  • Precise Flow Monitoring - Water flow sensor tracks liquid consumption from 0.2 to 8L/min with ±5% pulse accuracy, delivering consistent data for automated water dispensing systems. Hall effect technology ensures uniform readings across 3.5-24V applications.
  • Industrial-Grade Durability - POM construction and embedded impeller withstand 1.75MPa pressure while countering degradation. Water-Tight Hall module maintains stability in environments up to 80°C, outperforming standard plastic sensors.
  • Universal Compatibility - G1/4in PE pipe interface connects seamlessly to water dispensers, heaters, and irrigation systems. Compact design installs in tight spaces while 3-wire cable (red/black/yellow) simplifies electrical integration.
  • Low-Maintenance Function - Hall sensor generates clear pulse outputs without mechanical contacts, eliminating aging. Pre-installation screen blocks clogging from debris, reducing service interruptions and extending component lifespan.
  • Fail-Safe Performance - Water-Tight flowmeter maintains output integrity during voltage fluctuations (DC3.5-24V). Pulse output stays within 4.6V-0.5V range at 5V input, ensuring compatibility with most control boards and microcontrollers.

  • The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.
  • The principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.
  • The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.
  • High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm; liquid, powder, and particulate matter can be detected.
  • The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage (high level) of the signal terminal (green line); when the DIP switch is dialed up, the high level is 5V; when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards.
