- The water tank cover with meter effectively prevents leakage while maintaining pressure balance and water level stability in the tank. - As water temperature rises, the cooling water expands. If pressure exceeds safe limits, the spring mechanism in the cover opens, allowing excess water to flow into the auxiliary kettle for safe storage. - Conversely, when the water temperature drops, the reduced volume creates a vacuum. The water tank cover automatically opens to draw water back from the auxiliary kettle, ensuring consistent water levels. - Constructed from high-quality billet aluminum, this cover boasts exceptional strength and durability, making it a reliable choice for long-term use. - Ideal for a variety of applications, including residential water heating systems, industrial cooling systems, and other scenarios where maintaining optimal water levels is critical. - Compatible with standard water tanks, the cover is designed to fit seamlessly, ensuring easy installation and effective performance in any setup.
