Overview

The RKL-03 Ultrasonic Liquid Level Transmitter is engineered to deliver precise and stable liquid level measurement using advanced ultrasonic sensing technology. By emitting ultrasonic pulses and calculating the time taken for the echo to return from the liquid surface, the device determines the level accurately without physical contact.

This non-contact design makes it particularly suitable for applications involving corrosive, hazardous, or contaminated liquids, as it eliminates sensor wear and reduces maintenance requirements. The transmitter is built with high reliability and strong resistance to environmental interference, ensuring consistent performance even in challenging conditions.

With flexible output options such as 4–20mA and RS485, the device can be easily integrated into existing monitoring and control systems, including data loggers and industrial automation platforms. It also features a user-friendly LCD display and configurable parameters for customized operation.

The RKL-03 is widely used in applications such as water treatment, reservoirs, agricultural irrigation, chemical processing, and urban sewage systems, offering a cost-effective and efficient solution for continuous level monitoring.
