As soon as it arrives in the rainy season, it is flooded, and urban waterlogging caused by heavy rain has become a common problem in China’s cities and is a major problem that plagues many cities. During the rainy season or heavy rainfall, water accumulation on urban roads can cause safety accidents. In order to strengthen regional monitoring, liquid level sensors can be used to detect water accumulation at a specific depth, respond to the situation to the regulatory authorities, and issue early warning information to the public about dangerous areas. The application of liquid level sensor can play a good role in monitoring and early warning of urban drainage system. Liquid level sensors are optically used to detect whether the water level has reached a specific height, and can be used to reflect relevant information such as liquid level height, pressure and weight. In the monitoring of water accumulation on urban roads, the liquid level sensor is installed at a set warning height, especially in some low-lying areas or culverts. When the water reaches the warning height, the refractive index at the interface changes due to contact with water (relatively when there is no contact with water), which causes the light received inside the sensor to change and detect the presence or absence of liquid. Since the level sensor can only detect the water level at a specific height and cannot change the water level, it is possible to deploy multiple sensors at different heights to detect more accurately and reflect different levels and changes in water accumulation. Level sensors are also designed to continuously measure changes in the liquid level. When the ambient water level of the liquid level sensor reaches a certain depth, the pressure of the water will be introduced into the liquid level sensor, and the depth of the liquid level will be obtained by measuring the pressure value of the water. The liquid level sensor needs to choose products with high precision, strong anti-interference and good stability. The anti-clogging and anti-fouling performance of the level sensor is also important, and if there are many impurities in the water, it is very likely to cause clogging of the impulse hole. Heavy rains are often accompanied by lightning, and the lightning protection and anti-interference capabilities of the level sensor also need to be paid attention to. The liquid level sensor can obtain data information on the level of urban waterlogging and precipitation. This is the basis for the operation of deep drainage systems, early warning of the future and scientific, sustainable management. The wide application of liquid level sensors will bring us more convenient urban life.
