Non-Contact Water/Liquid Level Sensor for 3-10 mm Diameter Pipelines

CQRobot non-contact liquid level sensor realizes non-contact detection of liquid level in closed containers. It uses advanced signal processing technology and high-speed signal processing chip to break through the influence of container wall thickness. It is easy to install and use, and can detect the liquid level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure closed containers. The sensor is equipped with 2 DIP switches and is compatible with Arduino, Raspberry Pi and other motherboards.
