Njengoko ingqwalasela yehlabathi kulondolozo lwamanzi kunye nokwakhiwa kwesixeko esikrelekrele, iimitha zamanzi ze-ultrasonic ziye zavela njengendlela entsha yokutshintsha indawo yeemitha zamanzi zemveli zoomatshini. Ngokungafaniyo neemitha zamanzi ezixhomekeke kwiindawo ezihambayo, iimitha zamanzi ze-ultrasonic zisebenzisa itekhnoloji ye-acoustic ukulinganisa ukuhamba kwamanzi, zibonelela ngokuchaneka okuphezulu, ukuqina, kunye nokunxibelelana okukrelekrele. Zisetyenziswa kakhulu kumacandelo okuhlala, orhwebo, kunye nemizi-mveliso, zidlala indima ebalulekileyo ekuphuculeni ulawulo lwemithombo yamanzi kunye nokunciphisa inkunkuma yamanzi.
Umgaqo oyintloko wokusebenza kweemitha zamanzi ze-ultrasonic usekelwe kwindlela yokwahluka kwexesha lokuhamba. Ii-transducers ezimbini ze-ultrasonic zifakelwe kumbhobho, zikhupha kwaye zifumana imiqondiso ye-acoustic ngokutshintshana kwicala lokuhamba kwamanzi nanxamnye nawo. Xa amanzi ehamba ngombhobho, akhawulezisa isignali ehamba kunye nokuhamba kwaye anciphise isignali ehamba ngokuchasene nawo. Imitha ibala umahluko wexesha phakathi kwemiqondiso emibini isebenzisa ifomula ethi Δt = (2L·v)/(c² - v²), apho uL ngumgama phakathi kwee-transducers, u-v ngumlinganiselo wamanzi, kwaye u-c ngumlinganiselo wesandi emanzini. Lo mahluko wexesha uguqulwa ube kukufundwa kwesantya sokuhamba kwevolumu echanekileyo.
Inzuzo ebalaseleyo yeemitha zamanzi ze-ultrasonic kukuba aziyilwanga ngoomatshini. Ngaphandle kweegiya, ii-impeller, okanye ezinye izinto ezihambayo, ziyasusa ukuguguleka okubangelwa kukuhamba kwamanzi, intlenga, okanye ukungcola. Olu yilo alugcini nje ngokwandisa ubomi benkonzo yemitha ukuya kwiminyaka eli-10-15—ixesha elide kakhulu kuneemitha zoomatshini—kodwa lukwathintela iimpazamo zokulinganisa ngenxa yokuguga okanye ukuxinana kwenxalenye. Ukongeza, ukuchaneka kwazo okuphezulu (ngokwesiqhelo ±0.2% ukuya ±1% yokufunda) kuqinisekisa idatha ethembekileyo nokuba kumanqanaba okuhamba aphantsi, nto leyo efumanisa ngokufanelekileyo ukuvuza kwamanzi okusoloko kuphosakele kwiimitha zoomatshini.
Ukusebenza okukrelekrele lolunye uphawu oluphambili oluqhuba ukwamkelwa kweemitha zamanzi ze-ultrasonic. Iimodeli zanamhlanje zidibanisa ukucutshungulwa kwesignali yedijithali, unxibelelwano olungenazingcingo (njengeLoRa, NB-IoT, okanye iWi-Fi), kunye nokukwazi ukugcina idatha. Zinokudlulisa idatha yokuhamba ngexesha langempela kwiiplatifomu zolawulo ezisekwe kwilifu, zivumela ukujonga kude, ukufundwa kwemitha ngokuzenzekelayo, kunye nokubhaqwa kokuvuza. Kubasebenzisi bokugqibela, oku kuthetha ukufikelela ngokulula kwidatha yokusetyenziswa kwamanzi ngeeapps zeselfowuni, kubanceda balungise imikhwa yokusebenzisa kunye nokunciphisa iindleko. Kwizibonelelo zamanzi, kwenza kube lula ukulawula iinqwelomoya, kunciphisa iindleko zomsebenzi wesandla, kwaye kuphucula ukusebenza kakuhle.
Iimitha zamanzi ze-ultrasonic zisebenziseka lula kwaye zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Kwizakhiwo zokuhlala, zibonelela ngezaziso ezichanekileyo zokuhlawulisa kunye nokuvuza, zikhusela abanini bezindlu kwiindleko ezingeyomfuneko. Izakhiwo zorhwebo kunye nezoshishino zizisebenzisa ukujonga ukusetyenziswa kwamanzi kwiinkqubo zemveliso, ukuphucula ukwabiwa kwezixhobo, kunye nokuthobela imigaqo yokusingqongileyo. Kwizixeko ezikrelekrele, zenza inxalenye ebalulekileyo yegridi yamanzi ekrelekrele, zivumela ulawulo oluphakathi lwenethiwekhi yokubonelela ngamanzi kunye nokuxhasa ukwenziwa kwezigqibo eziqhutywa yidatha zokulondolozwa kwamanzi.
Ukuqinisekisa ukusebenza kakuhle, kufuneka kuqwalaselwe izinto ezininzi zokufakela nokugcina izinto zisemgangathweni. Ezi mitha zifuna ukulungelelaniswa kakuhle kwemibhobho kunye neendawo ezaneleyo zemibhobho ethe tye phezulu nasezantsi ukuze kuthintelwe ukuphazamiseka kokuhamba kwamanzi. Zifanele zifakwe kwiindawo ezingenazo ukuphazamiseka okukhulu kwe-electromagnetic kunye nobushushu obugqithisileyo. Ngokungafaniyo neemitha zoomatshini, iimitha zamanzi ze-ultrasonic zifuna ukugcinwa okuncinci—ukulinganiswa rhoqo rhoqo emva kweminyaka emi-3-5 kunye nokucocwa rhoqo kombhobho ukuze kususwe inkunkuma enzima kudla ngokwanela ukugcina ukuchaneka.
Njengoko ukunqongophala kwamanzi kuba yingxaki engxamisekileyo kwihlabathi liphela, iimitha zamanzi ze-ultrasonic zilungele ukudlala indima ebaluleke ngakumbi kulawulo lwamanzi oluzinzileyo. Ukudibana kwazo kokuchaneka okuphezulu, ukuqina, kunye nokunxibelelana okukrelekrele kujongana nemida yeemitha zemveli, nto leyo eyenza zibe yintsika yeziseko zamanzi zanamhlanje. Ngokubonelela ngedatha ethembekileyo kunye nokuvumela ukwabiwa kwezixhobo ngokufanelekileyo, iimitha zamanzi ze-ultrasonic zinegalelo kwikamva elinokusetyenziswa kwamanzi kakuhle kuluntu nakumashishini kwihlabathi liphela.
