3. Taidacent Non Contact Liquid Level Sensor Contactless Water Tank Water Level Sensor for Tank Water Level Control with Low and High Level Output
3
9.1/10 our score
Features
- 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.
- The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected.
- 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.
- 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
- You can adjust sensitivity: Remove the plastic cover of the sensors and turn the very small screw, clockwise decrease sensitivity, counter clockwise to increase the sensitivity.
4. Taidacent Non Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Pipe Water Float Switch NPN Output Capacitive

8.8/10 our score
Features
- 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.
- The liquid level sensor (probe) is installed above and below the outer wall of the container to be tested (the high and low positions of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect the production.
- The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected.
- 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.
- NPN output: If there is induction, the output is low level, no induction, disconnected
