Amamitha okugeleza ahlukahlukene asebenza ekuthuthukiseni ukusebenza kahle kohlelo, ukunemba ngisho nokwethembeka okuhlala isikhathi eside. Kubalulekile ukubheka ama-nuances ohlobo ngalunye nokuthi azixazulula kanjani izidingo ezibalulekile zezimboni. Thola uhlobo lwemitha yokugeleza ukuze uhlangabezane nezidingo ezithile.
Izinhlobo zama-Flow Meters
Imitha yokugeleza okukhulu
Aimitha yokugeleza okukhulu, okubizwa ngokuthi i-inertial flow meter, isetshenziselwa ukukala izinga lokugeleza kwenqwaba yoketshezi olugeleza ngeshubhu. Isisindo soketshezi olugeleza sidlule endaweni engashintshi ngesikhathi seyunithi sibizwa ngesilinganiso sokugeleza okukhulu. Imitha yokugeleza kwesisindo ikala isisindo kunevolumu ngesikhathi seyunithi (isb. kgs ngomzuzwana) ukuthumela ngocingo.
Amamitha okugeleza kwe-Coriolisathathwa njengamamitha okugeleza anembe kakhulu aphindaphindwayo njengamanje. Bathumela uketshezi kumashubhu adlidlizayo futhi baqaphe izinguquko kumfutho woketshezi. Uketshezi ngamashubhu adlidlizayo kubangela ukusonteka noma ukonakala. Ukusonteka okunjalo kanye nokukhubazeka kuhambisana ngokuqondile namazinga okugeleza okukhulu. Amamitha e-Coriolis enza kuzo zombiliisilinganiso sobuningi nokuminyana, eguquguquka emisebenzini ehlukahlukene njengezimboni zamakhemikhali, zikawoyela, negesi. Ukusebenza kwabo okuvelele ngokunemba nokusetshenziswa okusabalele kuyizizathu eziyinhloko zokuthandwa kwabo ezinhlelweni zezimboni eziyinkimbinkimbi.
Uhlobo Lokuvimba
Differential Pressure (DP) flow metresacwengisisiwe ukuze athuthuke ezidingweni zemboni yesimanje, ahlala eyindlela ethembeke kakhulu ekuqapheni nokukalwa kokugeleza. Umehluko wengcindezi ulinganiswa ngesisekelo somgomo wokuthi ubudlelwano obuthile phakathi komehluko wengcindezi okhiqizwa lapho uketshezi lugeleza kumadivayisi adonsayo kanye namazinga okugeleza. Idivayisi edonsayo iyisici sokufinyezwa sasendaweni esifakwe epayipini. Ezisetshenziswa kakhulu yileziamapuleti e-orifice, imibhobhofuthiamashubhu e-venturi,isetshenziswa kabanzi ekukaleni nasekulawuleni inqubo yezimboni.
A imitha yendawo eguquguqukayoisebenza ngokulinganisa ukugeleza koketshezi olunqamula indawo yengxenye yocingo ukuze ihluke ekuphenduleni ukugeleza. Omunye umphumela olinganisekayo ukhombisa izinga. I-rotameter, isibonelo semitha yendawo eguquguqukayo, iyatholakala kuhlu olubanzi loketshezi futhi ivame ukusetshenziswa ngamanzi noma emoyeni. Esinye isibonelo i-orifice yendawo eguquguqukayo, lapho ukugeleza koketshezi oluthumela ku-orifice kuzophambukisa i-plunger ene-tapered egcwele intwasahlobo.
I-Flowmeter ye-Inferential
II-flowmeter ye-turbineiguqula isenzo sokusebenza sibe izinga lokugeleza elifundeka umsebenzisi. njenge-gpm, i-lpm, njll. Isondo le-turbine lisethwe endleleni yoketshezi olugelezayo ukuze konke ukugeleza okulizungezile. Khona-ke uketshezi olugelezayo lugxambukela ezinsizeni zophephela, kukhiqize amandla ku-blade futhi luphushe i-rotor inyakaze. Isivinini se-turbine silingana nesivinini soketshezi lapho isivinini sokuzungeza esizinzile sifinyelela.
I-Electromagnetic Flowmeter
II-flowmeter magnetic, obeye aziwe njengo "imitha enkulu"noma"i-electromag", sebenzisa inkambu ye-megnetic esetshenziswe kushubhu lemitha, okubangela umehluko ongaba khona esilinganisweni sokugeleza kwesivinini ngokuqondana nemigqa egelezayo. Amamitha anjalo asebenza kuMthetho kaFaraday Wokungeniswa kuka-Electromagnetic, lapho kusetshenziswa inkambu kazibuthe oketshezini. Bese izinga lokugeleza linganqunywa amandla kagesi alinganisiwe ukunemba nokuqina,amamitha okugeleza kazibuthezivame ukusetshenziswa ekuhlanzeni amanzi, ukucubungula amakhemikhali, kanye nokukhiqiza ukudla neziphuzo.
Animitha yokugeleza ye-ultrasonicikala isivinini soketshezi nge-ultrasound ukubala ukugeleza kwevolumu. Imitha yokugeleza iyakwazi ukukala isivinini esimaphakathi endleleni yomugqa okhishiwe we-ultrasound ngokusebenzisa ama-ultrasonic transduces. Bala umehluko wesikhathi sokuthutha phakathi kwama-pulses e-ultrasound phansi ukuya noma ngokumelene nendawo yokugeleza noma ulinganise ukushintshwa kwemvamisa uncike ku-Doppler Effect. Ngaphezu kwesakhiwo se-acoustic soketshezi, izinga lokushisa, ukuminyana, i-viscosity kanye nezinhlayiya ezimisiwe nakho kuyizici ezinomthelelaultra flow meter.
Ai-vortex flow meterisebenza ngesimiso esithi "von Kármán vortex", iqapha izinga lokugeleza koketshezi ngokulinganisa imvamisa yama-vortices. Ngokuvamile, imvamisa ye-vortices ilingana ngokuqondile nezinga lokugeleza. Isici se-piezoelectric kumtshina sikhiqiza isignali yokushaja eshintshanayo enefrikhwensi efanayo neye-vortex. Bese isignali enjalo ilethwa kuthothaliza yokugeleza ehlakaniphile ukuze kuqhutshekwe nokucubungula.
Ama-flowmeters wemishini
Imitha yokugudluza evumayo ikala umthamo woketshezi olugeleza emkhunjini njengebhakede noma isitophuwashi. Izinga lokugeleza lingabalwa ngesilinganiso sevolumu nesikhathi. Ukugcwalisa nokuthulula amabhakede ngokuqhubekayo kuyadingeka ngenjongo yokulinganisa okuqhubekayo. Amamitha we-piston, amamitha wegiya eliqandayo kanye nemitha yediski enomsoco zonke ziyizibonelo zamamitha amahle okufuduka.
Kusukela kuma-flowmeters emishini ahlukahlukene kuya ku-Coriolis enembile kakhulu namamitha we-ultrasonic, uhlobo ngalunye lwenzelwe ukuhlangabezana nezidingo ezithile zezimboni. Noma ngabe udinga ukuphatha amagesi, uketshezi, noma isitimu, kunesixazululo sakho. Thatha isinyathelo esilandelayo sokuthuthukisa ukusebenza kahle kwesistimu yakho ngokuzama ukuthola isiqondiso sochwepheshe.Xhumana nathinamuhla ngesaphulelo samahhala, esingaphoqelekile, futhi sikuvumele sikusize uthole imitha yokugeleza ephelele yokusebenza kwakho!
