Re ’nile ra lekanya lebelo la moea re sebelisa li-anemometer ka makholo a lilemo, empa tsoelo-pele ea morao tjena e entse hore ho khonehe ho fana ka likhakanyo tsa boemo ba leholimo tse tšepahalang le tse nepahetseng haholoanyane. Li-anemometer tsa Sonic li lekanya lebelo la moea kapele le ka nepo ha li bapisoa le mefuta ea setso.
Litsi tsa mahlale a sepakapaka hangata li sebelisa lisebelisoa tsena ha li etsa litekanyo tsa kamehla kapa lithuto tse qaqileng ho thusa ho etsa likhakanyo tse nepahetseng tsa boemo ba leholimo bakeng sa libaka tse fapaneng. Maemo a itseng a tikoloho a ka 'na a fokotsa litekanyo, empa liphetoho tse itseng li ka etsoa ho rarolla mathata ana.
Li-anemometer li hlahile lekholong la bo15 la lilemo 'me li ntse li tsoela pele ho ntlafatsoa le ho ntlafatsoa lilemong tsa morao tjena. Li-anemometer tsa setso, tse qalileng ho ntlafatsoa bohareng ba lekholo la bo19 la lilemo, li sebelisa tokisetso e chitja ea likopi tsa moea tse hokahaneng le data logger. Lilemong tsa bo-1920, li ile tsa fetoha tse tharo, tsa fana ka karabelo e potlakileng le e tsitsitseng haholoanyane e thusang ho lekanya moea o fokang. Li-anemometer tsa Sonic joale ke mohato o latelang oa ho bolela esale pele boemo ba leholimo, o fanang ka ho nepahala le qeto e kholoanyane.
Li-anemometer tsa Sonic, tse qapiloeng lilemong tsa bo-1970, li sebelisa maqhubu a ultrasound ho lekanya lebelo la moea hang-hang le ho fumana hore na maqhubu a molumo a tsamaeang pakeng tsa li-sensor tse peli a ntse a potlakisoa kapa a fokotsoa ke moea.
Hona jwale di se di rekiswa haholo mme di sebediswa mererong le dibakeng tse fapaneng. Di-anemometer tsa sonic tsa mahlakore a mabedi (lebelo la moya le tataiso) di sebediswa haholo diteisheneng tsa boemo ba lehodimo, dikepeng, diturbineng tsa moya, difofaneng, esita le bohareng ba lewatle, di phaphametse hodima di-buoy tsa boemo ba lehodimo.
Li-anemometer tsa Sonic li ka etsa litekanyo ka qeto e phahameng haholo ea nako, hangata ho tloha ho 20 Hz ho isa ho 100 Hz, e leng se etsang hore li tšoanelehe hantle bakeng sa litekanyo tsa turbulence. Lebelo le liqeto mefuteng ena li lumella litekanyo tse nepahetseng haholoanyane. Anemometer ea sonic ke e 'ngoe ea lisebelisoa tse ncha tsa boemo ba leholimo liteisheneng tsa boemo ba leholimo kajeno, 'me e bohlokoa le ho feta vene ea moea, e lekanyang tataiso ea moea.
Ho fapana le mefuta e tloaelehileng, anemometer ea molumo ha e hloke likarolo tse tsamaeang hore e sebetse. Li lekanya nako eo ho e nkang hore molumo o tsamaee pakeng tsa li-sensor tse peli. Nako e khethoa ke sebaka se pakeng tsa li-sensor tsena, moo lebelo la molumo le itšetlehileng ka mocheso, khatello le litšila tsa moea tse kang tšilafalo, letsoai, lerōle kapa moholi moeeng.
Ho fumana tlhahisoleseding ya lebelo la moya pakeng tsa di-sensor, sensor e nngwe le e nngwe e sebetsa ka ho fapanyetsana e le transmitter le receiver, kahoo di-pulse di fetisetswa pakeng tsa tsona ka mahlakoreng ka bobedi.
Lebelo la sefofane le khethoa ho latela nako ea ho otla ha pelo lehlakoreng le leng le le leng; e hapa lebelo la moea la mahlakore a mararo, tataiso le sekhutlo ka ho beha lipara tse tharo tsa li-sensor li-axes tse tharo tse fapaneng.
Setsi sa Saense ea Sepakapaka se na le li-anemometer tse leshome le metso e tšeletseng tsa molumo, e 'ngoe ea tsona e khona ho sebetsa ka 100 Hz, tse peli tsa tsona li khona ho sebetsa ka 50 Hz, 'me tse ling, tse nang le bokhoni ba ho sebetsa ka 20 Hz, li potlakile ka ho lekaneng bakeng sa ts'ebetso e ngata.
Lisebelisoa tse peli li na le ho futhumatsa ho thibelang leqhoa bakeng sa tšebeliso maemong a leqhoa. Bongata ba tsona li na le lintho tse kenang tsa analog, tse u lumellang ho eketsa li-sensor tse ling tse kang mocheso, mongobo, khatello le likhase tse sa bonahaleng.
Li-anemometer tsa Sonic li 'nile tsa sebelisoa mererong e kang NABMLEX ho lekanya lebelo la moea libakeng tse fapaneng, 'me Cityflux e nkile litekanyo tse fapaneng likarolong tse fapaneng tsa toropo.
Sehlopha sa projeke ea CityFlux, se ithutang tšilafalo ea moea litoropong, se itse: "Sehlooho sa CityFlux ke ho ithuta mathata ana ka bobeli ka nako e le 'ngoe ka ho lekanya hore na meea e matla e tlosa lintho tse nyenyane ka potlako hakae marang-rang a 'likhohlo' tsa literateng tsa toropo. Moea o ka holimo ho tsona ke moo re lulang le ho hema teng. Sebaka seo moea o ka fokang ho sona."
Li-anemometer tsa Sonic ke tsoelo-pele e kholo ea morao-rao ea ho lekanya lebelo la moea, e ntlafatsang ho nepahala ha likhakanyo tsa boemo ba leholimo le ho itšireletsa maemong a mabe a kang pula e matla e ka bakang mathata ka lisebelisoa tsa setso.
Lintlha tse nepahetseng haholoanyane tsa lebelo la moea li re thusa ho utloisisa maemo a leholimo a tlang le ho itokisetsa bophelo ba letsatsi le letsatsi le mosebetsi.
