The electronic unit of the integrated ultrasonic level meter is integrated with the ultrasonic probe, usually installed on the upper part of the container, with a compact structure and easy installation and debugging. Sensor materials can be selected from ABS, PVDF, PTFE anti-corrosion materials to adapt to harsh industrial application environments. The instrument adopts dynamic power control technology to constrain signal strength and beam angle, and uses unique echo scanning technology to identify real signals. The measurement is accurate, stable, and reliable, and is widely used in various industrial fields.
The HLU series four wire ultrasonic level meter adopts DC24V or AC220V power supply, and outputs DC4-20mA signals and high and low alarm signals.
