Suitable for a wide range of liquid level measurement and control applications, Ultrasonic Level meter with 4 to 20 mA output is designed to provide accurate measurements of fluid levels in various environments. Utilizing sound waves, this device delivers reliable data while integrating seamlessly with control systems using 4 to 20 mA current output and RS485 Communication output. this instrument meets the demands of modern industry with unmatched convenience and performance. Additionally, the integrated OLED display features a high-definition, self-illuminating interface, ensuring clear visibility and effortless configuration—even in low-light environments.
The Principle Behind Ultrasonic Measurement
The Ultrasonic Level meter operates on a straightforward yet effective principle. By emitting high-frequency ultrasonic sound waves towards the surface of the liquid, the transmitter measures the time taken for echoes to return. The device calculates the distance based on the speed of sound in air and translates this information into a level measurement.
