Njengeyunithi yokulawula engundoqo, uyilo kunye nomsebenzi weI-vortex flowmeteribhodi yesekethe ichaphazela ngokuthe ngqo ukusebenza kwe-flowmeter. Ngokusekwe kumgaqo-nkqubo wokusebenza kwe-vortex flowmeter (ukubona ukuhamba kwamanzi okusekwe kwi-Karman vortex phenomenon), iingenelo eziphambili zebhodi yesekethe yayo inokushwankathelwa ngolu hlobo lulandelayo kwiinkalo zeempawu zobugcisa, iinzuzo zokusebenza, kunye nexabiso lesicelo:
Ukufunyanwa ngokuchanekileyo kweempawu zefrikhwensi ephezulu:
Ibhodi yesekethe idibanisa iimodyuli ze-analog-to-digital conversion (ADC) kunye ne-digital signal processing (DSP) chips, ezinokuthi zibambe iimpawu ze-frequency ezibuthathaka (ngokuqhelekileyo amashumi ukuya kumawaka e-Hz) eveliswa yi-vortex generators ngexesha langempela. Ngokucofa, ukukhulisa, kunye ne-algorithms yokunciphisa ingxolo, impazamo yokufumana umqondiso iqinisekiswa ukuba ingaphantsi kwe-0.1%, ihlangabezana neemfuno zokulinganisa ngokuchanekileyo (njengokuchaneka komlinganiselo we-± 1% R).
Imbuyekezo engahambelaniyo kunye ne-algorithms yobukrelekrele:
I-microprocessor eyakhelwe ngaphakathi (MCU) inokulungisa impembelelo yobuninzi be-fluid kunye ne-viscosity utshintsho kwiziphumo zokulinganisa ngokusebenzisa i-algorithms yembuyekezo yeqondo lokushisa / uxinzelelo, ukulungelelanisa kwiimeko ezahlukeneyo zokusebenza (ezifana nokushisa okuphezulu, uxinzelelo oluphezulu, kunye ne-variable medium), kunye nokuphucula ukuzinza komlinganiselo kwiindawo ezinzima.
Ukuthembeka okuphezulu kunye noyilo oluchasene nokuphazamiseka
Ukomelezwa kwe-Hardware anti-interference:
Ukwamkela i-PCB ene-multi-layer layout, i-electromagnetic shielding (efana ne-metal shielding cover), ukuhluza amandla (i-LC filtering circuit, imodyuli yamandla eyedwa) kunye neteknoloji yokuhlukanisa i-optocoupler (i-optocoupler isolation, ukuhanjiswa kwesignali eyahlukileyo), iyaxhathisa ngokufanelekileyo ukuphazamiseka kwe-electromagnetic interference (EMI), ukuphazamiseka kwamaza kanomathotholo (RFI) kunye nengxolo yamandla kwiindawo eziguquguqukayo ezifana nokuphazamiseka kwemoto kunye nokuphazamiseka okunamandla.
Ubushushu obubanzi kunye nokuguquguquka koxinzelelo olubanzi:
Khetha amacandelo ombane odidi lwemizi-mveliso (afana nobushushu be-ambient: -30 ° C ukuya + 65C; ukufuma okuhambelanayo: 5% ukuya kuma-95%; uxinzelelo lwe-Atmospheric: 86KPa ~ 106KPa, imodyuli yegalelo lombane obanzi), ixhasa i-DC 12 ~ 24V okanye i-AC 220V igalelo lamandla, ilungele imeko-bume erhabaxa, i-vibration yangaphandle kunye ne-vib.
Ibhodi yesekethe yeI-vortex flowmeterifezekisa ukuchaneka, ukuzinza, kunye nokuguquguquka kumlinganiselo wokuhamba ngeenzuzo ezifana nokulungiswa kwesignali ephezulu ngokuchanekileyo, ukukwazi ukuchasana nokuphazamiseka, ukudibanisa okusebenzayo okuhlakaniphile, kunye noyilo lwamandla aphantsi. Isetyenziswa ngokubanzi kumashishini afana neepetrochemicals, amandla, amanzi, i-metallurgy, njl., ngakumbi kwiimeko ezinzima zokusebenza kunye neenkqubo ezizenzekelayo. Ixabiso layo eliphambili lilele ekuphuculeni ngokubambisana kwesoftware kunye ne-hardware ukuphucula ukusebenza kwesixhobo ngelixa kuncitshiswa ukusetyenziswa komsebenzisi kunye neendleko zokugcina.
