Iimitha zokuhamba ze-ultrasonic ziye zaba sisixhobo esibalulekileyo kwicandelo leenkqubo zoshishino kunye nokulinganisa ulwelo. Le teknoloji iphambili ibonelela ngendlela engangenisi ntsholongwane kwaye ichaneke kakhulu yokulinganisa ukuhamba kolwelo kunye negesi. Kodwa isebenza njani kanye kanye imitha yokuhamba kwe-ultrasonic? Makhe sijonge indlela esi sixhobo sitsha esisebenza ngayo ukuze siqonde ngcono ukusebenza kwaso.
Eyona nto iphambili kwi-ultrasonic flow meter kukusebenzisa umgaqo wetekhnoloji ye-ultrasonic ukulinganisa ukuhamba kolwelo. Esi sixhobo sinee-sensors ezibekwe ngobuchule ngaphandle kwemibhobho apho ulwelo luhamba khona. Ezi transducers zikhupha ii-ultrasonic pulses ezihamba ngolwelo kwaye zamkelwe yi-transducer echaseneyo. Ngokuhlalutya ixesha elithathwa yi-ultrasonic pulse ukuhamba phezulu nasezantsi, i-flow meter inokubala ngokuchanekileyo isantya solwelo.
Enye yezona nzuzo ziphambili zeemitha zokuhamba nge-ultrasonic kukuba azingenisi ntsholongwane. Ngokungafaniyo neemitha zokuhamba zemveli ezifuna ukudibana ngqo nolwelo, iimitha zokuhamba nge-ultrasonic zinokulinganisa ukuhamba ngaphandle kokuphazamisa indlela yokuhamba okanye ukubangela ukwehla koxinzelelo. Oku akunciphisi nje kuphela umngcipheko wongcoliseko kodwa kunciphisa neendleko zokugcina kunye nokusebenza.
Kukho iintlobo ezimbini eziphambili zeemitha zokuhamba kwe-ultrasonic: iimitha zokuhamba kwe-transit kunye neemitha zokuhamba kwe-Doppler. Iimitha zokuhamba kwe-ultrasonic zexesha le-transit zilungele ukulinganisa ulwelo olucocekileyo nolufanayo. Zisebenza ngokuthelekisa ixesha elithathwayo ukuze i-pulse ye-ultrasonic ihambe kunye nolwelo kwaye ichasene nalo. Olu vavanyo lokwahluka luvumela imitha yokuhamba kwe-flow ukuba imisele ngokuchanekileyo isantya sokuhamba kwe-flow. Iimitha zokuhamba kwe-ultrasonic ze-Doppler, kwelinye icala, zenzelwe ulwelo oluqulethe amasuntswana okanye amaqamza. Ezi zixhobo zixhomekeke kumgaqo we-Doppler effect, apho i-frequency ye-pulses ye-ultrasonic itshintsha ngenxa yokuhamba kwamasuntswana ngaphakathi kolwelo. Ngokuhlalutya ukutshintsha kwe-frequency, imitha yokuhamba kwe-flow inokubala isantya sokuhamba kwe-flow.
Ukongeza ekubeni aziphazamisi, ii-ultrasonic flow meter zibonelela ngokuchaneka okuphezulu kunye nokuthembeka. Ziyakwazi ukulinganisa uluhlu olubanzi lwamazinga okuhamba kwaye azichaphazeleki kutshintsho lobushushu, uxinzelelo okanye ukuxinana. Oku kuzenza zilungele ukusetyenziswa ngeendlela ezahlukeneyo kumashishini afana neoyile negesi, amanzi kunye namanzi amdaka, ukucubungula iikhemikhali kunye neenkqubo ze-HVAC.
Ukongeza, ii-ultrasonic flow meter kulula ukuzifakela nokuzilungisa. Ekubeni zingenazo iindawo ezishukumayo kwaye zingonakalisi kangako, ezi zixhobo zifuna ukulinganiswa okuncinci kwaye zibonelela ngokusebenza ixesha elide, okungenazingxaki.
Ngamafutshane, imigaqo yoomatshini yeemitha zokuhamba kwe-ultrasonic isekelwe kwimigaqo yetekhnoloji ye-ultrasonic, evumela ukulinganiswa kokuhamba kolwelo okungangenisi ntsholongwane kwaye ngokuchanekileyo kakhulu. Ngenxa yokuguquguquka kwazo, ukuthembeka kunye nokulula kokufakwa, iimitha zokuhamba kwe-ultrasonic ziye zaba sisixhobo esibalulekileyo kumashishini afuna izisombululo zokulinganisa ukuhamba ngokuchanekileyo nangokufanelekileyo. Njengoko itekhnoloji iqhubeka ihambela phambili, sinokulindela uyilo olongezelelweyo kuyilo lweemitha zokuhamba kwe-ultrasonic, ukuphucula ngakumbi ukusebenza kwayo kunye nokwandisa ukusetyenziswa kwayo.
