I. Izimo ze-Hydraulic
A. Ukugeleza Kwezingxabano
Ukugeleza okuguquguqukayo kuyinkinga evamile ezinhlelweni zeziteshi ezivulekile. Uma ukugeleza kuguquguqukayo, ijubane loketshezi liyahlukahluka ngokungahleliwe ngobukhulu kanye nesiqondiso ngaphesheya kwengxenye yesiteshi.Ama-flowmeter esiteshi avulekile, ikakhulukazi lezo ezithembele ezindleleni zejubane - indawo (njenge-ultrasonic noma i-electromagnetic open channel flowmeters), zithatha iphrofayili yokugeleza ezinzile futhi ebikezelwayo ukuze kulinganiswe ngokunembile. I-Turbulence iyaphazamisa lokhu kucabanga. Isibonelo, emfuleni onephansi elibi noma esiteshini esinezinguquko ezisheshayo ku-geometry, ukwakheka kwama-eddies nama-swirls kungabangela ijubane lokugeleza ezindaweni ezahlukene ukuthi lihluke kakhulu enanini elimaphakathi elilindelwe yi-flowmeter. Ngenxa yalokho, ijubane elilinganisiwe lingase lingameli ngokunembile izinga lokugeleza lilonke, okuholela ekufundweni okungalungile.
B. Ukwehluka Kokujula Kokugeleza
Ukuguquguquka kokujula kokugeleza nakho kungaba yizinkingaama-flowmeter esiteshi esivulekile. Ama-flowmeter amaningi, njenge-weirs kanye ne-flumes, aklanyelwe ukukala izinga lokugeleza ngokusekelwe ebuhlotsheni obuthile phakathi kokujula kokugeleza kanye nokuphuma kwamanzi. Uma ukujula kokugeleza kushintsha ngokushesha noma ngokungahleliwe, lobu budlelwano bungase bungasasebenzi. Ezinhlelweni zokukhipha amanzi emvula, isibonelo, imvula enkulu engazelelwe ingabangela ukwanda okukhulu kokujula kokugeleza. Uma i-flowmeter ingalinganiswanga ukuze ilandise izinguquko ezinjalo zokujula okusheshayo nokukhulu, ingase ibale kabi izinga lokugeleza. Ngaphezu kwalokho, ukuba khona kwamagagasi noma ukukhuphuka kwesiteshi kungenza kube nzima kakhulu ukulinganisa ukujula kokugeleza, njengoba i-flowmeter ingarekhoda amanani okujula angahambisani, okuholela ekubalweni kwezinga lokugeleza okungafanele.
II. Izici Zesiteshi
A. Ukungalungi Kwesiteshi
Iziteshi zemvelo zivame ukuba nezimo ezingavamile zokuwela, ezinobubanzi, ukujula, kanye nemithambeka ehlukahlukene. Iziteshi ezenziwe ngabantu zingase zikhule ngokungajwayelekile ngokuhamba kwesikhathi ngenxa yokugcwala kwenhlabathi, ukuguguleka, noma umonakalo wesakhiwo.Ama-flowmeter esiteshi avulekilengokuvamile zilinganiswa ukuze kusetshenziswe amajiyometri eziteshi ezijwayelekile, ajwayelekile. Uma zifakwe eziteshini ezinezingxenye ezingavamile zokuwela, ukusatshalaliswa kokugeleza kuba yinto engalingani, futhi i-flowmeter ingase ingakwazi ukukala ngokunembile ijubane elimaphakathi noma indawo yokuwela. Isibonelo, emseleni lapho inhlabathi iqoqene khona ohlangothini olulodwa, ukugeleza kuzophambuka, futhi i-flowmeter ingase idlule - noma inciphise izinga lokugeleza kuye ngokuthi indawo yayo ngaphakathi kwesiteshi.
B. Ubulukhuni Bomphezulu
Ubulukhuni bomphezulu wesiteshi buthinta ukumelana kokugeleza kanye nokusatshalaliswa kwejubane ngaphakathi kwesiteshi. Ubuso obuqinile, njengalobo bomsele ogcwele amatshe noma emfudlaneni wemvelo onamatshe nezitshalo, bubangela ukungqubuzana okukhulu njengoba uketshezi lugeleza. Lokhu kungqubuzana kunciphisa ijubane lokugeleza eduze kwemingcele yesiteshi futhi kungaholela kuphrofayili yejubane elingeyona i-logarithmic, ehlukile kuphrofayili efanele ecatshangwa ngabaningi.ukulinganisa ukugeleza kwesiteshi okuvulekileizindlela. Ama-flowmeter ancike ekucabangeni kwephrofayili ethile yejubane, njengamanye ama-flowmeter e-ultrasonic Doppler, angase akhiqize imiphumela enganembile lapho ukugoba kobuso besiteshi kungabalwa kahle. Ukugoba kobuso okwandisiwe nakho kungabangela ukuphazamiseka okwengeziwe, okwenza inqubo yokulinganisa ukugeleza ibe nzima nakakhulu.
III. Ukuphazamiseka Kwangaphandle
A. Udoti kanye nezitshalo
Udoti, njengamagatsha, amaqabunga, kanye nodoti, kanye nezitshalo ezikhule kakhulu ngaphakathi noma eduze komsele, kungaphazamisa ukusebenza kwe-ama-flowmeter esiteshi esivulekile. Kuma-flowmeter e-ultrasonic, udoti kanye nezitshalo kungavimba indlela yezibonakaliso ze-ultrasonic, kungaba ngokumunca noma ukubonakalisa amagagasi. Lokhu kuphazamiseka kungaholela ekwamukelweni kwesignali okungalungile kanye nokuchazwa kabi kwejubane lokugeleza. Endabeni yama-flowmeter omshini, njenge-flowmeter yohlobo lwe-propeller, udoti ungabanjwa ezingxenyeni ezihambayo, okubangela ukuthi imitha ijame noma ijikeleze ngesivinini esingalungile. Ukukhula kwezitshalo eduze kobuso bamanzi nakho kungathinta ukulinganiswa kokujula kokugeleza, njengoba kungadala isikhombikubona samanzi nomoya esingalingani esidida amadivayisi okuzwa ukujula.
B. Izici Zemvelo
Izici zemvelo ezifana nemimoya enamandla kanye nokushintshashintsha kwezinga lokushisa kungathintai-flowmeter yesiteshi esivulekileukusebenza. Imimoya enamandla ingadala amaza ebusweni bamanzi eziteshini ezivulekile. Lawa maza angabangela ukuguquguquka ekujuleni kokugeleza okulinganisiwe, ikakhulukazi kuma-sensor athembele ekutholakaleni kwezinga lomhlaba. Izinguquko zokushisa zingathinta izakhiwo zomzimba zoketshezi, njengobuningi balo kanye ne-viscosity. Kumamitha okugeleza asebenzisa isivinini somsindo oketshezini ukuze alinganiswe (isb., ama-flowmeter e-ultrasonic), izinguquko ekushiseni koketshezi zingashintsha isivinini somsindo, okuholela emaphutheni ekulinganisweni kwejubane. Ezimweni ezibandayo, ukwakheka kweqhwa esiteshini nakho kungaba yinkinga enkulu, njengoba kungavimba imitha yokugeleza noma kushintshe izici zokugeleza ngaphakathi esiteshini.
Ekuphetheni, izici ezahlukahlukene ezihlobene nezimo ze-hydraulic, izici zesiteshi, kanye nokuphazamiseka kwangaphandle kungabangelaama-flowmeter esiteshi esivulekileukunikeza izilinganiso ezinganembile. Ukuqonda nokubhekana nalezi zici kubalulekile ukuqinisekisa ukusebenza okuthembekile kwezinhlelo zokulinganisa ukugeleza kwesiteshi esivulekile.
