrix high-precision sensing structure, combined with a unique lateral quantitative magnetic field scanning and directional weak magnetic field receiving technology with grading error correction codes. It fundamentally resolves the drawbacks of capacitive and radio frequency admittance technologies, which are prone to material attachment, sensitive to temperature and humidity, and have large drift and instability, as well as the issues of float ball technology, which is prone to clogging in thick materials. The special probe protection material and advanced measurement technology make the ZGL product corrosion-resistant, heat-resistant, not afraid of steam, not sticking to materials, with no mechanical moving parts for long life, and a user-friendly design for easy installation and operation.（Field measurement interface, proper wiring and power on to output the correct interface position.）Eliminates the need for repeated fluid draining and refilling during the on-site adjustment of capacitive and admittance products (usually not allowed in industrial sites), and a series of cumbersome processes.

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 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 solution for oil-water interface measurement in the oil field and petrochemical industries. Technology with a human touch, their successful application will greatly facilitate the control of the oil production process in oil fields.Say goodbye to the daily labor of manually "fishing out" the ruler from large drums.In the era, oil field workers no longer have to risk their lives in harsh weather conditions, climbing large tanks in mandatory, life-threatening shifts around the clock.Measure stickRecord taking is made easy, allowing the control room to clearly understand the interface condition inside the tank, thereby enabling more targeted control of valve opening for liquid discharge and intake, rather than relying on repeated trial and error based on experience. Its use not only reduces the labor intensity for workers and saves energy but also significantly improves the storage tank's efficiency and production effectiveness.
