Ekuphathweni koketshezi lwezimboni, isidingo samathuluzi okulinganisa ahlanganisa ukunemba nokuphazamiseka okuncane kwenqubo senze ama-flowmeter e-ultrasonic abe yinto eshintsha umdlalo. Ngokungafani namadivayisi okulinganisa ukugeleza kwendabuko—njengamamitha e-turbine adinga izingxenye zangaphakathi ukuze asebenzisane noketshezi, noma amamitha okucindezela ahlukile abeka engcupheni yokuvaleka nokungcola—ama-flowmeter e-ultrasonic asebenza ngaphandle kokungena epayipini noma ukuthinta uketshezi ngokwalo. Lo mklamo ongahlaseli, ohambisana nobuchwepheshe obuthuthukisiwe bokucubungula isignali, ubavumela ukuthi banikeze idatha enembile kakhulu, bebhekana nezindawo ezibucayi ezimbonini ezisukela ekwelashweni kwamanzi kuya ku-oyili negesi, kanye nokukhiqizwa kwemithi.
Isimiso esiyinhloko ngemuva kwama-flowmeter e-ultrasonic sisekusebenziseni ukuziphatha kwamagagasi omsindo ukuze kubalwe ijubane loketshezi. Amamodeli amaningi ezimboni athembele kubuchwepheshe obubili obubalulekile: isikhathi sokuthutha kanye nomphumela we-Doppler, ngamunye wenzelwe izinhlobo ezithile zoketshezi kodwa ugxile ngokulinganayo ekungangenini. Ama-flowmeter e-ultrasonic e-transit-time asebenzisa ama-transducer amabili afakwe ngaphandle ebusweni bepayipi, elinye lidlulisela kanti elinye lithola izimpawu ze-ultrasonic. Lapho uketshezi lugeleza ngepayipi, isignali ehamba ngendlela yokugeleza (ezansi) ithatha isikhathi esincane ukufinyelela kumamukeli, kuyilapho isignali ehamba ngokumelene nokugeleza (ezansi) ithatha isikhathi eside. Imitha ibala umehluko wesikhathi phakathi kwalezi zimpawu ezimbili, bese isebenzisa le datha—kanye nobubanzi bepayipi kanye nezakhiwo zoketshezi—ukubala izinga lokugeleza ngokunemba okuphawulekayo, ngokuvamile ngaphakathi kwe-±0.5% yenani langempela loketshezi oluhlanzekile.
Kuma-fluid anezinhlayiya ezilengayo noma amabhamuza (njengamanzi angcolile, ama-slurry, noma uwoyela ongahluziwe), ama-flowmeter e-ultrasonic e-Doppler-effect ayathandwa. Lawa madivayisi akhipha amaza omsindo aphindaphindayo aphezulu aphuma ezinhlayiyeni eziku-fluid; amaza abonakalayo athola ukushintsha kwemvamisa (okwaziwa ngokuthi umphumela we-Doppler) ngokusekelwe kwijubane lezinhlayiya, elihlobene ngqo nesivinini sokugeleza koketshezi. Ngisho nalezi zinhlayiya, amamitha e-Doppler agcina ukunemba ngokuhlunga umsindo wangemuva, aqinisekisa ukufundwa okuthembekile ngaphandle kokudinga ukuphazamisa ukugeleza koketshezi noma ukuveza izingxenye ezintweni ezirhabaxa noma ezibolayo.
Indlela ama-flowmeter e-ultrasonic angangenisi ugesi ngayo iletha izinzuzo eziningi ezisebenzayo ezithuthukisa ukusebenza kahle kanye nokusebenza kahle kwezindleko. Ukufakwa akudingi ukusika amapayipi, ukushisela, noma ukuvala—ochwepheshe bamane banamathisele ama-transducer ngaphandle kwepayipi, okunciphisa isikhathi sokungasebenzi kusukela ezinsukwini (kumamitha avamile) kuya emahoreni noma ngisho nemizuzu. Lokhu kubaluleke kakhulu ezimbonini ezifana nokukhiqizwa kukagesi, lapho ukuphazamiseka kokugeleza kwamanzi okupholisa kungaholela ekunqamukeni okubizayo. Ngaphezu kwalokho, njengoba kungekho izingxenye zangaphakathi, ama-ultrasound metres agwema izinkinga ezifana nokuguguleka, ukuvaleka, noma ukungcola koketshezi—izinkinga ezihlupha i-turbine noma amamitha okuhambisa amahle. Ekukhiqizeni imithi, isibonelo, lokhu kusho ukuthi akukho bungozi bezinhlayiya zensimbi ezivela ezingxenyeni ezigugile ezingene zibe msulwa kakhulu, okuqinisekisa ukuhambisana nezindinganiso eziqinile zomthetho.
Ukunemba okuphezulu kungenye indlela enamandla achazayo, eyenzeka ngenxa yentuthuko ekucutshungulweni kwesignali yedijithali kanye nobuchwepheshe bezinzwa. Ama-flowmeter e-ultrasonic yesimanje angazivumelanisa nezimo ezifana nokushisa, ingcindezi, kanye nezinto zamapayipi (isb., insimbi, i-PVC, noma ithusi) ngesikhathi sangempela, alungise ukuphazamiseka kwesignali okungenzeka futhi agcine ukunemba kuzo zonke izimo zokusebenza ezishintshayo. Isibonelo, ezinhlelweni zokusatshalaliswa kwamanzi, angathola ngisho nokuvuza okuncane noma ukuguquguquka kokugeleza, esiza izinsiza zokusiza ukunciphisa imfucuza yamanzi kanye nokwenza ngcono ukusebenza kwenethiwekhi. Embonini kawoyela negesi, ikhono lazo lokukala uketshezi olunamandla aphezulu ngokunemba liqinisekisa ukukhokhisa okunembile kokuthuthwa kukaphethiloli futhi livimbele ukulahlekelwa yimali engenayo emaphutheni okulinganisa.
Ngaphandle kwezicelo zezimboni, ama-flowmeter e-ultrasonic athola ukuthandwa ezindaweni zokuhlala nezentengiselwano—njengamamitha amanzi ahlakaniphile avumela ukuqapha ukusetshenziswa kude—ngenxa yomklamo wawo omncane kanye nezidingo zokunakekelwa eziphansi. Njengoba ukusimama kuba yinto eza kuqala emhlabeni wonke, ikhono lawo lokulandelela ukusetshenziswa koketshezi ngokusetshenziswa kwamandla okuncane (amaningi asebenza ngamabhethri anamandla aphansi) anezela ekukhangeni kwawo.
Ekuphetheni, ama-flowmeter e-ultrasonic achaza kabusha ukulinganiswa koketshezi ngokuhlanganisa ukulula okungangenisi ukungcola ngokunemba okuphezulu. Ngokususa imikhawulo yamadivayisi endabuko—kusukela esikhathini sokungasebenzi kokufakwa kuya ezingozini zokungcola—awathuthukisi nje kuphela ukusebenza kahle kodwa futhi asekela ukuhambisana, ukonga izindleko, kanye nokusimama kuzo zonke izimboni. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukunemba kwawo kanye nokuguquguquka kwawo kuzokhula kuphela, kuqinise indima yawo njengesisekelo sezinhlelo zanamuhla zokuphathwa koketshezi.
