Xa kuthelekiswa nezinye iintlobo zee-flowmeters ze-ultrasonic, i-clamp yangaphandle ye-ultrasonic flowmeter ineenzuzo ezingenakuqhathaniswa.Ngokomzekelo, i-clamp yangaphandle yohlobo lwe-ultra-side flowmeter ingafaka i-probe kwindawo yangaphandle yombhobho, ukwenzela ukuba ukuhamba kungaphulwa kwaye ukuhamba kulinganiswa ngesiseko sokungaphulwa kombhobho.Ukongeza, ilahleko yoxinzelelo lwayo iphantsi, phantse i-zero, kwaye ikwanenzuzo enkulu ngokwexabiso kwimakethi ye-ultrasonic flowmeter ye-diameter enkulu, kwaye ifumene indumiso eninzi yabathengi.
Nangona kunjalo, enyanisweni, kwinkqubo yokusetyenziswa kwangempela kwe-clamp yangaphandle ye-ultrasonic flowmeter, kuya kuba nezizathu zempendulo yokulinganisa engachanekanga kubathengi.Enyanisweni, le meko isoloko umsebenzisi kwinkqubo yokuhlohla ngoyaba ezi ngxaki, namhlanje kudweliswe enye yazo ukukuchazela.
I-external clamped kwi-flowmeter ye-ultrasonic ayiqinisekiswanga ngokuchanekileyo okanye ilinganiswe, kwaye kufuneka sazi ukuba nayiphi na i-flowmeter idinga ukuqinisekiswa okanye ukulinganisa ngaphambi kokusetyenziswa.Xa ukulinganisa okanye ukulinganisa ireferensi yereferensi efunekayo, ukhetho lwe-flowmeter ebonelela ngomgangatho wokuhamba okusemgangathweni lubaluleke kakhulu.
Iimitha eziphathwayo ze-ultrasonic flow meters ngokubanzi zineesethi ezintathu zeeprobes zokukhetha kuzo, ezi zintathu zeesethi zeprobes, ngokulandelanayo, ezifanelekileyo kwiidamitha zepayipi ezihlukeneyo, iiprobes ezahlukeneyo kunye nomninimzi ngomqondo wokuba ibe yisethi yeemitha ezizimeleyo ezizimeleyo.Kwi-flow calibration, izixhobo zokulinganisa ezinemibhobho eyahlukeneyo kufuneka zisetyenziswe ukulinganisa zonke iidamitha zepayipi ezintathu, kunye needamitha zombhobho wesixhobo sokulinganisa kufuneka zihambelane kunye needamitha zombhobho wokulinganisa.
Indlela yokuqinisekisa echanekileyo isekelwe ekusetyenzisweni komsebenzisi njengesalathiso, kangangoko kunokwenzeka, i-flowmeter ye-ultrasonic ephathekayo ilinganiswe okanye ilinganiswe kwisixhobo somgangatho wokuhamba kunye okufanayo okanye kufuphi nobubanzi bombhobho, kwaye uqinisekise ukuba iqela ngalinye. I-probes yoqwalaselo lwe-flowmeter iyajongwa, kwaye i-calibrating aperture kunye neerekhodi zenombolo yeprobe zirekhodwa kakuhle ukuthintela ukungaqondani.
I-ultrasonic flowmeter ineemfuno ezithile zokusetyenziswa kweemeko kunye nommandla wokusetyenziswa kwendawo, kwaye kufuneka isetyenziswe xa iimeko zidibene.Ukuba indawo yokufakela i-flowmeter ye-ultrasonic ayikwazi ukuhlangabezana neemfuno zobude becandelo lombhobho wangaphambili nangemuva, kuya kuba neempazamo zokulinganisa ngenxa yokungazinzi kwentsimi.Abasebenzisi abaninzi baya kukhawulwa sisixhobo sokulinganisa kakuhle xa usebenzisa, kwaye abanako ukuhlangabezana neemfuno zendawo yokuhlohla, eya kuba neempazamo ezinkulu zokulinganisa.
Ukongezelela, i-clamp yangaphandle ye-ultrasonic flowmeter yendlela yokuhluka kwexesha inomdla ngokukodwa kwiibhubhu ezixutywe kwi-measuring medium, kwaye iibhubhu ziya kubangela ukuba ixabiso lesibonakaliso se-flowmeter lingazinzi.Ukuba igesi eqokelelweyo yenzeke kwindawo yokufakela i-probe, imitha yokuhamba ayiyi kusebenza.Ngoko ke, indawo yokufakela i-clamp yangaphandle-uhlobo lwe-flowmeter ye-ultrasonic kufuneka igwenywe ngokusemandleni ukusuka kwindawo yokupompoza, indawo eqinile yamagnetic kunye nentsimi yombane, kunye nenqanaba eliphezulu lombhobho.
Indawo yofakelo yeprobe ye-flowmeter ye-ultrasonic nayo ifuna ukunqanda umphezulu kunye nomzantsi wombhobho kangangoko kunokwenzeka, kwaye ifakwe phakathi koluhlu lwe-45 ° Angle kunye nobubanzi obuthe tye, kwaye ukufakela kufuneka kuthintele iziphene zemibhobho efana ne-welds. .Ngexesha elifanayo, iimitha zokuhamba ze-ultrasonic azifanelekanga ukufakwa kwindlela yezithuthi ezixineneyo, kwaye uzame ukuphepha ukusebenzisa iifowuni eziphathwayo okanye i-walkie-talkies kufuphi nomninimzi.
Kwinkqubo yokusebenzela abathengi iminyaka emininzi, kukho abathengi abasoloko bephendula inkampani yethu ukuba ukuchaneka kwe-clamp yangaphandle ye-ultrasonic flowmeter ayichanekanga.Enyanisweni, ukuchaneka kokuchaneka kokulinganisa kwemitha yokuhamba nayo kuneengxaki ezibangelwa ngabathengi abasetyenziswayo, njengokungalinganisi ngokuchanekileyo iiparitha zombhobho kuya kuba nefuthe elikhulu ekuchanekeni komlinganiselo.
Ayinakukwazi ukulinganisa ngokuchanekileyo iiparamitha zombhobho okhokelela kwimitha engachanekanga, iprobe ephathekayo ye-ultrasonic flowmeter ifakwe ngaphandle kombhobho, ilinganisa ngokuthe ngqo ukuhamba kolwelo kumbhobho.Eli nqanaba lokuhamba lichaphazeleka kwinqanaba lokuhamba kunye nommandla wokuhamba kombhobho (ububanzi bangaphakathi bombhobho), kwaye idatha yimveliso yabo.Indawo yombhobho kunye nobude besiteshi kubalwa ngeeparitha zepayipi ezifakwe ngumsebenzisi ngesandla.Ukuchaneka kwezi parameters kuya kuchaphazela ngqo iziphumo zokulinganisa.
Kwelinye icala, nokuba imitha yokuqukuqela ngokwayo ayiyongxaki, kodwa ukuba idatha yombhobho wegalelo lomsebenzisi ayichanekanga, iziphumo zomlinganiselo azichanekanga, umlinganiselo weeparamitha zombhobho uya kuba calanye, kunye nobukhulu bodonga lombhobho. iya kutshintsha emva kwexesha lokusetyenziswa, ngoko ke impazamo yedatha yomlinganiselo ayinakuphetshwa.
Ngoko ke, xa silinganisa idatha yobubanzi bombhobho, kufuneka sinikele ingqalelo kwingqiqo yendlela, kunye nezixhobo zokulinganisa kunye nezixhobo kufuneka zilinganiswe.Xa silinganisa le datha, kufuneka sihlawule ngakumbi impembelelo yokhuselo lwangaphandle lombhobho kunye nokugqwala kunye nokungcola kwendawo yangaphandle kwidatha yokulinganisa.
