Ultrasonic open channel flowmeterszisetyenziswa kwimijelo yophambukiso lonikezelo lwamanzi ezidolophini, kwiziko lombane lokupholisa umjelo wamanzi ophambukiso kunye nemijelo yokuthuthwa kwamanzi, imijelo yokungena nokucoca ugutyulo, ulwelo lwekhemikhali, nokukhutshelwa kwamanzi amdaka amashishini nemigodi, kunye neeprojekthi zogcino lwamanzi kunye nemijelo yokunkcenkceshela yezolimo.
Ikakhulu ukwenzela ukuba wenze le ngcaciso ilandelayo yokhuseleko lofakelo lwe-ultra-declared channel flowmeter, khumbula ukuyiqokelela ukuba uyayifuna.
1. Isantya sokuhamba esilinganisiweyo sisekelwe kwisiseko sokuba iphethini yokuhamba komjelo iphuhliswe ngokupheleleyo, oko kukuthi, icandelo elichanekileyo lombhobho (umbhobho) lifunekayo ukuhlangabezana neemfuno.
2. Xa icandelo elithe ngqo kwi-site lingonelanga, impembelelo ye-diagonal flow echanekileyo yokulinganisa i-flow velocity kufuneka ihlawulwe ngokuseta ijelo lesandi kulo lonke icandelo lokulinganisa.
3. Ukuba kukho i-weirs, amasango, kunye nezinye izixhobo ngaphambi nangemva kwecandelo lokulinganisa kwi-site ukwenza i-vertical flow turbulent, indlela yokulinganisa i-multi-channel kufuneka isetyenziswe ukulinganisa ngokuchanekileyo umyinge wesantya somphezulu. Inani lemijelo yesandi kunye nokuphakama kwemijelo yesandi kumiselwa ngokweemfuno zokuchaneka komlinganiselo, kunye nenqanaba eliphantsi lamanzi, inqanaba eliphezulu lamanzi, kunye nenqanaba lamanzi asebenzayo kufuneka kuqwalaselwe.
4. Kwiimitha zokuhamba komjelo, kubalulekile ukulinganisa ngokuchanekileyo izinga lokuhamba kunye nomgangatho wamanzi, kodwa impazamo yendawo ye-channel cross-sectional idla ngokuba yimpembelelo enkulu kumlinganiselo wokuhamba (umzekelo, i-sedimentation ezantsi komjelo. , udonga lwetshaneli olungalinganiyo, kunye nobubanzi betshaneli obungahambelaniyo kunye nezinye iimpazamo). Ke ngoko, okucetywayo ngokuthe ngqo apha kukuba ulawulo lwempazamo yendawo enqamlezileyo yomjelo kufuneka luqale ngoyilo lwasekuhlaleni.
Olunye ukhetho lwemitha yokuqukuqela ye-ultrasonic:
