Maemong a tekanyo ea phallo ea indasteri, tikoloho le ea masepala, limithara tsa phallo ea Doppler li hlahile e le tharollo e tšepahalang le e feto-fetohang, e khetholloang ka molao-motheo oa tsona o ikhethang oa ts'ebetso—ho sebelisa phello ea Doppler ho bala lebelo la phallo ka ho lemoha liphetoho tsa maqhubu a maqhubu a molumo a bonahatsoang ke likaroloana kapa lipululana ka har'a mokelikeli. Moralo ona o li fa melemo e mengata e sebetsanang le mefokolo ea limithara tsa phallo tsa setso, e leng se etsang hore li be tsa bohlokoa haholo maemong a rarahaneng a ts'ebeliso.
1. Ho Ikamahanya ka ho Ikhethang le Metsi a Turbid kapa a Lahliloeng ke Likaroloana
Ho fapana le mahlale a mangata a ho lekanya phallo (joalo ka limithara tsa nako ea transit ea ultrasonic kapa limithara tsa electromagnetic), limithara tsa phallo ea Doppler li atleha ka har'a metsi a nang le lintho tse tiileng tse emisitsoeng, lipululana, kapa mongobo o mongata—maemo a atisang ho sitisa lisebelisoa tse ling. Ebang ke ho lekanya metsi a litšila ka sediment, litšila tsa indasteri tse nang le seretse, kapa metsi a nosetsang ka likaroloana tsa tlhaho, molao-motheo oa Doppler o itšetleha ka likaroloana tsena e le "li-reflector" bakeng sa maqhubu a molumo. Sena se felisa kotsi ea tahlehelo ea lets'oao kapa ho senyeha ha ho nepahala, ho netefatsa ts'ebetso e tsitsitseng libakeng tse thata tsa metsi moo ho nepahala ho leng bohlokoa bakeng sa ho latela melao (mohlala, tlhokomelo ea ho ntša metsi a litšila tikolohong) kapa taolo ea ts'ebetso (mohlala, ho tsamaisa seretse merafong).
2. Ho kenya ho tenyetsehang ka Phetoho e Nyenyane ea Liphaephe
Methapo ea phallo ea Doppler e tšehetsa ho kenngoa ha liphaephe tse ka hare le tse ka hare, e fana ka ho tenyetseha ho sa bapisoeng le ho feta bakeng sa litsamaiso tsa liphaephe tse seng li ntse li le teng kapa tse ncha. Ka ho khetheha, mehlala ea liphaephe tse ka hare ha e hloke ho khaoloa, ho koaloa ha ts'ebetso, le ho kopana ka ho toba le mokelikeli—ho qoba likotsi tsa ho lutla, tšilafalo, kapa tšitiso ea ts'ebetso. Ena ke phetoho e kholo bakeng sa merero ea ho lokisa bocha (mohlala, ho ntlafatsa marang-rang a khale a metsi a masepala) kapa liindasteri moo botšepehi ba liphaephe bo sa buisanoeng (mohlala, ts'ebetso ea lijo, tlhahiso ea meriana). Esita le mehlala e ka hare e na le meralo e menyenyane e lekanang liphaephe tse nyane (ho fihlela ho DN25), e fokotsang litlhoko tsa sebaka le ho rarahana ha ho kenngoa ha li bapisoa le limithara tse kholo tsa mechini.
3. Litlhoko tse Tlase tsa Tlhokomelo le Bophelo bo Bolelele ba Tšebeletso
Kaha ha ho na likarolo tse tsamaeang tse kopanang le mokelikeli, li-flow meter tsa Doppler li fokotsa ho tsofala, ho silafala, le ho hloleha ha mechine—libaka tse tloaelehileng tsa bohloko ba turbine ea setso kapa li-positive-displacement metres. Ho ba sieo ha likarolo tsa ka hare (tse kang li-rotor kapa li-electrode) ho bolela hore ha ho na kotsi ea ho koaloa ke likaroloana kapa ho bola ho tsoa ho metsi a mabifi. Tlhokomelo ea kamehla hangata e kenyelletsa feela ho hloekisa li-transducer tsa kantle (bakeng sa mehlala ea clamp-on) kapa ho lekanya nako le nako, ho fokotsa nako ea ho se sebetse le litšenyehelo tsa ts'ebetso. Libakeng tsa indasteri tse nang le ts'ebetso ea 24/7 (mohlala, lifeme tsa lik'hemik'hale, liteishene tsa motlakase), ts'epo ena e fetolela ts'ebetsong e tsitsitseng ea nako e telele, hangata ka bophelo ba ts'ebeletso ba lilemo tse 8-10 kapa ho feta.
4. Ho nepahala ho Hoholo Maemong a Phallo e Feto-fetohang
Methapo ea phallo ea Doppler ea sejoale-joale e kopanya mahlale a tsoetseng pele a ts'ebetso ea matšoao (joalo ka ho sefa ho ikamahanyang le maemo le ho holisa matšoao a dijithale) ho fana ka litekanyo tse nepahetseng esita le libakeng tse fetohang tsa phallo. Li boloka ho nepahala ka hare ho ±1% ho isa ho ±3% ea boleng bo lekantsoeng ho pholletsa le karolelano e pharaletseng ea ho theoha ha motlakase (ho fihlela ho 1:100), ho akaretsa sekhahla se tlase le se phahameng sa phallo. Sena se bohlokoa haholo lits'ebetsong tse nang le tlhoko e feto-fetohang, joalo ka ho lekola metsi a pula (moo sekhahla sa phallo se nyolohang nakong ea pula) kapa ts'ebetso ea sehlopha sa indasteri (moo phallo e fetohang ka potoloho ea tlhahiso). Ho fapana le limithara tse ling tse hlokang ho matha ha liphaephe tse tsitsitseng, tse otlolohileng, mehlala ea Doppler e mamella litšitiso tse itekanetseng tsa phallo (mohlala, ho kobeha, li-valve tse haufi), ho fokotsa tlhoko ea liphetoho tse turang tsa liphaephe ho ntlafatsa maemo a phallo.
5. Katleho ea Litšenyehelo bakeng sa Likopo tse Fapaneng
Ha ho bapisoa le limithara tse khethehileng tse etselitsoeng maro a matla (mohlala, limithara tsa motlakase tse sa senyeheng bakeng sa maro a litšila a asiti), limithara tsa phallo ea Doppler li fana ka tharollo e theko e tlaase ntle le ho beha ts'ebetso kotsing. Ho ikamahanya ha tsona le mefuta e mengata ea maro ho felisa tlhoko ea ho tsetela limithareng tse fapaneng bakeng sa lits'ebetso tse fapaneng - mohlala, mithara e le 'ngoe ea Doppler e ka lekanya metsi a litšila le metsi a pholileng fekthering ea tlhahiso. Ho feta moo, litšenyehelo tse tlase tsa ho kenya le ho hlokomela li fokotsa litšenyehelo tsohle tsa beng, e leng se etsang hore li fumanehe habonolo bakeng sa likhoebo tse nyane ho isa ho tse mahareng (li-SME) le libaka tse kholo tsa indasteri ka ho tšoana.
Qetello
Limithara tsa phallo ea Doppler li hlahella ka ho lekanya phallo ea sejoale-joale ka bokhoni ba tsona ba ho sebetsana le maro a rarahaneng, ho kenya ho tenyetsehang, tlhokomelo e tlase, le ho nepahala ho tšepahalang—ho sebetsana le liphephetso tse matla ka ho fetisisa tsa liindasteri tse fapaneng. Ho tloha tlhokomelong ea tikoloho ho isa taolong ea ts'ebetso ea indasteri, melemo ea tsona e ikhethang e li etsa khetho e khethiloeng bakeng sa lits'ebetso moo limithara tsa setso li haellang. Ha theknoloji e ntse e tsoela pele, lintlafatso tse ling ts'ebetsong ea matšoao le khokahano (mohlala, kopanyo ea IoT bakeng sa tlhokomelo ea data ea nako ea sebele) li tla ntlafatsa boleng ba tsona feela, li tiise karolo ea tsona tsamaisong e sebetsang hantle, e tsamaisoang ke data.
