Ultrasonic Level Transmitter
The Ultrasonic Level Transmitter is designed to measure the level of all types of liquids using ultrasonic sound waves. The transducer emits ultrasonic pulses toward the liquid surface; the reflected waves are received back, and the electronics compute the distance based on time of flight. The transmitter generates a proportional 4–20 mA signal suitable for controllers or monitoring devices.
It features easy installation, a compact design, an integral 4-digit display, and simple calibration through built-in keys. With a measuring range of up to 10 meters, it provides reliable and accurate performance for industrial applications.

Construction & Working
The system consists of an ultrasonic transducer integrated with microcontroller-based electronics housed in a durable enclosure. The transducer emits ultrasonic pulses toward the service medium; the returning echoes are sensed by the electronics, which convert them into a 4–20 mA output for monitoring and control.
