  • The intelligent non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid.
  • High and low level output: If there is induction, the output is high level; no induction, the output is low level. Specially designed for non-metallic pipe liquid level detection
  • The liquid to be tested is required to be electrically conductive, the contact surface is non-metal, and the pipe is easy to install and can be widely used.
  • The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected.
  • The intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container.
