A non-reference detection method of the external ultrasonic liquid level switch using the PZT
نویسندگان
چکیده
Oil tank level is an important control parameter in oil depot management. According to the principle that liquid can absorb guided wave propagation energy wall, this paper studied a non-reference detection method of external ultrasonic switch based on signal change value between current and previously signal. The experimental results show with center frequency 30 kHz sensitive low misjudgment detection. setup, judgment threshold set 0.9890. influence wall decreases increase. Finally, effectiveness proposed verified diesel tank. research provides for technology, idea measurement wave.
