Uma kulinganiswa ukugeleza koketshezi, amamitha okugeleza e-ultrasonic ayisinqumo esithandwayo ngenxa yokunemba kwawo kanye nokungabi yingozi. Kodwa yini ngempela ehlanganiswa yimitha yokugeleza ye-ultrasonic? Ake sibheke ngokucophelela izingxenye ezakha le divayisi entsha.
Inzwa: Ingqikithi ye-ultrasonic flowmeter yinzwa. Lezi yizingxenye eziphethe ukudlulisa nokwamukela izimpawu ze-ultrasonic. Ngokuvamile, kusetshenziswa ama-transducer amabili, elinye lisebenza njengomthumeli kanti elinye njenge-receiver. Njengoba uketshezi lugeleza ngepayipi, i-transducer ikhipha isignali ye-ultrasonic, edlula oketshezini bese ithathwa yi-receiver. Ngokulinganisa isikhathi esithathwayo ukuze isignali ihambe phakathi kwezinzwa, izinga lokugeleza koketshezi lingabalwa ngokunembile.
Iprosesa yesignali: Isignali etholwe yinzwa icutshungulwa yiprosesa yesignali, okuyingxenye ebalulekile yemitha yokugeleza kwe-ultrasonic. Iprosesa ihlaziya umehluko wesikhathi phakathi kwezibonakaliso ezithunyelwe nezamukelwe bese isebenzisa lolu lwazi ukubala ijubane loketshezi. Le datha yejubane isetshenziswa ukunquma izinga lokugeleza koketshezi ngepayipi.
Ukuboniswa Nokuphuma: Amamitha amaningi okugeleza kwe-ultrasonic afakwe iyunithi yokubonisa enikeza idatha yesikhathi sangempela ngesivinini sokugeleza, ijubane kanye nezinye izilinganiso ezifanele. Lokhu kuvumela opharetha ukuthi aqaphe ukugeleza koketshezi futhi enze noma yiziphi izinguquko ezidingekayo. Ngaphezu kwalokho, amamitha okugeleza kwe-ultrasonic avame ukuba nezinketho zokukhipha, njengezimpawu ze-analog noma zedijithali, ezingasetshenziswa ukudlulisa idatha yokugeleza kudivayisi noma ohlelweni lwangaphandle ukuze kuhlaziywe futhi kuqoshwe okwengeziwe.
Ubuchwepheshe Bokudlulisa Nokusebenzisa Ama-Doppler: Amamitha okugeleza e-Ultrasonic angasebenzisa ubuchwepheshe obubili obuhlukene ukukala ukugeleza: ukudlulisa kanye ne-Doppler. Amamitha okugeleza e-Ultrasonic esikhathi sokuthutha afaneleka kakhulu kuketshezi oluhlanzekile, olufana futhi athembele esikhathini esithathayo ukuze isignali ye-ultrasonic ihambe iye phezulu naphansi ngepayipi. Amamitha okugeleza e-Ultrasonic e-Doppler, ngakolunye uhlangothi, afanele uketshezi oluqukethe izinhlayiya noma amabhamuza, futhi alinganisa ukushintsha kwemvamisa yesignali ye-ultrasonic njengoba ixhumana nezinhlayiya ezihambayo kuketshezi.
Ihadiwe Yokufaka Amapayipi: Ukuqinisekisa ukulinganisa okunembile, amamitha okugeleza e-ultrasonic adinga ihadiwe efanele yokufaka ukuze anamathisele inzwa ngokuphephile epayipini. Le hadiwe yenzelwe ukunciphisa ukuphazamiseka kwesignali nokuqinisekisa ukuthi isignali ye-ultrasonic idlula oketshezini ngaphandle kwesithiyo.
Ukunikezwa kwamandla: Okokugcina kodwa okungabalulekile, amamitha okugeleza e-ultrasonic adinga ukunikezwa kwamandla okuthembekile ukuze asebenze. Lokhu kungaba ngesimo sebhethri lamadivayisi aphathekayo, noma uxhumano oluqondile lukagesi lokufakwa unomphela.
Ngamafuphi, imitha yokugeleza ye-ultrasonic ifaka inzwa, iprosesa yesiginali, izinketho zokubonisa nokukhipha, isikhathi sokuhamba noma ubuchwepheshe be-Doppler, ihadiwe yokufaka amapayipi, kanye nokunikezwa kwamandla. Ukuqonda izingxenye zemitha yokugeleza ye-ultrasonic kubalulekile ekuqinisekiseni izilinganiso zokugeleza ezinembile nezithembekile ezinhlobonhlobo zezicelo zezimboni nezentengiselwano.
