Introduction
The KWL801B radar water level meter is a powerful tool for river level monitoring. With a 10 m RS485 output, it offers reliable and accurate readings. It functions by emitting radar beams towards the river's surface. These beams bounce back upon hitting the water, and the meter calculates the time taken for this round trip to determine the water level precisely. The 10 m range is suitable for many riverine applications, allowing it to capture a significant portion of the river's vertical profile. The RS485 output facilitates seamless connection with data acquisition systems and control centers. This enables real-time monitoring and analysis of river levels, which is crucial for flood prediction and prevention. It helps authorities take proactive measures to protect nearby communities and infrastructure. Additionally, the meter's robust design ensures it can withstand the harsh outdoor conditions typically associated with river environments, such as varying temperatures, humidity, and potential debris in the water.
