Taolong ea lits'ebetso tsa indasteri, lipatlisisong tsa mahlale le khoebong, tekanyo e nepahetseng ea phallo ea mokelikeli ke ea bohlokoa. Ho fapana le limithara tsa phallo ea mokelikeli—tseo lipalo tsa tsona li sothoang habonolo ke liphetoho tsa mocheso le khatello—limithara tsa phallo ea boima (MFMs) li lekanya boima ba mokelikeli o fetang ka har'a phaephe ka kotloloho kapa ka tsela e sa tobang, ho netefatsa ho nepahala ho tsitsitseng ho sa tsotelehe maemo a tikoloho.

Bophahamo ba mokelikeli ke phetoho e itshetlehileng hodima mocheso le kgatello; mohlala, kgase e atoloha tlasa dithempereichara tse phahameng, e leng se lebisang ditekanyong tse sa nepahalang tse thehilweng hodima bophahamo. Ka lehlakoreng le leng, boima ba mokelikeli bo dula bo tsitsitse, e leng se etsang hore e be paramethara e loketseng bakeng sa ho lekola phallo e nepahetseng. Dimithara tsa phallo ya mokelikeli tsa setso di hloka ditokiso tse eketsehileng bakeng sa bongata, mocheso le kgatello, tse hlahisang dintlha tse ngata tsa diphoso. Dimithara tsa phallo ya boima di fedisa bothata bona ka ho shebana le boima ka ho toba, ebang ke ka ditlamorao tsa mmele (mohlala, matla a Coriolis) kapa dipalo tse nkiloeng (ho kopanya data ya phallo ya mokelikeli le bongata).
Mefuta ea Bohlokoa ea Methapo ea Phallo ea Boima
Methara ea phallo ea boima e arotsoe ka mefuta e tobileng (ho lekanya phallo ea boima ka kotloloho) le mefuta e sa tobang (ho bala phallo ea boima ho tsoa liparamenteng tse ling), e 'ngoe le e 'ngoe e na le matla a ikhethang bakeng sa lits'ebetso tse itseng.
1. Methara ea Phallo ea Boima ea Mofuta o Otlolohileng
- Limithara tsa Phallo ea Bongata ba Coriolis (CMFMs): Tekanyetso ea khauta bakeng sa ho nepahala ho hoholo, li-CMFM li sebelisa phello ea Coriolis—e ileng ea fumanoa ka lekhetlo la pele ka 1832—ho lekanya phallo ea boima. CMFM e tloaelehileng e na le lipeipi tse peli tse thothomelang tse bapileng (hangata tse bōpehileng joaloka U kapa tse otlolohileng) tse tsamaisoang ke khoele ea motlakase. Ha mokelikeli o phalla ka har'a lipeipi, o hlahisa matla a sothang a lekanang le phallo ea oona ea boima, o etsa phapang ea mohato lipakeng tsa li-sensor lipheletsong tsa tube. Phapang ena ea mohato e fetolela ka ho toba phallo ea boima. Li-CMFM li boetse li lekanya bongata ba mokelikeli (ka maqhubu a ho thothomela ha tube) le mocheso (ka li-sensor tse hahiloeng kahare), tse etsang hore li be le mekhoa e mengata bakeng sa lino, likhase le slurry. Ho nepahala ha tsona (± 0.1% ho isa ho ± 0.5%) le litlhoko tse fokolang tsa lipeipi tse otlolohileng li lumellana le maemo a bohlokoa joalo ka khoebo ea oli le tekanyo ea meriana.
- Methapo ea Phallo ea Boima ba Thermal (TMFMs): E loketse ho lekanya khase, li-TMFM li sebelisa melao-motheo ea phetisetso ea mocheso. Sensor e futhumetseng le sensor ea litšupiso li hlahloba liphapang tsa mocheso: ha metsi a phalla, e pholisa sensor e futhumetseng, 'me matla a hlokahalang ho boloka mocheso o sa fetoheng (kapa ho theoha ha mocheso ka bohona) a amana le phallo ea boima. Li ipabola ka sekhahla se tlase sa phallo (mohlala, likhase tsa ts'ebetso ea semiconductor) 'me li fana ka karolelano e pharaletseng ea ho theoha (ho fihlela ho 100:1). Leha ho le joalo, ha li tšoanelehe haholo bakeng sa lino tse nang le viscosity e phahameng kapa likhase tse nang le metsoako e fapaneng, kaha phetisetso ea mocheso e itšetlehile ka bokhoni bo itseng ba mocheso.
2. Methara ea Phallo ea Boima ea Mofuta o sa Tobang
Hape di bitswa di-MFM tse “tswang”, tsena di kopanya dimithara tsa phallo ya modumo le di-sensor tse thusang ho bala phallo ya boima. Ditlhophiso tse tlwaelehileng di kenyeletsa:
- Methara ea Phallo ea Molumo + Methara ea Botenya: Turbine kapa ultrasound e lekanya sekhahla sa phallo, ha meter ea botenya (mohlala, fereko e thothomelang) e fana ka data ea botenya ba nako ea sebele. Phallo ea boima e baloa e le sehlahisoa sa phallo ea bophahamo le botenya.
- Limithara tse Lefelloang ke Khatello ea Mocheso: Bakeng sa maro a nang le likamano tse tsebahalang tsa khatello ea mocheso le khatello (mohlala, khase ea tlhaho), mithara ea bophahamo e kopantsoeng le li-sensor tsa mocheso/khatello e fetola lipalo ho latela maemo a tloaelehileng, e leng se etsang hore phallo ea boima e be ka tsela e sa tobang. Tsena li theko e tlaase empa ha li nepahale ho feta li-MFM tsa mofuta o tobileng, tse loketseng tlhokomelo ea indasteri e seng ea bohlokoa.
Likopo tsa Liindasteri le Mekhoa ea Khetho
Methapo ea phallo ea boima e sebeletsa mafapha a fapaneng:
- Oli le Khase: Li-CMFM li netefatsa tekanyo e nepahetseng ea mafura libakeng tsa ho hloekisa le khoebo e nepahetseng ea oli e tala.
- Lik'hemik'hale: Li-TMFM li hlokomela phallo ea khase e chefo kapa e senyang, ha li-CMFM li sebetsana le metsi a hlabang joalo ka li-polymer.
- Lijo le Dino: Di-CMFM tsa bohloeki (tse nang le dipeipi tsa tshepe e sa ruseng tsa 316L) di lekanya oli e jewang kapa dihlahiswa tsa lebese ntle le dikotsi tsa tshilafatso.
- Li-semiconductor: Li-TMFM li laola phallo ea khase e hloekileng haholo (mohlala, naetrojene, argon) tlhahisong ea li-chip.
Ha o khetha MFM, lintlha tsa bohlokoa li kenyelletsa:
- Matlotlo a Mokelikeli: Ho bola, ho teteana, le mokgahlelo (mokelikeli/khase/slurry) di laola ho tsamaellana ha thepa (mohlala, Hastelloy bakeng sa di-asidi).
- Litlhoko tsa ho Nepahala: Li-CMFM bakeng sa mesebetsi ea bohlokoa ea khoebo khahlanong le li-MFM tse sa tobang tse theko e tlaase bakeng sa tlhokomelo e akaretsang.
- Litšitiso tsa ho Kenya: Li-TMFM li hloka sebaka se senyenyane, ha li-CMFM li mamella phaephe e otlolohileng e fokolang.
Qetellong, dimithara tsa phallo ya boima di fetotse tekanyo ya phallo ka ho beha pele ho nepahala le ho tshepahala. Ho tloha ho dimithara tsa Coriolis tse nepahetseng haholo ho isa ho meralo ya mocheso e theko e tlase, ho tenyetseha ha tsona ho netefatsa hore di fihlela ditlhoko tsa ditshebetso tsa sejwalejwale tsa indasteri, ho kganna bokgoni le boleng diketaneng tsa phepelo ya lefatshe.
