Product Introduction


The Borosilicate Sight Glass Diesel Fuel Tank Reflex Level Gauge Glass is a high-precision liquid level monitoring component specially developed for diesel fuel tanks. Produced through a rigorous six-step process—including raw material mixing, melting at 1500°C–1700°C for 6–8 hours, clarification, homogenization, forming, and annealing—it ensures exceptional product quality. The main raw materials include silica sand (70%-80%), boric acid or borax (7%-13%), soda ash (4%-8%), and trace amounts of alumina. Each finished product undergoes strict inspection, including chemical analysis, thermal testing, optical inspection, and visual quality checks, guaranteeing reliable performance in diesel fuel tank applications.


Borosilicate Sight Glass Diesel Fuel Tank Reflex Level Gauge Glass


Product Features


Rigorous Production Process: The 1500°C–1700°C high-temperature melting and 6–8 hours of heat treatment ensure the glass has a uniform internal structure, enhancing its strength and thermal stability.


Precise Quality Inspection: Each product undergoes chemical analysis to verify SiO₂/B₂O₃ content, thermal testing with a thermal expansion coefficient of 3.3×10⁻⁶/K, optical inspection ensuring transparency ≥90%, and visual checks for no bubbles or defects, ensuring consistent quality.


Superior Material Properties: High borosilicate glass offers high strength, hardness, and excellent transparency, resisting diesel corrosion and thermal shock, suitable for long-term use in diesel fuel tank environments.


Scenario-Specific Solutions


Diesel fuel tanks in transportation, engineering machinery, and industrial fields require accurate liquid level monitoring to ensure continuous operation and avoid fuel shortage accidents. The Borosilicate Sight Glass Diesel Fuel Tank Reflex Level Gauge Glass provides professional solutions for these scenarios.


Diesel Generator Fuel Tanks: In industrial and commercial diesel generators, this gauge glass enables real-time monitoring of diesel levels, ensuring the generator has sufficient fuel supply, avoiding unexpected shutdowns caused by fuel shortage, and ensuring stable power supply.


Engineering Machinery Diesel Tanks: For excavators, loaders, and other engineering machinery operating in harsh outdoor environments, the product's thermal shock resistance and corrosion resistance adapt to temperature changes and harsh working conditions, ensuring accurate fuel level monitoring.


Diesel Transportation Tankers: During long-distance diesel transportation, the product's high strength and sealing performance (when matched with appropriate gaskets) prevent fuel leakage and ensure accurate level monitoring, improving transportation safety.
