Iimitha zokuhamba nge-ultrasonic zisetyenziswa kakhulu kumashishini ahlukeneyo ukulinganisa ukuhamba kolwelo kunye neegesi. Zaziwa ngokuchaneka kwazo, ukuthembeka, kunye nokungangenisi, nto leyo eyenza ukuba zibe lukhetho oludumileyo kwiizicelo ezininzi. Kukho iintlobo ezimbini eziphambili zobuchwepheshe be-ultrasonic flowmeter: indlela ye-transit-time kunye nendlela ye-Doppler. Kule bhlog, siza kujonga umahluko phakathi kwezi teknoloji zimbini kunye nokusetyenziswa kwazo.
Umgaqo osebenzayo wemitha yokuhamba kwe-ultrasonic yexesha lokuhamba kukulinganisa ixesha elithathwayo ukuze isignali ye-ultrasonic isasazeke phezulu nasezantsi kwipayipi. Umahluko kwixesha lokuhamba uhambelana nesantya sokuhamba kolwelo. Le teknoloji ifanelekile kulwelo olucocekileyo, olufanayo olunamaqhekeza ambalwa okanye amaqamza omoya. Isetyenziswa rhoqo kwizicelo ezifana nolawulo lwamanzi kunye namanzi amdaka, iinkqubo ze-HVAC, kunye neenkqubo zoshishino apho ulwelo lungenazo izinto ezingcolileyo.
Kwelinye icala, iiDoppler ultrasonic flow meter zisebenzisa i-Doppler effect ukulinganisa isantya sokuhamba kolwelo. Le teknoloji isebenza ngokukhupha imiqondiso ye-ultrasonic ebonakaliswa ziisuntswana okanye amaqamza kulwelo. Utshintsho lwemvamisa yesignali ebonakalisiweyo emva koko lusetyenziselwa ukubala isantya sokuhamba. IiDoppler flowmeters zifanelekile kulwelo olunezisuntswana ezixhonyiweyo okanye amaqamza omoya, nto leyo eyenza ukuba zibe lukhetho lokuqala lokusetyenziswa oluquka i-slurry, amanzi amdaka agcwele izinto eziqinileyo kunye nolwelo oluvuthelweyo.
Omnye womahluko ophambili phakathi kweemitha zokuhamba nge-ultrasonic zexesha lokuhamba kunye neemitha zokuhamba nge-ultrasonic ze-Doppler kukufaneleka kwazo kwiintlobo ezahlukeneyo zolwelo. Nangona iimitha zokuhamba zisebenza kakuhle kulwelo olucocekileyo nolufanayo, iimitha ze-Doppler zilungele ngakumbi ukuphatha ulwelo oluqulethe ukungcola okanye olunomoya. Xa ukhetha iteknoloji yemitha yokuhamba nge-ultrasonic efanelekileyo kwisicelo esithile, kubalulekile ukuqwalasela iimpawu zolwelo olulinganiswayo.
Enye into ekufuneka iqwalaselwe bubungakanani bepayipi kunye nezinto ezisetyenziswayo. Iimitha zokuhamba ze-ultrasonic zexesha lokuhamba zilungele iintlobo ngeentlobo zeepayipi kunye nezinto ezisetyenziswayo, kuquka iintsimbi, iiplastiki kunye nekhonkrithi. Ziyafumaneka kwiipayipi ezincinci nezinkulu, nto leyo eyenza zifaneleke kwiindidi ezahlukeneyo zokufakelwa. Iimitha zokuhamba zeDoppler, kwelinye icala, zinokuba nemida kubungakanani bepayipi kunye nokuhambelana kwezinto kuba ubukho beesuntswana okanye amaqamza omoya kulwelo bubalulekile ekusebenzeni kwazo.
Ukongeza kwiimpawu zolwelo kunye nokuqwalaselwa kwemibhobho, ukufakelwa kunye nokugcinwa kwemitha yokuhamba kwe-ultrasonic kufanele kuthathelwe ingqalelo. Nangona iimitha zokuhamba zihlala zifuna imibhobho ethe tye ukuze kwenziwe imilinganiselo echanekileyo, iimitha zeDoppler zinokukhululeka ngakumbi ngokweemfuno zokufakelwa ngenxa yokukwazi kwazo ukusebenza xa kukho amasuntswana okanye amaqamza.
Ngamafutshane, ukuqonda zombini iintlobo zobuchwepheshe be-ultrasonic flow meter (ixesha lotshintsho kunye ne-Doppler) kubalulekile ekukhetheni isisombululo esifanelekileyo kwisicelo esithile. Ngokuqwalasela uhlobo lolwelo, ubungakanani bombhobho kunye nezinto, kunye neemfuno zokufakela kunye nokugcinwa, abasebenzisi banokwenza izigqibo ezinolwazi ukuqinisekisa ukulinganiswa kokuhamba kwamanzi ngokuchanekileyo nangokuthembekileyo. Nokuba kujongwa ukuhamba kwamanzi kwinkqubo kamasipala okanye kulinganiswa ukuhamba kodaka kwinkqubo yemizi-mveliso, ukhetho phakathi kweemitha zokuhamba kwe-ultrasonic zexesha lokuthutha kunye neemitha zokuhamba kwe-ultrasonic ze-Doppler lunokuba nefuthe elikhulu ekusebenzeni kwesisombululo sokulinganisa.
