1. Umgaqo wokusebenza kwe-ultrasonic flowmeter
I-Ultrasonic flowmeter sisixhobo sokulinganisa ukuhamba kolwelo esisetyenziswa kakhulu kwimizi-mveliso, sisebenzisa ii-ultrasound sensors ukulinganisa umahluko wesantya kulwelo ukubala ukuhamba kolwelo. Lo mgaqo ulula kakhulu: xa i-ultrasound wave isasazeka kulwelo, ukuba ulwelo luyahamba, ubude be-wave yesandi buya kuba mfutshane kwicala lokuhamba kolwelo kwaye bube bude kwicala elichaseneyo. Ngokulinganisa olu tshintsho, izinga lokuhamba kolwelo linokufunyanwa, kwaye izinga lokuhamba kolwelo lingabalwa ukusuka kwizinga lokuhamba kolwelo kunye nendawo enqamlezileyo yombhobho.
2. Umbhobho wokulinganisa
Nangona kunjalo, kwizicelo ezisebenzayo, ukusebenza kwee-ultrasonic flowmeters kunokuchaphazeleka kukukala. Isikali lulwaleko lwesamente oluvela kumphezulu wangaphakathi wombhobho kwaye lunokubangelwa ngamanzi aqinileyo, amasuntswana aqinileyo axhonyiweyo, okanye ezinye izinto ezingcolileyo. Xa ulwelo ludlula kumbhobho oneesamente, isamente siyaphazamisana nokusasazwa kwamaza esandi, nto leyo ekhokelela ekunciphiseni ukuchaneka kweziphumo zokulinganisa.
Ukubakho kokulinganisa kunokubangela iingxaki ezininzi. Okokuqala, umaleko wesikali uthintela i-sensor ye-ultrasonic ukuba ingafikeleli ngqo kulwelo, nto leyo enciphisa impendulo yesiginali phakathi kweprobe kunye nolwelo. Okwesibini, umaleko wesikali une-acoustic impedance ethile, eya kuchaphazela isantya sokusasazeka kunye nokulahleka kwamandla kwi-ultrasound wave, nto leyo ekhokelela kwiimpazamo zokulinganisa. Ukongeza, umaleko wesikali unokutshintsha imeko yokuhamba kolwelo, nto leyo enyusa inqanaba lokuxinana kolwelo, nto leyo ekhokelela kwiziphumo zokulinganisa ezingachanekanga ngakumbi.
3. Izisombululo kunye namanyathelo okuthintela
Ukuze kusonjululwe ingxaki yokulinganisa echaphazeleka zii-ultrasonic flowmeters, la manyathelo alandelayo angathathwa:
Okokuqala, umbhobho ucocwa rhoqo ukuze kususwe isikali kwaye kugcinwe udonga lwangaphakathi lombhobho luthambile. Oku kunokufezwa kusetyenziswa inani elifanelekileyo leekhemikhali zokucoca okanye izixhobo zokucoca.
Okwesibini, khetha ukusebenzisa i-ultrasonic flowmeter enomsebenzi wokulwa nokukhula. Ezi flowmeter zihlala ziyilelwe ngeengxaki ezinokubakho zokukala engqondweni, kwaye izixhobo ezikhethekileyo zigqunywa kumphezulu wesenzi ukunciphisa amathuba okukala.
Emva koko, kwenziwa umsebenzi wokuhlola nokulungisa rhoqo ukuze kulungiswe naziphi na iingxaki ezinokukhokelela ekulinganisweni ngexesha ukuqinisekisa ukusebenza okuqhelekileyo kwe-ultrasonic flowmeter.
Nangona isiphumo sokusika kwii-flowmeters ze-ultrasonic singenakucinywa ngokupheleleyo, ukuphazamiseka kokusika kwiziphumo zokulinganisa kunokuncitshiswa ngamanyathelo okuthintela afanelekileyo kunye nokugcinwa. Ukusetyenziswa kwee-flowmeters ze-ultrasonic ezichasene nokukhula, kunye nokucoca nokugcinwa rhoqo, kunokuqinisekisa ukuchaneka kwe-flow meter kunye nokuzinza kwexesha elide.
