Amamitha okugeleza e-Ultrasonic asetshenziswa kabanzi ezimbonini ezahlukene ukukala ukugeleza koketshezi namagesi. Ayaziwa ngokunemba kwawo, ukuthembeka, kanye nokungangenisi, okwenza kube ukukhetha okuthandwayo kwezicelo eziningi. Kunezinhlobo ezimbili eziyinhloko zobuchwepheshe be-ultrasonic flowmeter: indlela yesikhathi sokuthutha kanye nendlela ye-Doppler. Kule bhulogi, sizohlola umehluko phakathi kwalawa buchwepheshe obubili kanye nezinhlelo zabo zokusebenza.
Umgomo osebenzayo wemitha yokugeleza kwe-ultrasonic yesikhathi sokuhamba ukukala isikhathi esithathwayo ukuze isignali ye-ultrasonic isakazeke phezulu naphansi epayipini. Umehluko wesikhathi sokuhamba ulingana nesilinganiso sokugeleza koketshezi. Lobu buchwepheshe bufanele uketshezi oluhlanzekile, olufanayo olunezinhlayiya ezimbalwa noma amabhamuza omoya. Luvame ukusetshenziswa ezicelweni ezifana nokuphathwa kwamanzi namanzi angcolile, izinhlelo ze-HVAC, kanye nezinqubo zezimboni lapho uketshezi lungenazo izinto ezingcolile.
Ngakolunye uhlangothi, amamitha okugeleza e-Doppler ultrasonic asebenzisa umphumela we-Doppler ukukala izinga lokugeleza koketshezi. Lobu buchwepheshe busebenza ngokukhipha izimpawu ze-ultrasonic eziboniswa yizinhlayiya noma amabhamuza oketshezini. Ukushintsha kwemvamisa yesignali eboniswayo bese kusetshenziswa ukubala izinga lokugeleza. Amamitha okugeleza e-Doppler afaneleka uketshezi oluqukethe izinhlayiya ezilengayo noma amabhamuza omoya, okwenza kube ukukhetha kokuqala kokusetshenziswa okubandakanya ama-slurries, amanzi angcolile agcwele izinto eziqinile kanye noketshezi olunomoya.
Omunye wemehluko omkhulu phakathi kwamamitha okugeleza e-ultrasonic ngesikhathi sokuthutha kanye namamitha okugeleza e-Doppler ultrasonic ukuthi afaneleka yini ezinhlotsheni ezahlukene zoketshezi. Nakuba amamitha okugeleza esebenza kahle koketshezi oluhlanzekile nolufanayo, amamitha e-Doppler afaneleka kangcono ukuphatha uketshezi oluqukethe ukungcola noma olunomoya. Lapho ukhetha ubuchwepheshe obufanele bemitha yokugeleza ye-ultrasonic yokusetshenziswa okuthile, kubalulekile ukucabangela izakhiwo zoketshezi olulinganiswayo.
Esinye isici okufanele sicatshangelwe usayizi wepayipi nezinto zokwakha. Amamitha okugeleza e-ultrasonic esikhathi sokuthutha afanelekela izinhlobo ezahlukene zosayizi wepayipi nezinto zokwakha, okuhlanganisa izinsimbi, ipulasitiki kanye nokhonkolo. Ayatholakala kokubili kumapayipi amancane namakhulu anobubanzi, okwenza afaneleke ezindaweni ezahlukene zokufakwa. Amamitha okugeleza e-Doppler, ngakolunye uhlangothi, angase abe nemikhawulo ngobukhulu bepayipi kanye nokuhambisana kwezinto ngoba ukuba khona kwezinhlayiya noma amabhamuza omoya oketshezini kubalulekile ekusebenzeni kwawo.
Ngaphezu kwezici zoketshezi kanye nokucatshangelwa kwamapayipi, ukufakwa nokugcinwa kwemitha yokugeleza kwe-ultrasonic kufanele kucatshangelwe. Nakuba amamitha okuhamba ngokuvamile adinga amapayipi aqondile ukuze kwenziwe izilinganiso ezinembile, amamitha e-Doppler angase akhululeke kakhulu ngokwezidingo zokufakwa ngenxa yekhono lawo lokusebenza lapho kukhona izinhlayiya noma amabhamuza.
Ngamafuphi, ukuqonda zombili izinhlobo zobuchwepheshe be-ultrasonic flow meter (isikhathi sokuguquka kanye ne-Doppler) kubalulekile ekukhetheni ikhambi elifanele lohlelo oluthile. Ngokucabangela uhlobo loketshezi, usayizi wepayipi kanye nezinto, kanye nezidingo zokufakwa nokugcinwa, abasebenzisi bangenza izinqumo ezinolwazi ukuqinisekisa izilinganiso zokugeleza ezinembile nezithembekile. Kungakhathaliseki ukuthi kuqapha ukugeleza kwamanzi ohlelweni lukamasipala noma kulinganisa ukugeleza kwe-slurry enkambisweni yezimboni, ukukhetha phakathi kwamamitha okugeleza e-ultrasonic e-transit time kanye namamitha okugeleza e-Doppler e-ultrasonic kungaba nomthelela omkhulu ekusebenzeni kahle kwekhambi lokulinganisa.
