Besilokhu silinganisa isivinini somoya sisebenzisa ama-anemometer amakhulu eminyaka, kodwa intuthuko yakamuva yenze kwaba nokwenzeka ukunikeza izibikezelo zezulu ezithembekile nezinembile. Ama-anemometer e-Sonic alinganisa isivinini somoya ngokushesha nangokunembile uma kuqhathaniswa nezinguqulo zendabuko.
Izikhungo zesayensi yesimo sezulu zivame ukusebenzisa la madivayisi lapho zenza izilinganiso ezijwayelekile noma izifundo ezinemininingwane ukusiza ekwenzeni izibikezelo zezulu ezinembile zezindawo ezahlukahlukene. Izimo ezithile zemvelo zingase zikhawulele izilinganiso, kodwa kungenziwa izinguquko ezithile ukuze kunqotshwe lezi zinkinga.
Ama-anemometer avele ngekhulu le-15 futhi aqhubekile nokuthuthukiswa eminyakeni yamuva nje. Ama-anemometer endabuko, aqala ukwakhiwa maphakathi nekhulu le-19, asebenzisa ukuhlelwa okujikelezayo kwezinkomishi zomoya ezixhunywe ku-data logger. Ngawo-1920, aba mathathu, anikeza impendulo esheshayo nehambisanayo esiza ekulinganiseni izivunguvungu zomoya. Ama-anemometer e-Sonic manje ayisinyathelo esilandelayo ekubikezeleni isimo sezulu, anikeza ukunemba okukhulu kanye nesisombululo.
Ama-anemometer e-Sonic, athuthukiswe ngawo-1970, asebenzisa amagagasi e-ultrasonic ukukala isivinini somoya ngokushesha nokunquma ukuthi amagagasi omsindo ahamba phakathi kwezinzwa ezimbili ayasheshiswa noma ayehliswa umoya.
Manje sezithengiswa kakhulu futhi zisetshenziswa ezinhlosweni nasezindaweni ezahlukahlukene. Ama-anemometer e-sonic anezinhlangothi ezimbili (isivinini somoya kanye nesiqondiso) asetshenziswa kabanzi eziteshini zesimo sezulu, ekuthuthweni, kuma-wind turbine, ezindizeni, ngisho naphakathi nolwandle, entanta kuma-weather buoys.
Ama-anemometer e-Sonic angenza izilinganiso ezinesinqumo sesikhathi esiphezulu kakhulu, ngokuvamile kusukela ku-20 Hz kuya ku-100 Hz, okwenza zifaneleke kahle ekulinganisweni kwe-turbulence. Isivinini kanye nezixazululo kulezi zigaba zivumela izilinganiso ezinembe kakhudlwana. I-anemometer ye-sonic ingenye yezinsimbi zezulu ezintsha eziteshini zezulu namuhla, futhi ibaluleke kakhulu kune-wind vane, elinganisa isiqondiso somoya.
Ngokungafani nezinguqulo zendabuko, i-anemometer ye-sonic ayidingi izingxenye ezihambayo ukuze isebenze. Zilinganisa isikhathi esithathwayo ukuze i-pulse yomsindo ihambe phakathi kwezinzwa ezimbili. Isikhathi sinqunywa yibanga eliphakathi kwalezi zinzwa, lapho ijubane lomsindo lincike ekushiseni, ingcindezi kanye nokungcola komoya okufana nokungcola, usawoti, uthuli noma inkungu emoyeni.
Ukuze kutholakale ulwazi lwesivinini somoya phakathi kwezinzwa, inzwa ngayinye isebenza ngokushintshana njengomthumeli kanye nomemukeli, ngakho-ke ama-pulse adluliselwa phakathi kwazo zombili izinhlangothi.
Isivinini sokundiza sinqunywa ngokusekelwe esikhathini sokushaya kwenhliziyo ohlangothini ngalunye; sibamba isivinini somoya esinezinhlangothi ezintathu, isiqondiso kanye ne-engeli ngokubeka amabhangqa amathathu ezinzwa kuma-axes amathathu ahlukene.
Isikhungo Sezesayensi Yomoya sinama-anemometer ayishumi nesithupha e-sonic, elinye lawo likwazi ukusebenza ku-100 Hz, amabili awo akwazi ukusebenza ku-50 Hz, kanti amanye, anamandla kakhulu okusebenza ku-20 Hz, ashesha ngokwanele emisebenzini eminingi.
Amathuluzi amabili afakwe ukushisa okuvimbela iqhwa ukuze kusetshenziswe ezimweni ezibandayo. Iningi lawo linokufakwa kwe-analog, okuvumela ukuthi wengeze izinzwa ezengeziwe ezifana nokushisa, umswakama, ingcindezi kanye namagesi okulandelela.
Ama-anemometer e-Sonic asetshenziswe kumaphrojekthi afana ne-NABMLEX ukukala isivinini somoya ezindaweni eziphakeme ezahlukene, kanti i-Cityflux ithathe izilinganiso ezahlukene ezingxenyeni ezahlukene zedolobha.
Ithimba lephrojekthi yeCityFlux, elifunda ngokungcola komoya emadolobheni, lithe: “Ingqikithi yeCityFlux ukutadisha zombili lezi zinkinga ngesikhathi esisodwa ngokulinganisa ukuthi imimoya enamandla isusa ngokushesha kangakanani izinto ezincane kunethiwekhi 'yemihosha' yasedolobheni. Umoya ongaphezulu kwazo yilapho sihlala futhi siphefumula khona. Indawo engapheshulwa umoya.”
Ama-anemometer e-Sonic ayintuthuko enkulu yakamuva ekulinganisweni kwesivinini somoya, athuthukisa ukunemba kwezibikezelo zesimo sezulu futhi avikeleke ezimweni ezimbi njengemvula enkulu engabangela izinkinga ngamathuluzi endabuko.
Idatha yesivinini somoya enembile kakhulu isisiza siqonde izimo zezulu ezizayo futhi silungiselele impilo yansuku zonke nomsebenzi.
