The intelligent non-contact level detector (hereinafter referred to as the level detector) utilizes advanced signal processing technology and a high-speed signal processing chip, overcoming the limitations of wall thickness and achieving true non-contact measurement for liquid levels within a sealed environment. The level sensor (probe) can be installed at the top and bottom of the measuring wall (representing high and low levels). It is suitable for non-metal installations without the need to drill holes, allowing for easy installation and improved production efficiency. This device can measure various toxic substances, strong acids, alkalis, and other liquids in high-pressure sealed tanks. Its applications are extensive, with no specific requirements for liquid media or container materials. 1: The model suitable for non-metal pipes does not require contact with the liquid and is resistant to corrosion from strong acids and other aggressive liquids. It is unaffected by scaling or other impurities. 2: The intelligent level adjustment and memory function allows for multiple point connections and displays the current level status, enabling non-contact detection of liquid levels in closed containers. The sensor is installed on the upper and lower sides of the container (indicating high and low levels). It does not require hole drilling for non-metal containers and can effectively measure various fluids, strong acids, and alkalis in high-pressure airtight conditions. DIY Supplies: Electrical The liquid level sensor has no restrictions on liquid type and container materials, making it widely applicable. Installation is straightforward and does not disrupt production processes.
