IiDoppler ultrasonic flowmetersziye zavela njengezixhobo eziyimfuneko kumacandelo amaninzi, ngenxa yokukwazi kwazo ukulinganisaukuhamba kolwelongokungangenisi nzulu nangokuchanekileyo, nokuba kwiimeko ezinzima. Ukusebenza kwazo kusekelwe kwisiphumo seDoppler, apho ukutshintsha rhoqo kwamaza e-ultrasonic kubonakalisa amasuntswana ahambayo okanye amaqamza kulwelo kusetyenziswa ukubala isantya sokuhamba kwamanzi. Oku kuguquguquka kuzenza zilungele uluhlu olwahlukeneyo lwezicelo.
Kwishishini lokunyanga amanzi namanzi amdaka, iiDoppler ultrasonic flowmeters zidlala indima ebalulekileyo. Zisetyenziselwa ukujonga ukuhamba kwamanzi amdaka angavuthwanga, adla ngokuba nezinto eziqinileyo ezixhonyiweyo, inkunkuma, kunye namanqanaba ahlukeneyo e-viscosity. IiDoppler flowmeters zemveli zinokuvaleka okanye zonakaliswe zizinto ezinjalo, kodwa iiDoppler meters, ngoyilo lwazo olungaphazamisiyo, zinokufakwa ngaphandle kwimibhobho, ziphephe ukudibana ngqo nolwelo. Oku kuvumela ukulinganisa okuqhubekayo nokuthembekileyo, kunceda abaqhubi ukuba baphucule iinkqubo zonyango, baqinisekise ukuba bayahambelana nemigangatho yolawulo, kwaye balawule imithombo yamanzi ngokufanelekileyo. Umzekelo, banokulandela ukuhamba kokungena nokuphuma kwiitanki ze-sedimentation, baqinisekise ukuba amanqanaba onyango asebenza ngomthamo ofanelekileyo.
Icandelo leoyile negesi nalo lizuza kakhulu kwezi flowmeters. Kwimisebenzi ephezulu, zisetyenziselwa ukulinganisa ukuhamba kwamanzi amaninzi (umxube weoyile, igesi, namanzi) kwimibhobho. La manzi adla ngokuxinana kwaye aqulathe izinto eziqinileyo, nto leyo eyenza ukuba umlinganiselo ochanekileyo ube nzima. IiDoppler ultrasonic flowmeters zinokujongana nale meko, zibonelela ngedatha yexesha langempela malunga namazinga okuhamba kwamanzi anceda ekulawuleni amachibi, ukuvavanya imithombo, kunye nokwenza ngcono imveliso. Kwimisebenzi ephakathi nasezantsi, zijonga ukuhamba kweoyile ekrwada, iimveliso ezicociweyo, kunye negesi yendalo kwimibhobho, ziqinisekisa ukuthuthwa okusebenzayo kunye nokuthintela ukuvuza. Ukukwazi kwazo ukusebenza ngamanzi anoxinzelelo oluphezulu kunye nobushushu obuphezulu kongeza ekuthandeni kwazo kweli shishini.
Kwiindawo zokucubungula iikhemikhali, apho ulwelo lunokuba yingozi, lube netyhefu, okanye lube namanqanaba aphezulu ezinto eziqinileyo ezixhonyiweyo, iiDoppler ultrasonic flowmeters ziyindlela ethembekileyo yokukhetha. Zisetyenziselwa ukulinganisa ukuhamba kweekhemikhali ezahlukeneyo, ezinje ngee-asidi, iziseko, kunye ne-slurry, ngexesha leenkqubo zemveliso. Indlela engangeneleli ngayo le mitha isusa umngcipheko wongcoliseko kwaye inciphisa iindleko zokugcina, njengoko kungekho zixhobo zishukumayo okanye izinto ezimanzi ezinokubola okanye ziguge. Oku kuqinisekisa ukulinganiswa ngokuchanekileyo nakwiindawo ezinobundlongondlongo, kunceda abaqhubi bezityalo bagcine umgangatho wemveliso, balawule amazinga okuphendula, kwaye baqinisekise ukhuseleko.
Ishishini lokutya neziselo lelinye icandelo apho iiDoppler ultrasonic flowmeters zifumana khona ukusetyenziswa. Zisetyenziselwa ukulinganisa ukuhamba kolwelo olufana nobisi, ijusi, isiraphu, kunye neesosi, ezinokuba namasuntswana afana ne-pulp, imbewu, okanye izinto eziqinileyo. Ukufakelwa okungangenisi manzi kuqinisekisa ukuba ulwelo alungcoliswanga, luthobela imigangatho yococeko engqongqo. Ezi flowmeters zinceda ekulawuleni ukuhamba kolwelo ngexesha lokuxuba, ukuxuba, kunye neenkqubo zokuzalisa, ukuqinisekisa umgangatho wemveliso ohambelanayo kunye nokunciphisa inkunkuma. Umzekelo, kwisityalo sokwenza ijusi, zinokujonga ukuhamba kwejusi kwiibhotile, ukuqinisekisa ukuba ibhotile nganye izaliswe ngobuninzi obuchanekileyo.
Kwimisebenzi yokwemba, iiDoppler ultrasonic flowmeters zisetyenziselwa ukulinganisa ukuhamba kwe-slurry, eziyimixube yamanzi kunye namasuntswana aqinileyo afana ne-ore, isanti, kunye negravel. Ii-slurry ziyarhabaxa kwaye zinokubangela ukuguguleka okukhulu kwii-flowmeters zemveli. IiDoppler meters, ngokuxhonywa kwazo ngaphandle, ziyayiphepha le ngxaki, zibonelela ngokuthembeka kwexesha elide. Zinceda ekujonganeni nokuhamba kwe-slurry kwimibhobho esetyenziselwa ukuthutha izimbiwa, ukulawula idosi yeekhemikhali ekucutshungulweni, kunye nokulawula ukusetyenziswa kwamanzi kwimisebenzi yokwemba. Ukulinganisa ukuhamba ngokuchanekileyo kubalulekile ekwenzeni ngcono ukusebenza kweenkqubo zokwemba kunye nokunciphisa iindleko zokusebenza.
Ukongeza, kwezolimo, iiDoppler ultrasonic flowmeters zisetyenziselwa ukulinganisaukuhambayamanzi okunkcenkceshela kwimibhobho. Zinceda abalimi ukuba bajonge ukusetyenziswa kwamanzi, ukuqinisekisa ukuba izityalo zifumana amanzi afanelekileyo, nto leyo ibalulekileyo ekulondolozweni kwamanzi nasekunyuseni isivuno sezityalo. Zingasetyenziselwa ukulinganisa ukuhamba kwezichumisi kunye nezibulali-zinambuzane kwiinkqubo zokunkcenkceshela, ukuqinisekisa ukusetyenziswa ngokuchanekileyo.
Ukuququmbela,IiDoppler ultrasonic flowmetersziye zabonakalisa ixabiso lazo kumashishini amaninzi, ukusuka kunyango lwamanzi kunye neoyile negesi ukuya ekucutshungulweni kwamakhemikhali, ukutya neziselo, imigodi, kunye nezolimo. Ukukwazi kwazo ukujongana neemeko ezinzima zolwelo, uyilo olungaphazamisiyo, kunye nokulinganisa ngokuchanekileyo kuzenza zibe sisixhobo esibalulekileyo sokwenza ngcono iinkqubo, ukuqinisekisa ukuthotyelwa kwemithetho, kunye nokunciphisa iindleko. Njengoko ubuchwepheshe buqhubeka buhambela phambili, ezi flowmeters zinokufumana usetyenziso oluninzi kumacandelo ahlukeneyo, nto leyo ephucula ngakumbi ukubaluleka kwazo kwimisebenzi yemizi-mveliso.
