Metsi a nang le Dikaroloana tse Leketlileng kapa Dipululana
Dopplerlimithara tsa phallo ea ultrasonicli loketse haholo ho lekanya phallo ea maro a nang le lintho tse tiileng tse emisitsoeng kapa lipululana tsa khase. Lits'ebetsong tsa indasteri tse kang merafo, moo slurry (motsoako oa metsi le likaroloana tse tiileng) e tsamaisoang ka liphaephe, limithara tsena li ka lekanya sekhahla sa phallo ka nepo. Likaroloana tse tiileng tse ka har'a slurry, tse ka tlohang ho phofo e tšesaane ho isa ho lithollo tse kholo, li sebetsa e le li-reflector bakeng sa maqhubu a ultrasound. Ha slurry e ntse e tsamaea, likaroloana li baka phetoho ea Doppler khafetsa ea matšoao a ultrasound a bonahatsoang. Ka mokhoa o ts'oanang, lifemeng tsa kalafo ea metsi a litšila, boteng ba lintho tse fapaneng tse emisitsoeng tsa tlhaho le lithōle tse tiileng li lumella li-flowmeter tsa Doppler tsa ultrasonic ho sebetsa hantle. Limithara li ka sebetsana le sebopeho se rarahaneng le se fetohang hangata sa metsi a litšila, li fana ka litekanyo tse tšepahalang tsa sekhahla sa phallo bakeng sa taolo e nepahetseng ea ts'ebetso ea kalafo. Indastering ea oli le khase, nakong ea tlhahiso ea oli, mokelikeli hangata o na le lipululana tsa khase. Li-flowmeter tsa Doppler tsa ultrasonic li ka lekanya phallo ea maro a joalo a mekhahlelo e mengata ka nepo, ho nahanoa ka monehelo oa mekhahlelo ea metsi le khase ho phallo eohle.
Phallo ka Likanale tse Bulehileng
Limithara tsena tsa phallo li boetse lia sebetsa le phallong ea kanale e bulehileng, joalo ka linokeng, likanaleng tsa nosetso, le liphaepheng tsa metsi a pula. Tekolong ea noka, limithara tsa phallo ea ultrasonic tsa Doppler li ka kenngoa marokhong kapa mabopong a noka. Phallo ea tlhaho ea noka, e ka 'nang ea jara likaroloana tsa sediment, e fana ka li-scatter tse hlokahalang bakeng sa maqhubu a ultrasound. Ka ho lekanya phetoho ea Doppler ea maqhubu a bonahalitsoeng, lebelo la phallo libakeng tse fapaneng ho pholletsa le karolo ea noka le ka fumanoa. Lintlha tsena li ka sebelisoa ho bala sekhahla sa phallo ea volumetric ea noka. Litsamaisong tsa nosetso, moo metsi a ajoang ka likanaleng tse bulehileng,Limithara tsa phallo ea ultrasound tsa Dopplerthusa ho lekanya ka nepo bongata ba metsi a iswang masimong. Sena se bohlokwa bakeng sa taolo e sebetsang hantle ya metsi le ho netefatsa hore dijalo di fumana metsi a lekaneng. Tsamaisong ya metsi a pula ditoropong, dimithara di ka sebediswa ho lekola phallo ya metsi a pula diphaepheng tsa metsi, tseo hangata di nang le ditshila le mashala, e leng se thusang ho rala le ho laola mehato ya thibelo ya dikgohola hantle.
Phallo ea Lebelo le Phahameng
Limithara tsa phallo ea ultrasound tsa Dopplere ka lekanya ka katleho phallo ea mokelikeli o lebelo le phahameng. Litšebelisong tsa indasteri joalo ka lifeme tsa motlakase oa metsi, moo metsi a ntšoang ka lebelo le phahameng ka har'a li-penstock ho khanna li-turbine, limithara tsena li ka lekanya sekhahla sa phallo ka nepo. Metsi a lebelo le phahameng a na le lipululana tse nyane tsa moea tse kenelletsoeng nakong ea ts'ebetso, tse sebetsang e le li-reflector bakeng sa maqhubu a ultrasonic. Bokhoni ba li-meter tsa phallo ea ultrasonic tsa Doppler ho sebetsana le phallo ea lebelo le phahameng ntle le tahlehelo e kholo ea ho nepahala li etsa hore e be sesebelisoa sa bohlokoa maemong a joalo a tlhahiso ea matla. Lits'ebetsong tse ling tsa lik'hemik'hale, phallo ea lebelo le phahameng ea metsi a senyang kapa a khopisang e tloaelehile. Tlhaho e sa kenelleng ea Doppler ultrasoniclimithara tsa phallo(kaha hangata li kenngoa kantle ho phaephe kapa kanale) li etsa hore li lokele ho lekanya phallo ena ea lebelo le phahameng, kaha ha li kotsing ea ho senyeha le ho taboha ho ka amang limithara tsa phallo tsa moetlo tse ka hare ho mola.
Maemo a Mabe a Tikoloho
Hape li khona ho sebetsa maemong a thata a tikoloho. Libakeng tsa indasteri tse nang le mocheso o feteletseng, joalo ka lifemeng tsa tšepe moo mocheso o ka bang holimo haholo, kapa mesebetsing ea oli le khase ea Arctic moo mocheso o leng tlase haholo, li-Doppler ultrasonic flow metres li ka sebetsa ka mokhoa o tšepahalang. Kaho ea tsona e matla le taba ea hore ha li hloke ho kopana ka kotloloho le mokelikeli (ntle le li-transducer tsa ultrasonic tse ka etsoang ho mamella maemo a thata) li etsa hore li lokele libaka tsena. Ho phaella moo, libakeng tse nang le maemo a holimo a tšitiso ea motlakase, joalo ka li-transformer tse kholo tsa motlakase kapa lifemeng tsa indasteri tse nang le palo e kholo ea li-motor tsa motlakase,Limithara tsa phallo ea ultrasound tsa Dopplerli ka sireletsoa ho netefatsa ts'ebetso e nepahetseng. Li ka boela tsa sebelisoa libakeng tseo mokelikeli o senyang, ha feela li-transducer tsa ultrasonic li entsoe ka thepa e loketseng e hanelang mafome.
Ha re phethela,Limithara tsa phallo ea ultrasound tsa Dopplerli tenyetseha haholo 'me li fumana lits'ebetso maemong a fapaneng a mosebetsi, ho tloha ho sebetsana le maro a nang le lintho tse emisitsoeng ho ea ho sebetsa libakeng tse thata le ho lekanya phallo ea lebelo le phahameng maemong a fapaneng a indasteri le a tikoloho.
