Ho tloha masimong a oli a Bochabela bo Hare ho isa masimong a raese a Asia Boroa-bochabela, li-level meter—lisebelisoa tse lekanyang bophahamo ba metsi kapa lintho tse tiileng ka litankeng, likepeng, kapa matamong a tlhaho—ke lisebelisoa tsa bohlokoa ho pholletsa le liindasteri. Bokhoni ba tsona ba ho fana ka lintlha tsa nako ea sebele mabapi le bophahamo, botebo le litaba bo netefatsa katleho, polokeho le ntlafatso ea lisebelisoa, e leng se etsang hore e be tsa bohlokoa ts'ebetsong lefatšeng ka bophara. Sengoloa sena se hlahloba kamoo li-level meter li sebelisoang kateng libakeng le mafapheng a fapaneng, se totobatsa karolo ea tsona ho sebetsaneng le liphephetso tsa lehae le ho khanna tsoelo-pele ea lefats'e.
1. Lekala la Matla: Ho netefatsa Bokgoni ba Oli, Khase le Lisebelisoa tse Nchafatswang
Indastering ea eneji, ho lekanya boemo ka nepo ho bohlokoa bakeng sa ho ntša, ho boloka le ho tsamaisa mafura—ts'ebetso eo esita le liphoso tse nyane li ka lebisang tšenyo, likotsi kapa tahlehelo ea lichelete.
Bochabela bo Hare, moo ho nang le libaka tse fetang 48% tsa polokelo ea oli lefatšeng ka bophara (BP Statistical Review, 2023), limithara tsa ultrasonic le tsa radar li fumaneha hohle litankeng tsa polokelo ea oli. Setsi sa ho hloekisa sa Ras Tanura sa Saudi Arabia, se seng sa tse kholo ka ho fetisisa lefatšeng, se sebelisa limithara tsa radar tse sa amaneng le motho ho lekola maemo a oli e tala litankeng tse kholo tsa polokelo, ho mamella mocheso o feteletseng oa lehoatata (ho fihlela ho 50°C) le ho qoba ho kopana le li-hydrocarbon tse senyang. Methara ena e fetisetsa data lits'ebetsong tsa taolo tse bohareng, e nolofalletsang tsamaiso ea thepa e ikemetseng le ho fokotsa kotsi ea ho tlatsa ho feta tekano.
Amerika Leboea, keketseho ea khase ea shale e itšetlehile ka limithara tse bataletseng bakeng sa ts'ebetso ea sebaka se setle. Permian Basin ea Texas, limithara tse bataletseng li latela bongata ba seretse se chekiloeng ka har'a litanka tsa polokelo - tsa bohlokoa bakeng sa ho boloka khatello nakong ea ho qhaqha le ho thibela ho hloleha ha lisebelisoa. Ho sa le joalo, lefapheng la matla a nchafatsoang la Europe, limithara tse phaphametseng tsa boemo ba ultrasonic li hlokomela maemo a metsi matamong a metsi (joalo ka letamo la Tinnhølen la Norway), ho netefatsa phallo e ntle ea metsi ho liturbine le ho eketsa tlhahiso ea matla.
2. Temo: Ho Laola Khaello ea Metsi le Chai ea Lijalo
Temo e ikarabella bakeng sa 70% ea tšebeliso ea metsi a hloekileng lefatšeng ka bophara (UN Water), e leng se etsang hore li-level metres li be bohlokoa bakeng sa tsamaiso ea nosetso, haholo-holo libakeng tse haellang metsi.
Metseng e omeletseng ea Australia, moo komello e atileng, limithara tsa boemo ba radar li kenngoa matamong a mapolasi le likanaleng tsa nosetso ho latela mehloli ea metsi. Balemi ba sebelisa lintlha tsa nako ea sebele ho tsoa ho limithara tsena ho fetola kemiso ea ho nosetsa lijalo tsa koro le harese, ho fokotsa litšila tsa metsi ka ho fihla ho 30% ha ho bapisoa le liteko tsa setso tsa letsoho. Ka mokhoa o ts'oanang, sebakeng sa Punjab sa India—se tsejoang e le "seroto sa bohobe sa India"—limithara tsa boemo ba ultrasonic li hlahloba maemo a metsi a ka tlas'a lefatše lilibeng tsa lipeipi, li thusa ho laola ho ntšoa ha metsi le ho thibela ho fokotseha ha metsi a ka tlas'a lefatše, a theohileng ka limithara tse 3 lilemong tse leshome tse fetileng.
Asia Boroa-bochabela, temo ea raese e itšetlehile ka taolo e nepahetseng ea boemo ba metsi. Mekong Delta ea Vietnam, limithara tsa boemo tse tsamaisoang ka phaphamala (lisebelisoa tse bonolo, tse theko e tlaase) li boloka botebo ba metsi bo tsitsitseng masimong a raese—e leng tsa bohlokoa bakeng sa ho mela ha peo le kholo ea lijalo. Limithara tsena li etsa hore li-valve tse iketsang li eketse kapa li ntše metsi, li netefatse chai e tsitsitseng esita le nakong ea ho fetoha ha lipula tsa monsoon.
3. Metsi a Masepala le Metsi a Litšila: Ho Sireletsa Bophelo bo Botle ba Sechaba
Metse lefatšeng ka bophara e itšetlehile ka limithara tse bataletseng ho laola phepelo ea metsi a nooang le kalafo ea metsi a litšila, ho sireletsa bophelo bo botle ba sechaba le boleng ba tikoloho.
Afrika, moo phihlello ea metsi a hloekileng e fokolang, limithara tse bataletseng li bapala karolo ea bohlokoa kabong ea metsi. Nairobi, Kenya, limithara tse bataletseng tsa ultrasound li beha leihlo maemo a metsi litankeng tsa polokelo tsa masepala, e leng se nolofalletsang bolaoli ba metsi ba toropo ho beha pele ho isa metsi libakeng tse sa hlokeng tlhokomelo e lekaneng le ho fokotsa khaello. Nakong ea linako tsa komello, lintlha tse tsoang limithareng tsena li thusa ho thibela ho omella ha litanka, ho netefatsa phihlello e tsoelang pele ea metsi a hloekileng a nooang bakeng sa baahi ba fetang limilione tse 2.
Europe, lifeme tsa kalafo ea metsi a litšila (WWTPs) li sebelisa li-level metres ho ntlafatsa ts'ebetso. Berlin-Buch WWTP ea Jeremane, e 'ngoe ea tse kholo ka ho fetisisa Europe, e sebelisa li-level metres tsa khatello ka har'a litanka tsa sedimentation ho latela ho bokellana ha seretse. Lintlha tsa nako ea sebele li lemosa basebetsi ha seretse se hloka ho tlosoa, ho thibela ho koaleha le ho netefatsa hore fektheri e fihlela litekanyetso tsa tikoloho tsa EU bakeng sa ho ntša metsi a phekotsoeng. Amerika Leboea, metse e kang New York e sebelisa li-level metres tsa radar ka har'a litanka tsa metsi a sefefo ho laola likotsi tsa likhohola—nakong ea lipula tse matla, li-level metres li baka lipompo ho ntša metsi a mangata, ho fokotsa likhohola tsa litoropo libakeng tse tlaase.
4. Tlhahiso le Tsamaiso ea Litsamaiso: Ho Nolofatsa Ketane ea Tlhahiso le Phepelo
Tlhahisong, dimetara tsa maemo di netefatsa tlhahiso e tsitsitseng ka ho beha leihlo maemo a thepa e tala le a dihlahiswa tse fedisitsweng, ha lefapheng la thepa, di ntlafatsa polokelo le tsamaiso ya thepa.
Litsing tsa tlhahiso tsa Chaena (tse kang Profinse ea Guangdong), limithara tsa boemo ba capacitive li latela lik'hemik'hale tsa metsi (joalo ka li-solvent le likhomaretsi) litankeng tsa fektheri, li netefatsa hore phepelo e sa khaotseng ea likhokahano bakeng sa lisebelisoa tsa elektroniki le masela e fihla. Limithara tsena li fokotsa nako ea ho se sebetse ka ho lemosa basebetsi ka maemo a tlase pele li-stock li fela, ho tšehetsa karolo ea Chaena joalo ka moetapele oa lefats'e oa tlhahiso.
Sebakeng sa Amazon sa Brazil, moo thepa e itshetlehileng hodima dipalangwang tsa noka, dimithara tsa boemo ba ultrasound di lekola maemo a metsi dikoung le dinokeng. Nakong ya komello, maemo a theohang a noka a ka thiba dikepe tsa thepa—dimithara di fana ka data ya nako ya sebele ho dikhamphani tsa dikepe, e leng se di dumellang ho fetola ditsela kapa boholo ba mojaro le ho qoba tieho. Dikoung tsa lefatshe tse kang Rotterdam (Netherlands), dimithara tsa boemo ba radar di lekola maemo a dijo-thollo le mashala disilo tsa polokelo, e leng se nolofalletsang ho kenya thepa ka katleho dikepeng le ho fokotsa tahlehelo e bakwang ke ho tlatsa ho feta tekano kapa ho senyeha.
Qetello
Limithara tsa maemo li ka 'na tsa ba nyane ka boholo, empa tšusumetso ea tsona ke ea lefats'e ka bophara. Ho pholletsa le matla, temo, lits'ebeletso tsa masepala le tlhahiso, li sebetsana le liphephetso tse ikhethileng tsa libaka - ho tloha mochesong oa lehoatata oa Bochabela bo Hare ho ea komellong ea Australia le ho feto-fetoha ha linoka tsa Amazon - ha li ntse li khanna bokhoni le botsitso. Ha liindasteri li ntse li hola li hokahane haholoanyane ebile li tsamaisoa ke data, tlhoko ea limithara tsa maemo a tsoetseng pele (tse hlomelitsoeng ka bokhoni ba IoT bakeng sa ho lekola hole) e tla eketseha feela. Lefatšeng leo tsamaiso ea mehloli e leng ea bohlokoa, limithara tsa maemo ha se lisebelisoa feela - ke balekane ba bohlokoa ho haheng bokamoso bo sebetsang hantle le bo tiileng haholoanyane.
