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.
