ZN-CWY seriesUltrasonic level analyzerIt is an intelligent non-contact object (liquid) level measuring instrument. The product has automatic power adjustment, gain control, temperature compensation, and adopts advanced detection and calculation technology to improve the measurement accuracy of the instrument. It also has a suppression function for interference echoes to ensure the authenticity of the measurement results. The product can be widely used for measuring the liquid level of various liquids and the solid level, as well as for measuring distance.
Working principle
Ultrasonic transmissionUnder the control of a microprocessor, the sensor emits and receives ultrasonic waves, and calculates the distance s between the ultrasonic sensor and the object being measured based on the propagation time t of the ultrasonic waves in the air. Since the speed c of sound waves in the air is constant, s can be calculated based on s=ct/2. Also, because the distance H between the ultrasonic sensor and the bottom of the container is constant, the liquid level of the object being measured is h=H-s.
