Ngophuhliso olukhawulezileyo lwetekhnoloji yokulinganisa ulwelo lwemizi-mveliso, ii-flowmeters ziye zaba zizixhobo ezibalulekileyo kwi-petroleum, chemical, water delivery, HVAC kunye ne-energy management industry. Phakathi kwezixhobo ezahlukeneyo zokulinganisa ukuhamba, ii-insertion ultrasonic flowmeters zihlukile ngenxa yoyilo lwazo olulodwa, ukusebenza okuthembekileyo kunye nokuziqhelanisa nokusingqongileyo. Zahlukile kwii-flowmeters zemveli ezidityanisiweyo zepayipi kunye ne-external clamp-on.ii-flowmeters ze-ultrasonic, ukufakwa kwe-ultrasonic flowmeters kulinganisela ukuchaneka kokulinganisa, ukulula kokufakela kunye nokuzinza kokusebenza, okwenza ukuba zisetyenziswe ngokubanzi kwiimeko ezinzima zokujonga ulwelo lwemizi-mveliso.
Umgaqo wokusebenza wokufakaii-flowmeters ze-ultrasonicisekelwe kwindlela yokwahluka kwexesha lokuhamba, evuthiweyo nesebenzayo ekufumaneni isantya solwelo. Ezi zixhobo zixhotyiswe ngee-transducers ezimbini ze-ultrasonic ezifakelwayo, ezifakwa kumbhobho nge-engile emiselweyo kunye nomgama omiselweyo. Ii-transducers zinokuthumela kwaye zamkele imiqondiso ye-ultrasonic macala omabini. Xa ii-pulses ze-ultrasonic zisasazeka ngezantsi kwicala lokuhamba kolwelo, isantya sokudlulisa isandi siyanda kwaye ixesha lokusasaza liyafinyela; xa zisasazwa ngokuchaseneisikhokelo sokuhamba, isantya siyancipha kwaye ixesha liyakhula. Imitha ibamba ngokuchanekileyo umahluko omncinci wexesha phakathi kweemeko ezimbini zokusasazeka, kwaye ibala isantya sokuhamba kolwelo ngexesha langempela ngokudibanisa ububanzi bombhobho, i-engile yokukhupha isandi kunye nezinye iiparameter ezimiselweyo. Okokugqibela, i-volumetric ekhawulezileyo neqokelelweyoukuhambaifunyanwa ngokubalwa kwendawo enqamlezileyo yombhobho. Lo mgaqo wokulinganisa ongadibaniyo uthintela ukungqubana ngokuthe ngqo kunye nokuphazamiseka phakathi kwezinto zokulinganisa kunye nolwelo, ubeka isiseko sokusebenza okuzinzileyo nokungalahlekiyo.
Enye yezona zinto zibalaseleyo kwii-insertion ultrasonic flowmeters ziingenelo zazo ezibalaseleyo zokufakela nokugcina. Ngokungafaniyo nee-in-line flowmeters ezifuna ukunqunyulwa kwemibhobho kunye nokuvalwa kwenkqubo ukuze kufakelwe, iimodeli zokufaka zifuna kuphela ukubhola okulula kunye nokufakwa kwe-plug-in kumphezulu wepayipi okhoyo. Yonke inkqubo yokufakela ayichaphazeli ukusebenza okuqhelekileyo kwenkqubo yokuhambisa ulwelo, ifezekisa ukwakhiwa okungayekiyo kwaye iphucula kakhulu ukusebenza kakuhle kokwakha. Kulondolozo lwemihla ngemihla, i-transducer probe inokuqhekeka ngokuzimeleyo, icocwe kwaye ilinganiswe ngaphandle kokuqhaqha umbhobho uphela, nto leyo enciphisa kakhulu iindleko zokugcinwa kamva kunye nokulahleka kwexesha lokungasebenzi kwenkqubo. Olu phawu lwenza ukuba ifaneleke ngakumbi kwiipayipi zoshishino ezifuna ukusebenza okuqhubekayo nokungaphazanyiswa.
Ukuguquguquka okuphezulu kolwelo yenye inzuzo ephambili yolu hloboi-flowmeter. Ayithintelwanga kukukwazi ukuqhuba kwezixhobo ezilinganisiweyo, kwaye inokulinganisa ngokuchanekileyo ulwelo oluhlukeneyo oluqhubayo nolungaqhubiyo, kuquka amanzi empompini, amanzi amdaka emizi-mveliso, ioyile ekrwada, ioyile yepetroli kunye nee-reagents zeekhemikhali. Okwangoku, ineemfuno eziphantsi zokucoceka kolwelo kwaye inokuzivumelanisa nezixhobo eziqulathe inani elincinci lamasuntswana axhonyiweyo. Ngokuphathelele ukulungelelaniswa kwemibhobho, iyahambelana nemibhobho yesinyithi kunye nengeyoyesinyithi yee-calibers ezahlukeneyo, isombulula imida yokulinganisa yemitha yokuhamba yendabuko yemibhobho emikhulu. Ukongeza, izixhobo azinazo izinto ezithintela ukuhamba kwamanzi ngaphakathi, nto leyo ebangela ukuba kungabikho lahleko yoxinzelelo ngexesha lokulinganisa. Olu lwakhiwo lokuhamba kwamanzi olungathintelwanga lunciphisa ngokufanelekileyo ukusetyenziswa kwamandla okuthuthwa kwemibhobho, luhlangabezana neemfuno zokonga amandla kunye nokusebenza ngokufanelekileyo kweenkqubo zanamhlanje zoshishino.
Ngokuphathelele ukusebenza kokulinganisa, ukufakwa kwe-ultrasonicii-flowmetersukufezekisa ibhalansi egqibeleleyo phakathi kokuchaneka okuphezulu kunye nokuzinza okuqinileyo. Ngee-algorithms zokucubungula isignali ezilungiselelwe kakuhle, ukuchaneka kwazo kokulinganisa kunokufikelela kwi-±0.1% yokufunda, kuxhasa ukujonga okuzinzileyo kokuhamba kolwelo ngesantya esiphantsi nangesantya esiphezulu. Imodyuli yokulwa nokuphazamiseka eyakhelwe ngaphakathi inokumelana ngempumelelo nempembelelo yokuphazamiseka kwe-electromagnetic kwimizi-mveliso, ukungcangcazela kwemibhobho kunye notshintsho lobushushu, ukuqinisekisa idatha yokulinganisa engaguqukiyo ixesha elide. Ngaphezu koko, izixhobo zixhasa ukukhutshwa kwedatha ngexesha langempela, ukuhanjiswa okukude kunye nokurekhodwa kwedatha emininzi, okufanelekileyo kulawulo oluzenzekelayo lwemizi-mveliso kunye nohlalutyo lwezibalo zedatha.
Ukuqukumbela, ii-insertion ultrasonic flowmeters zidibanisa ukufakwa okulula, ukuguquguquka ngokubanzi, ukulahleka koxinzelelo olupheleleyo kunye nokuchaneka okuphezulu kokulinganisa. Zilungisa iziphene zemveliumlinganiselo wokuhamba kwamanziizixhobo kwaye zibe zizixhobo ezifanelekileyo zokujonga ukuhamba kolwelo lwemizi-mveliso. Ngokuphuculwa okuqhubekayo kweenkqubo zokujonga ezikrelekrele zemizi-mveliso, olu hlobo lwe-flowmeter luya kuba namathuba abanzi okusetyenziswa kwimveliso yemizi-mveliso, ulawulo lwenethiwekhi yemibhobho yasezidolophini kunye nolawulo lokugcinwa kwamandla.
