Iimitha zokuhamba ze-ultrasonic zisetyenziswa kakhulu kumashishini ahlukeneyo ukulinganisa ukuhamba kolwelo kunye neegesi. Enye yezona mitha zokuhamba ze-ultrasonic zixhaphakileyo yimitha yokuhamba kwe-Doppler. Olu hlobo lwemitha yokuhamba lusebenzisa isiphumo se-Doppler ukulinganisa ukuhamba kolwelo oluneziqwenga ezixhonyiweyo okanye amaqamza omoya. Iimitha zokuhamba kwe-Doppler zisebenza ngakumbi kwiindawo apho ulwelo okanye igesi iqulethe ukungcola okanye iziqwenga eziqinileyo.
Kukho iintlobo ezininzi zeemitha zokuhamba nge-ultrasonic, nganye ineempawu zayo kunye nokusetyenziswa kwayo okwahlukileyo. Ukongeza kwiimitha zokuhamba nge-Doppler, ezinye iintlobo zeemitha zokuhamba nge-ultrasonic ziquka iimitha zokuhamba nge-transit kunye neemitha zokuhamba nge-open channel.
Iimitha zokuhamba kolwelo zihlala zisetyenziswa kwiindawo ezicocekileyo apho ulwelo lungenazo iinxalenye ezixhonyiweyo okanye amaqamza omoya. Ezi mitha zokuhamba kolwelo zisebenza ngokulinganisa umahluko kwixesha elithathwayo ukuze isignali ye-ultrasonic ihambe phezulu nasezantsi kolwelo. Ngokuthelekisa amaxesha ohambo, izinga lokuhamba kolwelo linokuqinisekiswa ngokuchanekileyo.
Kwelinye icala, ii-flowmeters zetshaneli evulekileyo zisetyenziselwa ukulinganisa ukuhamba kolwelo kwiitshaneli ezivulekileyo ezifana nemilambo, imilambo, kunye nemijelo. Ezi flowmeters zisebenzisa ii-ultrasound sensors ukulinganisa inqanaba kunye nesantya sokuhamba kolwelo, okuvumela ukubalwa kokuhamba ngokuchanekileyo.
Uhlobo ngalunye lwemitha yokuhamba kwe-ultrasonic luneengenelo kunye nemida yalo, nto leyo eyenza ukuba ifaneleke kwiindlela ezahlukeneyo zokusebenza. Iimitha zokuhamba kwe-Doppler zilungele ukusetyenziswa apho ulwelo okanye igesi iqulethe ukungcola okanye amasuntswana aqinileyo, ngelixa iimitha zokuhamba kwe-transit zilungele ukusetyenziswa kolwelo olucocekileyo. Iimitha zokuhamba kwe-open channel, kwelinye icala, zenzelwe ngokukodwa ukulinganisa ukuhamba kolwelo kwiindlela ezivulekileyo.
Ukongeza kwiimpawu ezithile zesicelo, iimitha zokuhamba nge-ultrasonic zibonelela ngeenzuzo ezininzi kuneteknoloji zokulinganisa ukuhamba kwezixhobo zemveli. Aziphazamisi, oko kuthetha ukuba azidibani nolwelo okanye iigesi ezihambayo, nto leyo enciphisa umngcipheko wokungcola okanye umonakalo kwimitha yokuhamba. Iimitha zokuhamba nge-ultrasonic zikwabonelela ngokuchanekileyo okuphezulu kwaye zinokulinganisa ukuhamba kwezixhobo ngokunciphisa uxinzelelo oluncinci, nto leyo ezenze zilungele ukusetyenziswa kwezixhobo ezahlukeneyo zoshishino.
Ukongeza, ii-flow meter ze-ultrasonic kulula ukuzifakela nokuzigcina, zifuna ixesha elincinci lokungasebenzi ukuze zifakelwe kwaye zilinganiswe. Ziyakwazi nokulinganisa ukuhamba kuzo zombini iindlela, nto leyo ezenza zilungele ukusetyenziswa apho icala lokuhamba linokutshintsha ngokuhamba kwexesha.
Ngamafutshane, iimitha zokuhamba nge-ultrasonic, kuquka i-Doppler, iimitha zokuhamba nge-transit kunye ne-open channel, zibonelela ngezisombululo ezahlukeneyo nezithembekileyo zokulinganisa ukuhamba kolwelo kunye negesi kwiindlela ezahlukeneyo zokusebenza kwezoshishino. Uhlobo ngalunye lwemitha yokuhamba nge-ultrasonic luneempawu zalo ezizodwa kunye nokusetyenziswa, ngoko ke kubalulekile ukukhetha uhlobo olufanelekileyo lwemitha yokuhamba ngokusekwe kwiimfuno ezithile zesicelo. Ngenxa yendalo yazo engangeneleliyo, ukuchaneka okuphezulu kunye nokulula kokufakwa, iimitha zokuhamba nge-ultrasonic zihlala zilukhetho oludumileyo lokulinganisa ukuhamba kwemveliso kwiindlela ezahlukeneyo.
