The RKL-03 Ultrasonic Level Transmitter is a reliable, non-contact solution for liquid level measurement, offering easy installation and minimal maintenance. Using the Time-of-Flight (TOF) principle, it measures the distance to the liquid surface by calculating the time between emitted and reflected ultrasonic pulses.
