Product Description:
The KWL801B-RS485 radar level sensor has been specifically designed to adhere to the standard specifications outlined in national standard DB50/T 826-2017 for level meters. The sensor's core component is designed with a fully sealed IP68 waterproofing, ensuring that it is suitable for use in a range of environments and can withstand heavy rainfall and other harsh environmental conditions.
One of the primary advantages of this product is its long-range capabilities. The maximum measurement range of the sensor extends up to 40 meters, which is a significant advantage for measuring the levels of large tanks or vessels. Furthermore, the sensor has a minimal blind spot of less than 6 cms, which enables users to accurately measure the level of the liquid or material being monitored, even in confined spaces.
Another key feature of the KWL801B-RS485 radar level sensor is its high accuracy. Due to its higher frequency and broader bandwidth, it achieves superior accuracy when compared to other sensors on the market. This makes it an ideal choice for industries where precision and accuracy are crucial, such as manufacturing or chemical processing.
The sensor is also incredibly easy to install. It comes with a fixed bracket that allows for easy and secure installation on tanks or vessels. This ensures that the sensor can be installed quickly and efficiently, which can save businesses time and money.

Dimension:
Installation:
(1) Ensure that the sensor is perpendicular to the medium surface.
(2) Avoid the transmitting beam from irradiating interference objects and generating false echoes.

Applications:
The working principle of radar level sensors is based on the concept of time domain reflection (TDR). In essence, these sensors operate by emitting an electromagnetic pulse that travels along a cable or probe, at the speed of light.
When the electromagnetic pulse encounters the surface of the measured medium that is being monitored, a portion of the pulse is reflected back towards the transmitter of the radar level meter, along the same path it traveled. The time taken for the pulse to travel in both directions is then measured and used to calculate the distance between the transmitter and the surface of the measured medium.
Based on the time-of-flight of the pulse, the radar level sensor can determine and calculate the height of the level being monitored. This information is then sent to the connected monitoring or control system for analysis and decision making based on the specific application requirements.
