I-flowmeter ye-Doppler yetshaneli evulekileyo ibhekisa kwi-flowmeter ye-ultrasonic Doppler evulekileyo yetshaneli, xa ithelekiswa ne-flowmeter ye-radar ye-Doppler, inezi nzuzo zilandelayo:
Ukuchaneka okuphezulu kokulinganisa:I-Ultrasonic Doppler open channel flowmeter inokulinganisa isantya sokuhamba kwecandelo lamanzi, esinokubonakalisa ngokuchanekileyo ukusasazwa kwesantya sokuhamba kwecandelo lamanzi liphela, kwaye ukuchaneka kokulinganisa kudla ngokufikelela kwi-±1% okanye ngaphezulu. I-Doppler radar flowmeter ilinganisa isantya sokuhamba komphezulu womzimba wamanzi, nangona isantya sokuhamba komphezulu sinokuguqulwa sibe yisantya sokuhamba esiqhelekileyo secandelo ngemodeli eyakhelwe ngaphakathi, kodwa kwiimeko zokuhamba ezinzima okanye ukusetyenziswa kokuqala kwe-flow check set calibration coefficient, ukuchaneka okuphantsi.
Amandla aqinileyo okuziqhelanisa neemeko ezinzima zokuhamba kwamanzi: Ii-Ultrasonic Doppler open channel flowmeters zifanelekile kwiimeko ezahlukeneyo zokuhamba kwamanzi, kuquka amanzi anodaka, igwebu, kunye nokuhamba kwamanzi okungazinzanga. Ngenxa yokuba isekelwe ekukhanyeni kwamasuntswana axhonyiweyo emanzini ukuya kwi-ultrasound wave ukulinganisa isantya sokuhamba kwamanzi, nokuba kukho ukungcola emanzini, amaqamza, njl.njl., ingasebenza ngcono. I-Doppler radar flowmeter ichaphazeleka kakhulu kukuguquguquka komphezulu wamanzi. Ukuba ukutshintsha komphezulu wamanzi kukhulu, isignali ebonakalisiweyo ye-radar wave ayizinzanga, ngaloo ndlela ichaphazela ukuchaneka kokulinganisa.
Impembelelo encinci kwimozulu: i-flowmeter ye-Doppler evulekileyo efakwe phantsi kwamanzi okanye kwi-channel, engachaphazelekiyo kukutshintsha kwemozulu, njengemvula enkulu, umoya, inkungu, njl.njl., ekuchanekeni kwayo kokulinganisa incinci. I-flowmeter ye-radar ye-Doppler ilinganiswa ngokuhambisa amaza e-radar kumphezulu wamanzi. Iimeko zemozulu zinokuphazamisana nokusasazwa kunye nokubonakaliswa kwamaza e-radar, umzekelo, imvula enkulu inokuphazamisana nesignali ye-radar, kwaye imimoya enamandla iya kwenza kube nzima ukuguquguquka komphezulu wamanzi, ngaloo ndlela ichaphazele ukuchaneka kokulinganisa.
Ifanelekile ukujonga rhoqo ixesha elide: Ngenxa yokuba i-flowmeter ye-Doppler ye-open-channel ayichaphazeleki kangako ziimeko zokusingqongileyo kwaye isebenza kakuhle, ifanelekile ngakumbi ukujonga rhoqo ixesha elide nokuhamba rhoqo kwe-open-channel, nto leyo enokubonelela ngedatha ezinzileyo nethembekileyo. I-flowmeter ye-radar ye-Doppler inokutshintshatshintsha okanye ingachaneki kwiimeko ezithile zemozulu embi okanye iimeko ezikhethekileyo zokusingqongileyo, kwaye uzinzo lokujonga rhoqo ixesha elide luphantsi kancinci.
