Umgomo oyinhloko wokusebenza we-Coriolis Mass Flow Meter (ebizwa ngokuthi i-Coriolis flow meter ngamafuphi) ukusebenzisa amandla e-Coriolis akhiqizwa lapho uketshezi lugeleza ngaphakathi kwepayipi elidlidlizayo, bese ulinganisa ngqo izinga lokugeleza kobuningi boketshezi ngokuthola umehluko wesigaba sepayipi elidlidlizayo. Ingathola futhi futhi ilinganise amapharamitha anjengobuningi kanye nokushisa.
Ukuhlukaniswa Kwezimiso Eziyinhloko
Ukukhiqizwa Kwamandla eCoriolis Amandla eCoriolis angamandla angenawo amandla. Uma into ihamba ngomugqa ohlakeni lokubhekisela olujikelezayo, ifakwa emandleni aqonde kokubili ohlangothini lokunyakaza kanye ne-axis yokujikeleza. Kumitha yokugeleza kweCoriolis, ishubhu yokulinganisa edlidlizayo isebenza "njengohlaka lokubhekisela olujikelezayo", kanti uketshezi olugeleza ngaphakathi kweshubhu lusebenza "njengento ehambayo".
I-Vibration Drive ye-Measuring TubeI-tube yokulinganisa ye-flow meter (ngokuvamile enomumo ongu-U, eqondile, noma egobile kabili) iqhutshwa yi-actuator nge-frequency ehleliwe (i-natural frequency) ukuze yenze i-reciprocating vibration ngezikhathi ezithile (efana ne-vibration ye-tuning fork). Uma kungekho ukugeleza koketshezi ngaphakathi kwe-tube, i-vibration ye-measuring tube iyalingana, futhi izigaba ze-vibration emaphethelweni okungena kanye ne-outlet ye-tube zihambisana ngokuphelele.
Umehluko Wesigaba Obangelwa Ukugeleza Koketshezi Lapho uketshezi lugeleza lusuka ekugcineni kokungena luye ekugcineni kokuphuma ngaphakathi kwepayipi elidlidlizayo:
Uma uketshezi ludlidliza phezulu ngepayipi lokulinganisa, lufakwa amandla eCoriolis avimbela ukudlidliza, okuholela ekubambezelekeni kwesigaba ekugcineni kokungena kwepayipi.
Uma uketshezi ludlidliza phansi ngethubhu yokulinganisa, lufakwa amandla eCoriolis akhuthaza ukudlidliza, okuholela ekuqhubekeni kwesigaba ekugcineni kokuphuma kwethubhu.
Lo mehluko ngamandla ubangela umehluko wesigaba phakathi kokuphela kokungena nokukhipha kwepayipi lokulinganisa, futhi ubukhulu bomehluko wesigaba buhambisana ngqo nesilinganiso sokugeleza kobuningi boketshezi.
Izinzwa Zokuthola Izimpawu Nokubala (njengezinzwa ze-electromagnetic) zifakiwe kuzo zombili iziphetho zethubhu yokulinganisa ukuthola izimpawu zesigaba sokudlidliza. Umthumeli wemitha yokugeleza uguqula isignali yomehluko wesigaba ibe isignali kagesi, bese ubala izinga lokugeleza kobuningi boketshezi nge-algorithm eyakhelwe ngaphakathi (ukulinganisa okuqondile ngaphandle kwesidingo sokunciphisa izinga lokushisa kanye nengcindezi). Okwamanje, imvamisa yemvelo yethubhu yokulinganisa ihlobene nobuningi boketshezi ngaphakathi kwethubhu, ngakho-ke ubuningi boketshezi bungabalwa futhi ngemvamisa yokudlidliza.
Izici Eziyinhloko (Kuhlanganiswe namapharamitha Obuchwepheshe be-Flow Meter)
Ukulinganisa okuqondile kwesilinganiso sokugeleza kwesisindo: Ngokungafani namamitha okugeleza evolumu (njenge-vortex kanye namamitha okugeleza kagesi), asikho isidingo sokuguqulwa ngobuningi, ngakho-ke ukunemba kanye nokuphindaphinda akuthinteki kakhulu yizimo zokusebenza.
Ukusebenza kabanzi kwimidiya: Ingalinganisa uketshezi, amagesi, kanye nokugeleza kwezigaba eziningi (njengoketshezi oluqukethe amabhamuza kanye nama-slurries), futhi ifaneleka kakhulu kwimidiya ene-viscosity ephezulu, izinga lokushisa eliphezulu, kanye nengcindezi ephezulu.
Izinzuzo kumapharamitha obuchwepheshe: Ukunemba ngokuvamile kungafinyelela ku-±0.1%～±0.5%, futhi ukuphindaphindeka kungafinyelela ku-±0.02%～±0.1%, okuhambisana nezindinganiso zomhlaba wonke ezifana ne-ISO 9104 kanye ne-ASTM D5125.
