Pipeline level sensor is a sensor that uses the capacitance principle to detect water pipe level. The main principle is to judge the change of liquid level based on the different capacitance in different media. It detects whether there is water in the sensor position, and does not need to carry out mechanical movement, and has the characteristics of long life, convenient installation and micro-power consumption. Compared with the traditional mechanical sensor, the pipeline level sensor solves the problem of low precision and stuck failure; the pipeline level sensor is widely used in sweeping robot, ground washer, mop, water dispenser, humidifier, coffee machine, dishwasher, and provides stable and reliable liquid level monitoring function for these equipment. By adopting the capacitance principle, the sensor effectively avoids the defects of the traditional mechanical sensor, and provides an important guarantee for the automatic control and maintenance of the clean water pipe system. Therefore, the principle and application of pipeline photoelectric liquid level sensor have brought great progress in the monitoring technology of clean water pipeline system, providing users with more convenient and reliable use experience.
