One of the best ways to avoid flood disaster is to use ultrasonic water level sensor to monitor the change of dam level. In fact, the throw in type level sensor can also monitor the level of a dam, because it cannot collect large data and "respond" to changes in the level timely due to its design structure and traditional measurement principles. Therefore, wireless liquid level solution has gradually become a dam level sensor. Its wide application has made a significant contribution to the prevention of floods and droughts, greatly reducing the damage of natural disasters, and thus improving economic development.

More and more water workers are beginning to pay attention to remote tamping and remote level monitoring. The ultrasonic water level sensor not only provides effective protection for dam level monitoring, but also provides technical support for environmental monitoring. As is known to all, the reservoir has the function of flood control and ensuring the balance of water resources. Once a flood disaster occurs, not only will the local economy suffer losses, but more importantly, it will destroy the ecological environment and have a devastating impact on the soil and farmland. In order to avoid natural disasters, water conservancy workers usually use ultrasonic water level sensors to monitor the dam level and understand the water level changes in advance so that they can make timely judgments and give solutions to avoid major natural disasters. Secondly, the use of ultrasonic water level sensors to monitor the dam level has the following reasons: First, reduce the labor intensity and improve work efficiency. Second, intuitive readings to understand water level changes in real time. Third, remote water level monitoring, knowing the flood information in advance. The above advantages are not achievable with input sensors. This is why I recommend an ultrasonic water level sensor to monitor the dam level.

The ultrasonic water level sensor is also insufficient because it is designed based on ultrasonic wave and wireless liquid level monitoring, and the price is relatively expensive. Secondly, because the ultrasonic wave needs to complete data acquisition and execute control commands through the computer, the operator needs skilled computer operation and professional sensor knowledge. But I believe that with the increasing popularity of ultrasonic water level sensors, it can be used for a variety of water (liquid) position monitoring at a cost-effective price.
