Intshayelelo
II-Ultrasonic Time-of-Flight Flowmeter efakwe eludongeni eneZiteshi ezibinisisixhobo esichanekileyo kakhulu esisekelwe kwindlela yokwahluka kwexesha lokuhamba nge-ultrasonic (ekwabizwa ngokuba yi-time-of-flight / ToF principle) edibene netekhnoloji ye-dual-channel. Ivumela ukufunyanwa kokuhamba okungalunganga nokuchanekileyo—ilungele ulwelo olucocekileyo.,kwaye isebenza ngobukhulu obahlukeneyo beepayipi kunye nobubanzi bobushushu bolwelo, isebenza ngokuthembekileyo ekujongeni ukuhamba kwamanzi kwimizi-mveliso nakwimizi-mveliso.
UmgaqoyeSixhobo
I-Clamp-On Dual-Channel-Mounted Wall-Mounted Ultrasonic Flowmeteribhekisa kumahluko wexesha xa ii-pulse ze-ultrasonic zisasazeka ngezantsi (ngokuhamba kolwelo) naphezulu (ngokuchasene nokuhamba kolwelo) kwindawo ephakathi. Kulwelo oluzinzileyo, amaxesha okusasazeka kuzo zombini iindlela ayalingana; kulwelo oluhambayo, ii-pulse ezisezantsi "zithwalwa" kukuhamba (ixesha elifutshane) kwaye ii-pulse ezisezantsi zijongene nokumelana (ixesha elide)—lo mahluko uhambelana ngokuthe ngqo nesantya sokuhamba, okwenza umongo wokubala ukuhamba komthamo.
I-Ultrasonic Flowmeter efakwe eludongeni eneChannel ezimbini echanekileyo kakhuluisebenzisa izinzwa zendlela ezimbini ezinee-transducers ezidibeneyo ezibotshelelwe eludongeni lombhobho, ezithumela kwaye zamkele iipulses ngokutshintshana ukuze kukhanyiswe kwicala elihambayo. Iprosesa echanekileyo kakhulu ibala umahluko wexesha (Δt), iyiguqulele kwisantya sokuhamba (v), kwaye idibanise ububanzi bangaphakathi bombhobho (D) kunye nendawo enqamlezileyo (A) ukuze ifumane isantya sokuhamba ngokukhawuleza (Q = v×A). Uyilo lwemijelo emibini luhlawulela ukuphazamiseka kwentsimi yokuhamba komoya kwi-turbulent/laminar flow, nto leyo enciphisa iimpazamo ezingaphakathi.Iindlela zokufakelwa eziqhelekileyo zesensor ziboniswe kumfanekiso, ngendlela ye-V kunye nendlela ye-Z.
Isishwankathelo seeNzuzo
1.Ukuchaneka okuphezulu 0.5%
2.I-Dynamic zero
3.Kulula ukuyifaka, ixabisa kancinci, kwaye ayifuni kunqunyulwa okanye kuphazanyiswe ukucutshungulwa kwemibhobho
4.Uluhlu olubanzi lobushushu bolwelo: -35~200℃
5.Umsebenzi wokufaka idatha
6.Ubuchule bokulinganisa amandla obushushu bunokuba yinto yokuzikhethela
7.Kwizixhobo zombhobho ezisetyenziswa rhoqo kunye nobubanzi ukusuka kwi-20mm ukuya kwi-5m
8.Uluhlu olubanzi lokuhamba kwamanzi oluvela kwicala ngalinye luqala kwi-0.01m/s ukuya kwi-15m/s.
9.Uqwalaselo olusebenziseka lula
Isicelo
Iunikezelo lwamanzi lukamasipala,BI-i-Directional Dual-Channel Dual-Mounted Wall-Mounted Ultrasonic Flowmeterilinganisa ukuhamba kwamanzi kwiipayipi ezingama-20mm-5m ukuze ijonge ukusetyenziswa kunye nokuchonga ukuvuza; ekufudumaleni/efrijini, iTransit Time Flow Meter iyaziqhelanisa ne -35℃-200℃ ukuze ilandelele imidiya yokudlulisa ubushushu, kwaye ngemodyuli yokuzikhethela, ibala amandla obushushu; kumashishini afana nokucubungula iikhemikhali,imitha yokuhamba kwe-ultrasonic ebambekayoyenza kube lula ukulinganisa ukuhamba kweendlela ezimbini (0.01-15m/s) ngaphandle kokuphazamisa imveliso.
Isiphelo
I-Clamp On Ultrasonic Flow Meterifikelela ekuchanekeni kokulinganisa okungu-±0.5%, kunye nokufakelwa kwe-clamp-on okungangeneleliyo okuthintela ukunqunyulwa kwemibhobho kunye nexesha lokungasebenzi. Ihambelana nezixhobo zepayipi eziqhelekileyo, i-Non-Intrusive Flow Measurement igcina ukuthembeka kubushushu obugqithisileyo ngelixa ixhasa ukuloga kwedatha okukrelekrele ukuze kuphuculwe inkqubo. Ujongano oluqondakalayo kunye nokulinganiswa kwe-zero eguquguqukayo (okuhlawula i-transit-time zero drift) kunciphisa ukugcinwa, okwenza kube lolona khetho luphezulu lokulinganisa ukuhamba kwemizi-mveliso kunye nolawulo lwamandla.
