Abstract : According to difficult measurement of combustible explosive chemic2substance liquid2level and correla2 tive quantity ,a set of ultrasonic liquid2level sensor based on ADμC812 chip for far2distance ,large2range and non2 contact liquid2level measuring is designed. The sensor has the advantage of? elf2plus ,programmable ,fine expansi2
bility ,which can measure the liquid2level of all mediums whose boiling point is higher than deposited tempera2 ture. It has well referenced value on the intelligentized realization and far2distance measuring of other analogous sensor.
Key words : liquid2level sensor ; ultrasonic ; far2distance measuring ; large2range
