ABSTRACT
This design using ultrasonic technology measure level, measuring instruments may not be immersed in the liquid, reduce the instrument and the interaction between liquid, avoid contact with pollution, raise the safety and reliability. Also has high flexibility and adaptability of strong, can always change USES (and measurement, etc) and measurement speed. Ultrasonic ranging, can be applied in automobile reverse construction site, and the position control, also can be used for such as level, deep, pipe length measurement etc. In the measurement range 0.4-8.00 m, measurement accuracy, being measured 1cm measurement with no direct contact with the object can clearly showed stable measurement result. Due to the strong, the energy consumption of ultrasonic directivity slowly in the medium of communication, distance, and is often used to measure the distance of ultrasonic, such as rangefinder and material level measurement instrument etc can all through the ultrasonic. Using ultrasonic detection tend to be quick, convenient, simple, easy to control, and in real-time measuring precision can reach the requirement of practical industrial.
