Description
Overview
GAOTek the signal output ultrasonic level meter switch is installed on the top of the container. Under the control of the electronic unit, the probe sends a beam of ultrasonic pulse to the measured object. The sound wave is reflected by the surface of the object, and part of the reflected echo is received by the probe and converted into an electrical signal. The change of the level is determined according to the time difference from ultrasonic re transmission to re reception and the known sound speed. The electronic device processes the microwave signal and finally converts it into an electrical signal related to the level.
Features
- Design, excellent performance, simple structure, and easy installation
- Ultrasonic with a small-angle probe for high transmission power & sensitivity
- Customizable limits and alarms for precise liquid level control
