(Summary description)　　What happens when the water level is too high? Can industrial IoT sensors help smart cities build effective flood warning systems? 　　Fortunately, current technology makes it easier to quickly deploy environmental monitoring solutions. In this article, we will focus on how IoT devices monitor the water level of the flood warning system. 　　How does the IoT water level sensor work?   　　You have many options for how to monitor the water level, and there are many hardware manufacturers and various technologies available. Let us discuss common IoT water level sensors, you can choose from them: 　　★Ultrasonic liquid level sensor 　　★Pressure Sensor 　　★Radar level sensor   　　Ultrasonic liquid level sensor 　　Under normal circumstances, ultrasonic sensors will emit sound waves to determine the level of liquid. Whether it is monitoring chemicals in storage tanks or measuring river water levels on bridges, ultrasonic sensors can reach the target (such as water) based on the sound waves and return to the sensor. Time to measure the liquid level.   　　Based on these high-frequency sound waves, ultrasonic sensors output sensor readings, usually in an industry standard sensor format, such as 4-20mA. Ultrasonic sensors are deployed above the liquid to be monitored and are called non-contact sensors. 　　Pressure Sensor 　　In a sense, pressure sensors can measure the pressure or weight of the liquid on the device. They are considered passive sensors, not active sensors. Active sensors such as ultrasonic and radar sensors have their active output for level measurement. signal of. 　　The pressure sensor converts the pressure into the sensor standard protocol (such as 4-20 mA) output signal. Please note that the pressure sensor will be in contact with the body of water being monitored, and a more precise measurement is required at the bottom. 　　For some monitoring scenarios, this may be a challenge because there may be silt or flowing debris in the liquid, which may damage the sensor. In other cases, such as monitoring the water level and depth of the well, the pressure sensor is usually the most effective Water level sensor. 　　Radar level sensor   　　The radar sensor uses a probe to guide the high-frequency radar and electromagnetic waves from the sensor to the water level being monitored. The radar water level sensor will output the water level reading according to the length of time it takes for the radar pulse to return. 　　Generally, radar sensors are more expensive than other types of liquid level sensors. However, the waves and pulses output by the radar sensor can often penetrate things that may interfere with the true measurement level, such as bubbles or vapors. For this reason, you will decide which level sensor or combination of level sensor technology will work best in a particular scenario. 　　Application of Water Level Sensor of Internet of Things in Flood Warning System 　　Most importantly, effective flood warning systems and other water level monitoring systems integrate IoT sensor technology. 　　Smart cities on the east coast of the United States have deployed flood warning systems that use industrial IoT sensors to monitor water levels. Specifically, the ultrasonic and radar water level sensors mentioned above are the most commonly used, as can be seen from the photos of the article.   　　In addition, according to our experience, the sensors in the flood warning system usually use solar panels to supply power, and use mobile phone networks or WiFi to upload sensor information to the cloud. As you know, in the end it all depends on the most effective deployment that each customer really needs. 　　The above is a brief overview of how industrial IoT water level sensors are used in water regime monitoring systems (such as flood warning systems). According to our experience, the Industrial Internet of Things has had a huge positive impact on the water monitoring industry, from well water resources management to flood warning systems!
