Level meter

XG/CW series ultrasonic level meter, integrated ultrasonic level meter. XGCW series ultrasonic material (liquid) level meter is an intelligent non-contact material (liquid) level measuring instrument. The product has automatic power adjustment, gain control, temperature compensation, and adopts advanced detection technology and calculation technology to improve the measurement of the instrument. Accuracy, it has the function of suppressing the interference echo to ensure the authenticity of the measurement results. Ultrasonic level meter can be widely used in the measurement of liquid level and solid level of various liquids.

●Working principle:

Under the control of the microprocessor, the ultrasonic sensor transmits and receives ultrasonic waves, and the distance S between the acoustic sensor and the measured object is calculated by the propagation time of the ultrasonic wave in the air. Since the speed C of the sound wave in the air is constant, then According to: S - Ct /2, S can be calculated, and because the distance H between the ultrasonic sensor and the bottom of the container is constant, the object (liquid) level of the measured object is H = H - S .
