Yeyiphi imiba eya kuchaphazela iziphumo zomlinganiso we-non-contact ultrasonic flowmeters ?

I-Flowmeter ye-Ultrasonic luhlobo lwesixhobo sokulinganisa ulwelo olungaqhagamshelwanga, olusetyenziswa kakhulu kwimizi-mveliso, imimandla yoluntu kunye nokukhuselwa kwendalo.Umgaqo wayo wokusebenza kukusebenzisa umahluko wexesha lokusasazeka kwamaza e-ultrasonic kulwelo ukubala izinga lokuhamba kunye nesantya sokuhamba kolwelo.Nangona kunjalo, kwinkqubo yokusetyenziswa kwangempela, iziphumo zokulinganisa i-flowmeter ye-ultrasonic inokuchaphazeleka yizinto ezahlukeneyo, ezikhokelela kwiimpazamo zokulinganisa.
1. Iimpawu zolwelo
Iipropati zolwelo zinempembelelo ebalulekileyo kwiziphumo zokulinganisa i-flowmeter ye-ultrasonic.Okokuqala, isantya somsindo we-fluid sihambelana nobushushu, uxinzelelo, ugxininiso kunye nezinye izinto, kwaye utshintsho kule miba luya kubangela utshintsho kwisantya somsindo, ngaloo ndlela kuchaphazela iziphumo zokulinganisa.Okwesibini, iimpawu ezibonakalayo ezifana nobuninzi kunye ne-viscosity ye-fluid nayo iya kuchaphazela isantya sokusasaza kunye ne-degree attenuation ye-wave ye-ultrasonic, ngaloo ndlela ichaphazela iziphumo zokulinganisa.Ukongezelela, izinto ezingenayo i-inhomogeneous ezifana ne-bubbles kunye nokungcola kwi-fluid ziya kuphazamisa ukusabalalisa kwamaza e-ultrasonic, okubangelwa iimpazamo zokulinganisa.
2. Ubume bombhobho
Ukwakhiwa kombhobho nako kunempembelelo ethile kwiziphumo zokulinganisa i-flowmeter ye-ultrasonic.Okokuqala, izinto eziphathekayo, ubukhulu bodonga, i-diameter yangaphakathi kunye nezinye iiparitha zombhobho ziya kuchaphazela isantya sokusasaza kunye neqondo lokuthotywa kwamaza e-ultrasonic kumbhobho.Okwesibini, imilo yombhobho, iqondo lokugoba, indlela yokudibanisa, njl., Kuya kuba nefuthe ekusasazeni kwamaza e-ultrasonic.Ukongezelela, ukubola, ukunyuswa kunye nezinye iziganeko ngaphakathi kombhobho kunokutshintsha iimpawu ze-acoustic zombhobho, ngaloo ndlela zichaphazela iziphumo zokulinganisa.
3. Uhlobo lweProbe kunye nendawo yokufakela
Uhlobo lweprobe kunye nendawo yokufakela i-flowmeter ye-ultrasonic inempembelelo ebalulekileyo kwiziphumo zayo zokulinganisa.Iindidi ezahlukeneyo zeprobe zineendlela ezahlukeneyo zokuhambisa kunye nokufumana uvakalelo, ngoko ke ukukhetha uhlobo olufanelekileyo lweprobe kunokuphucula ukuchaneka komlinganiselo.Ukongezelela, indawo yokufakela i-probe kufuneka ibe kude nokungcola, iibhubhu kunye nezinye iziphazamiso kwipayipi njengoko kunokwenzeka ukunciphisa iimpazamo zokulinganisa.Ngexesha elifanayo, ukufakela i-Angle kunye nesalathiso se-probe kuya kuchaphazela ukuhanjiswa kunye nokwamkelwa kwe-wave ye-ultrasonic, efuna ukulungiswa ngokwemeko yangempela.
4. Ingxolo yokusingqongileyo
Umgaqo wokulinganisa we-flowmeter ye-ultrasonic isekelwe kwixesha lokuhluka kwe-ultrasonic wave propagation kumanzi, ngoko ke impembelelo yengxolo yokusingqongileyo kwiziphumo zokulinganisa ayinakuhoywa.Imiqondiso yengxolo efana nokungcangcazela koomatshini kunye nokuphazamiseka kwe-electromagnetic kwimo engqongileyo inokukhutshwa ngemiqondiso ye-ultrasonic, ekhokelela kwiimpazamo zokulinganisa.Ukuze kuncitshiswe impembelelo yengxolo yokusingqongileyo, amanyathelo afana ne-sound insulation kunye nokukhusela angathathwa, okanye i-flowmeter ye-ultrasonic ene-signal-to-noise ratio inokukhethwa.
5. Ukusebenza kwesixhobo kunye nolungelelwaniso
Ukusebenza kunye nokulinganisa imeko ye-flowmeter ye-ultrasonic inempembelelo ngqo kwiziphumo zayo zokulinganisa.Okokuqala, amandla okuhambisa isixhobo, ukufumana uvakalelo, amandla okusebenza komqondiso kunye nezinye iiparamitha zokusebenza kufuneka zihlangabezane neemfuno zokulinganisa ukuqinisekisa ukuchaneka komlinganiselo.Okwesibini, isixhobo kufuneka silinganiswe kwaye sigcinwe rhoqo ukuphelisa iimpazamo ezinje nge-zero drift kunye ne-fain drift.Ukongezelela, i-algorithm yesofthiwe kunye nekhono lokucubungula idatha yesixhobo nayo iya kuchaphazela ukuchaneka kweziphumo zokulinganisa.
Iziphumo zokulinganisa ii-flowmeters ze-ultrasonic zichatshazelwa yizinto ezininzi, kubandakanywa ubunjani be-fluid, isakhiwo sombhobho, uhlobo lwe-probe kunye nendawo yokufakela, ingxolo ye-ambient, kunye nokusebenza kwesixhobo kunye nokulinganisa.Ukuze kuphuculwe ukuchaneka komlinganiselo kunye nokuthembeka kwee-flowmeters ze-ultrasonic, ezi zinto zichaphazelayo kufuneka ziqwalaselwe ngokupheleleyo kwaye zilawulwe.
