Introduction
The KWL801B radar water level meter is a reliable and efficient solution for water level monitoring in sewage treatment plants. With a 3 m RS485 output, it offers precise and continuous measurement capabilities. This meter operates by emitting radar waves that interact with the water surface in the sewage treatment plant. The radar waves bounce back and are detected, allowing the meter to calculate the water level accurately. The 3 m range is well-suited for the confined spaces and specific requirements of sewage treatment facilities. The RS485 output enables seamless integration with the plant's existing control and monitoring systems. It provides real-time water level data that is crucial for maintaining proper sewage flow, preventing overflows, and ensuring the effectiveness of the treatment process. By using this meter, operators can optimize the operation of pumps, valves, and other equipment, leading to enhanced overall performance and compliance with environmental regulations.
