Amamitha okugeleza ahlukahlukene asebenza ekuthuthukiseni ukusebenza kahle kwesistimu, ukunemba kanye nokuthembeka kwayo okuhlala isikhathi eside. Kubalulekile ukubheka izici ezincane zohlobo ngalunye nokuthi zixazulula kanjani izidingo ezibalulekile zezimboni. Thola uhlobo lwemitha yokugeleza ukuze ihlangabezane nezidingo ezithile.
Izinhlobo Zamamitha Okugeleza
Imitha yokugeleza kwesisindo
Aimitha yokugeleza kwesisindo, eyaziwa nangokuthi i-inertial flow meter, isetshenziselwa ukukala izinga lokugeleza kobuningi boketshezi olugeleza ngepayipi. Isisindo soketshezi olugeleza sidlula iphuzu eliqondile ngesikhathi seyunithi ngayinye sibizwa ngokuthi izinga lokugeleza kobuningi. I-mass flow meter ikala isisindo kunokuba ivolumu ngesikhathi seyunithi ngayinye (isb. kgs ngomzuzwana) ethumela ngedivayisi.
Amamitha okugeleza eCorioliszithathwa njengezilinganiso zokugeleza ezinembe kakhulu ezingaphindeka njengamanje. Zithumela uketshezi kumashubhu adlidlizayo futhi ziqaphe izinguquko emgudwini woketshezi. Uketshezi oludlula kumashubhu adlidlizayo lubangela ukujiya noma ukuwohloka okuncane. Ukujiya okunjalo nokuguquguquka kuhambisana ngqo namazinga okugeleza kobuningi. Amamitha e-Coriolis asebenza kokubiliukulinganisa ubukhulu kanye nobuningi, ekwazi ukusebenzisa izindlela ezahlukene ekusetshenzisweni okuhlukahlukene njengamakhemikhali, izimboni zikawoyela negesi. Ukusebenza kwazo okuvelele ngokunemba nokusetshenziswa kabanzi yizona zizathu eziyinhloko zokuthandwa kwazo ezinhlelweni zezimboni eziyinkimbinkimbi.
Uhlobo Lokuvimbela
Amamitha okugeleza okucindezela okuhlukile (DP)ziye zahlungwa ukuze zithuthukiswe ezidingweni zezimboni zanamuhla, okuhlala kuyindlela ethembeke kakhulu ekuqapheni nasekulinganisweni kokugeleza. Umehluko wokucindezela ulinganiswa ngesisekelo sesimiso sokuthi ubuhlobo obuthile phakathi komehluko wokucindezela okhiqizwayo lapho uketshezi lugeleza kumadivayisi okugoqa kanye namazinga okugeleza. Idivayisi yokugoqa iyinto yokugoqa yendawo efakwe epayipini. Esetshenziswa kakhulu yileziamapuleti odonga, ama-nozzlefuthiamashubhu e-venturi,isetshenziswa kabanzi ekulinganisweni nasekulawuleni izinqubo zezimboni.
A imitha yendawo eguquguqukayoisebenza ngokulinganisa ukugeleza koketshezi okuwela indawo yesigaba sedivayisi ukuze kuhlukahluke ngokuphendula ukugeleza. Umphumela othile olinganisekayo ukhombisa izinga. I-rotameter, isibonelo semitha yendawo eguquguqukayo, iyatholakala ezinhlotsheni eziningi zoketshezi futhi ivame ukusetshenziswa ngamanzi noma emoyeni. Esinye isibonelo i-orifice yendawo eguquguqukayo, lapho ukugeleza koketshezi okuthumela nge-orifice kuzophambukisa i-plunger efakwe entwasahlobo.
I-Inferential Flowmeter
Ii-turbine flowmeteriguqula isenzo somshini sibe yisilinganiso sokugeleza esingafundeka kalula. njenge-gpm, i-lpm, njll. Isondo le-turbine libekwe endleleni yomfula ogelezayo ukuze konke ukugeleza okuhambayo kuzungeze lona. Bese uketshezi olugelezayo luthinta ama-blade e-turbine, lukhiqize amandla e-blade futhi lusunduze i-rotor inyakaze. Ijubane le-turbine lilingana nejubane loketshezi lapho isivinini sokujikeleza esizinzile sifika.
I-Electromagnetic Flowmeter
Ii-flowmeter yamagnetic, obeye aziwe njengo "imitha ye-mag"noma"i-electromag", sebenzisa insimu ye-megnetic efakwe kushubhu lokulinganisa, okubangela umehluko ongaba khona ekulinganisweni kwejubane lokugeleza eliqondile emigqeni ye-flux. Amamitha anjalo asebenza kuMthetho kaFaraday we-Electromagnetic Induction, lapho insimu yamagnetic isetshenziswa khona kuketshezi. Khona-ke izinga lokugeleza linganqunywa yi-voltage elinganisiwe ephumayo. Isixazululo esisetshenziswayo sezimboni ezibandakanya uketshezi olungcolile, olubolayo noma oluqothulayo. Ngezinjongo zokunemba nokuqina,amamitha okugeleza kazibuthezivame ukusetshenziswa ekuhlanzweni kwamanzi, ekucutshungulweni kwamakhemikhali, kanye nasekukhiqizweni kokudla neziphuzo.
I-Animitha yokugeleza kwe-ultrasonicIlinganisa ijubane loketshezi nge-ultrasound ukuze ibale ukugeleza kwevolumu. Imitha yokugeleza iyakwazi ukukala ijubane elimaphakathi endleleni yomsebe okhishwayo we-ultrasound nge-transduces ye-ultrasonic. Bala umehluko wesikhathi sokudlulisa phakathi kwama-pulse e-ultrasound angene noma aphikisane nesiqondiso sokugeleza noma ulinganise ukushintsha kwemvamisa kuye nge-Doppler Effect. Ngaphezu kwempahla ye-acoustic yoketshezi, izinga lokushisa, ubuningi, i-viscosity kanye nezinhlayiya ezimisiwe nazo ziyizici ezithinta i-imitha yokugeleza kwe-ultra.
Aimitha yokugeleza kwe-vortexisebenza ngesimiso esithi "von Kármán vortex", iqapha izinga lokugeleza koketshezi ngokulinganisa imvamisa yama-vortices. Ngokuvamile, imvamisa yama-vortices ilingana ngqo nezinga lokugeleza. Isici se-piezoelectric esise-detector sikhiqiza isignali yokushaja eshintshanayo enemvamisa efanayo ne-vortex. Ngemuva kwalokho isignali enjalo ilethwa ku-intelligent flow totalizer ukuze icutshungulwe kabanzi.
Ama-flowmeter omshini
Imitha yokuhambisa eqondile ilinganisa umthamo woketshezi olugeleza esitsheni njengebhakede noma iwashi lokumisa. Izinga lokugeleza lingabalwa ngesilinganiso somthamo nesikhathi. Ukugcwalisa nokuthulula amabhakede ngokuqhubekayo kuyadingeka ngenhloso yokulinganisa okuqhubekayo. Amamitha e-piston, amamitha egiya eliyindilinga kanye nemitha yediski yokunatha konke kuyizibonelo zamamitha okuhambisa eqondile.
Kusukela kuma-flowmeter omshini aguquguqukayo kuya kuma-Coriolis anembile kakhulu kanye namamitha e-ultrasonic, uhlobo ngalunye lwenzelwe ukuhlangabezana nezidingo ezithile zezimboni. Kungakhathaliseki ukuthi udinga ukuphatha amagesi, uketshezi, noma umusi, kukhona ikhambi lakho. Thatha isinyathelo esilandelayo sokuthuthukisa ukusebenza kahle kohlelo lwakho ngokufinyelela isiqondiso sochwepheshe.Xhumana nathinamuhla ukuze uthole isilinganiso samahhala, esingenasibopho, futhi ake sikusize uthole imitha yokugeleza efanele umsebenzi wakho!
