Summary

SYCW series ultrasonic (liquid) level instrument is a kind of intelligent non-contact measuring instrument. The product has an automatic power adjustment, gain control, temperature compensation, the detection technology and advanced computing technologies, improve the measurement accuracy of the instrument, function to suppress interference of echo, ensure the measurement result is true. The utility model can be widely used for measuring the liquid level and the solid level of various liquids, and can also be used for measuring the distance.

Working principle

The ultrasonic sensor under the control of the microprocessor, transmitting and receiving the ultrasonic, and by the ultrasonic propagation time in t air to calculate ultrasonic sensor and measured the distance of S, due to the acoustic wave propagation in the air velocity C is certain, according to the s=ct/2 s can be calculated, and because the ultrasonic sensor and the bottom of the container the distance H is certain, the measured object matter (liquid) h=H-s.
