I-Doppler ephathwayo ebambayoii-flowmeters ze-ultrasonicukubonelela ngomlinganiselo wokuhamba okungenakuphazamisana owenzelwe ngokukodwa ulwelo olunezimbiwa ezixhonyiweyo okanye amaqamza omoya afakwe ngaphakathi. Endaweni yokusika imibhobho okanye ukumisa imveliso, i-transducer ye-ultrasonic ifakwa nje ngaphandle eludongeni lombhobho wangaphandle, ivumela ukuthunyelwa ngokukhawuleza kwindawo ngaphandle kokuphazamiseka kwenkqubo.
Esi sixhobo sisebenza ngokusekelwe kwisiphumo seDoppler. I-transducer idlulisela amaza e-ultrasonic kulwelo. Xa amaza esandi ebetha amasuntswana axhonyiweyo, iisediment okanye ii-microbubbles ngaphakathi kolwelo, imiqondiso ebonakalisiweyo ivelisa utshintsho lwefrikhwensi. Iyunithi ephambili ephathwayo ibamba olu tshintsho lwefrikhwensi ukuze ibale isantya solwelo, kwaye ibala ngakumbi isantya sokuhamba ngokukhawuleza kunye nomthamo wokuhamba oqokelelweyo. Ngokungafaniyo ne-transit-time ultrasonic flowmeters ezifanelekileyo kumanzi acocekileyo,I-DopplerIzinzwa zixhomekeke kukungcola okubonakalayo kwindawo yokulahla ukungcola, zisebenza kakuhle kakhulu kwilindle, amanzi amdaka emizi-mveliso, udaka, intlama kunye nokungcola kwemigodi.
Inkqubo epheleleyo inesilawuli esiphathwa ngesandla esikhaphukhaphu kunye neprobe yangaphandle eyahlukileyo yokubamba. Abaqhubi banokufikelela kwimisebenzi ethe ngqo ngezitshixo ezibonakalayo kwaye bafunde idatha yexesha langempela ngokucacileyo kwisikrini se-LCD. Ukufakwa kwedatha yangaphakathi kwenza ukuba kuqhubeke ukurekhoda iirekhodi zokuhamba, ezinokuthunyelwa ngaphandle ukuze zihlolwe, zinikwe ingxelo yokuthobela imithetho okanye zichongwe ngemibhobho. Ixhasa izixhobo ezahlukeneyo zemibhobho kuquka i-PVC, i-HDPE, intsimbi yekhabhoni kunye nesinyithi esityhidiweyo, ilungelelanisa nobubanzi bemibhobho obuqhelekileyo kwizicelo zasentsimini.
Enye into ebalulekileyo yale yunithi iphathwayo kukuhambahamba. Iingcali zasentsimini zinokuyithwala ukuze zenze uphando lokuhamba kweendawo, uvavanyo lokuqalisa okwethutyana, ukuhlolwa kokuvuza kunye nokuqinisekiswa kokuhamba okuthelekisayo kwiindawo ezahlukeneyo. Ekubeni kungekho zixhobo zidibana nendawo elinganisiweyo, akukho mngcipheko wokungcola kwesensor, ukukrazuka okanye ukuvaleka, nto leyo enciphisa kakhulu iindleko zokugcinwa rhoqo. Iindleko zomsebenzi kunye nezinto zokufakelwa nazo zigcinwa kakhulu xa kuthelekiswa nezixhobo zokufaka okanye zokuhambisa ngaphakathi.
Ukuqonda ukusetyenziswa ngokufanelekileyo kubalulekile ukuze kufundwe ngokuthembekileyo. Ukuba ulwelo lunezinga eliphantsi kakhulu lamasuntswana, imiqondiso ye-echo eyaneleyo ayinakwenzeka, nto leyo ebangela ukulinganiswa okungazinzi. Isikali semibhobho esigqithisileyo, ulwelo lwerabha oluxineneyo okanye ukungcangcazela okukhulu kwangaphandle nako kuya kunciphisa imiqondiso ye-ultrasonic kwaye kunciphise ukuchaneka.
Njengesisombululo sokujonga okwethutyana esiguquguqukayo, iDoppler ephathekayoii-flowmeters ze-ultrasoniczamkelwe kakhulu ziiarhente zokusingqongileyo, amasebe amanzi amdaka kamasipala, abaqhubi bemigodi kunye neefektri zokucubungula. Ngokulula ukuyilungiselela, ukuphatheka kakuhle kunye nokuziqhelanisa kakuhle nolwelo olungcolileyo, iye yaba zizixhobo ezibalulekileyo zasentsimini zokuhlola ukuhamba kolwelo kwindawo.
