Ultrasonic Liquid Level Sensor – Non-Contact Measurement

The RKL-03 Ultrasonic Liquid Level Transmitter is a non-contact, high-accuracy solution for liquid and bulk material level measurement. Using ultrasonic pulse technology, the sensor calculates the distance between its antenna and the surface of the measured medium—delivering real-time, maintenance-free monitoring.

With no direct contact required, the RKL-03 is ideal for applications involving corrosive, viscous, or hazardous substances. Built for easy installation and long-term durability, it’s widely used in water tanks, wastewater systems, silos, and industrial reservoirs. Compatible with the RK600-01 data logger or standard recording instruments for seamless data tracking.
