[0002] An insulated water tank is a device used to store and keep hot water warm. It is usually composed of an outer shell, an inner tank, an insulation layer, and a heating device. The outer shell is the external packaging of the insulated water tank, and is generally made of metal materials such as stainless steel or galvanized steel plates, which have good corrosion resistance and strength. The inner tank is the internal container of the insulated water tank, and is generally made of food-grade stainless steel, which is corrosion-resistant and hygienic.

[0003] A water level sensor is a device used to detect the height of liquid water levels. It is commonly used for water level monitoring and control in water tanks, pools, rivers, lakes and other water bodies. The working principles of water level sensors can be divided into many types, including float type, pressure type, ultrasonic type, etc. Among them, the pressure type water level sensor indirectly detects the water level by measuring the liquid pressure. The sensor converts the pressure into an electrical signal and determines the water level by measuring the changes in the electrical signal.
