I-flowmeter ye-ultrasonic ephathekayo luhlobo lwe-flowmeter ye-ultrasonic.I-Ultrasonic flowmeter yi-flowmeter esebenza kwi-ultrasonic time difference kunye ne-Doppler mode, kuba ukuchaneka kokulinganisa ukuchaneka kwe-flowmeter ye-ultrasonic iphantse izimele kwiqondo lokushisa kunye noxinzelelo lokuhamba okulinganiswayo.I-Viscosity, ingxinano kunye nezinye iiparameters, kwaye inokwenziwa kwisixhobo sokulinganisa esingaqhagamshelwanga kunye nesiphathwayo, ngoko ke inokusombulula ezinye iingxaki zokulinganisa umlinganiselo wokuhamba ezifana ne-corrosive eyomeleleyo, i-non-conductive, i-radioactive kunye neendaba ezinokutsha kunye neziqhushumbisi.Iindidi zezixhobo.Ukusebenza kwayo okwahlukileyo kuye kwaphumelela ukuthandwa ngabasebenzisi.
1. Impembelelo yendawo yokufakela, i-coupler kunye nomgca wesignali kumlinganiselo
Ii-flowmeters ze-ultrasonic eziphathwayo ubukhulu becala zisebenzisa i-multi-pulse, imiqondiso yebroadband, enekhono elithile lokumelana nokuphazamiseka kombane.Nangona kunjalo, kukho iifrikhwensi eziphezulu kwindawo yofakelo, ngakumbi ukuba umthombo wophazamiseko loguqulelo awusebenzi ngokupheleleyo.Umgca wesignali we-transducer akulula ukuba ube mde kakhulu, kwaye intambo ye-coaxial ye-impedance ethile kufuneka isetyenziswe, kwaye akufanele kubekho ukudibanisa ekupheleni naphakathi.I-agent ye-ultrasonic coupling kufuneka isetyenziswe ngokusemandleni kunye ne-conductivity yesandi esilungileyo kwaye akulula ukuxuba izinto ze-gas viscous, ezifana neglasi yamanzi, i-Vaseline, njl.
I-2, i-flowmeter ye-ultrasonic ayilinganisi ngokuchanekileyo
Nayiphi na i-flowmeter kufuneka iqinisekiswe okanye ilinganiswe ngaphambi kokusetyenziswa, kwaye ii-flowmeters eziphathekayo ze-ultrasonic zibaluleke kakhulu ngeli xesha.Ngenxa yokuba imitha yokuhamba ye-ultrasonic ephathekayo ngokuqhelekileyo ixhotyiswe ngeeseti ezininzi zee-transducers, ezifanelekileyo kwiindidi zemibhobho yobubanzi obuhlukeneyo, isethi nganye ye-transducer kunye nendibaniselwano yomninimzi ithiyori isethi yeemitha zokuhamba.Ngoko ke, ukuba kuphela i-transducer encinci isetyenziselwa ukulinganisa okanye ukulinganisa i-flowmeter ye-ultrasonic ephathekayo kwisixhobo somgangatho wokuhamba kunye nobubanzi bombhobho omncinci, ngoko ukuba i-transducer enkulu isetyenziselwa ukulinganisa ukuhamba ngexesha lokusetyenziswa, ilingana nokusebenzisa i-unverified okanye i-transducer enkulu. I-flowmeter calibrated ngokuchaneka komlinganiselo ongenakuqinisekiswa.Indlela echanekileyo isekelwe kusetyenziso lomsebenzisi ngokwakhe njengereferensi, kwaye i-flowmeter ye-ultrasonic ephathekayo kufuneka ihlolwe okanye ilinganiswe kwiipayipi ezininzi kwizixhobo ezisemgangathweni ezinomlinganiselo ofanayo okanye kufuphi nombhobho osetyenzisiweyo.Ubuncinci, kuyimfuneko ukuqinisekisa ukuba isethi nganye yeenzwa ezilungiselelwe kunye nemitha yokuhamba kufuneka ilinganiswe.Isiqinisekiso semitha okanye isatifikethi solungelelwaniso siya kunika umba wolungiso lweemitha kwiiseti ezininzi zabenzi boluvo.Xa usebenzisa ixesha lokuhamba, qiniseka ukuba ufaka into echanekileyo yokulungiswa kweemitha kwisidlulisi esihambelanayo.
I-3, iintsilelo ze-flowmeter ephathekayo ye-ultrasonic kunye nokulinganiselwa
(1) I-flowmeter ye-ultrasonic ephathekayo yendlela yokuhamba kwexesha ingasetyenziselwa kuphela ukucoca ulwelo kunye neegesi.
(2) Imibhobho yombane eneziguquli zangaphandle ayinakusetyenziselwa imibhobho enemigca engqindilili okanye yokukalwa, imibhobho ebotshwe ekuhlaleni okanye ephakanyisiweyo, kunye nemibhobho enomhlwa kakhulu weendonga zemibhobho.
(3) Imveliso yangoku yasekhaya yee-flowmeters ze-ultrasonic ezikhoyo azikwazi ukusetyenziselwa imibhobho enobubanzi obungaphantsi kwe-DN25mm.
(4) Uphuhliso kunye nokuveliswa kwee-flowmeters ze-ultrasonic zasekhaya kusekutsha, kwaye ixabiso liphezulu.
Ukulinganisa okuhambayo kuyipharamitha ebalulekileyo kwinkqubo yokuvelisa amashishini, ngokukodwa kwintsimi yokugcinwa kwamandla kunye nokugcinwa kwamanzi kunye nokunye ukukhuselwa kwendalo kuye kwasetyenziswa ngakumbi.I-Flowmeter ye-ultrasonic ephathekayo luhlobo olutsha lwe-flowmeter, ukulungeleka kwayo kunye noqoqosho lwezinye ii-flowmeters azikwazi bini.Nangona kunjalo, iimpazamo ezininzi ezingaqhelekanga ezenziwe zizixhobo ezinjalo zifuna ukufundisisa okuqhubekayo kunye nengxoxo.Ngokomzekelo, utshintsho kwindawo yentsimi, ukuphindaphinda kwamandla, ukulinganisa kwindonga yangaphakathi yombhobho, kunye neebhubhu kumbhobho kuya kubangela utshintsho oluthile kwixabiso lephutha lokulinganisa.Ngoko ke, rhoqo ushwankathela iindlela zokulinganisa ezichanekileyo ukusuka ekusebenzeni, ngumsebenzi wexesha elide wokusebenzisa kakuhle i-flowmeters ephathekayo ye-ultrasonic ukudlala indima yayo esebenzayo.
I-Flowmeter ye-ultrasonic ephathekayo ineempawu zokufakela ngokukhawuleza kunye nokusetyenziswa okuguquguqukayo, kodwa kufuneka ilawule indlela echanekileyo xa usebenzisa.Emva kweminyaka yamava okusebenza kwintsimi, kufunyenwe ukuba ukusetyenziswa kwee-flowmeters eziphathekayo ze-ultrasonic kulula ukungahoywa, ukuhlalutya izizathu zeengxaki kunye nokuphakamisa izisombululo.
