Intshayelelo
Iimitha zokuhamba kwe-ultrasonicziye zaba zizixhobo zokulinganisa ukuhamba kwamanzi ezingangenisi mandla kwiipayipi zolwelo kunye negesi kulo lonke unikezelo lwamanzi, iikhemikhali, amandla kunye namashishini okufudumeza. Phakathi kwazo zonke iintlobo, iimitha ze-ultrasonic ezinendlela enye ziyafikeleleka kodwa zinqongophele ngokuchanekileyo, ngelixa iimitha ze-ultrasonic ezineendlela ezimbini (ezineendlela ezimbini) zibonakala ngokuchaneka okuphezulu kokulinganisa kunye nozinzo olungcono phantsi kweemeko zokusebenza ezinzima. Ukuchaneka okugqwesileyo kweemitha ze-ultrasonic ezineendlela ezimbini kuvela kuyilo lwesignali ye-acoustic olulungisiweyo, imbuyekezo yempazamo yentsimi yokuhamba, uyilo lokulwa nokuphazamiseka kunye nee-algorithms zokubala imiqondiso eziphambili. Eli nqaku lichaza izizathu zobugcisa eziphambili emva kokuchaneka kwayo okuphezulu kwaye lithelekisa ukusebenza kwayo nezixhobo zendlela enye kwiindawo zokwenyani zepayipi.
1. Umgaqo-siseko wokulinganisa ii-Ultrasonic Flowmeters
Iimitha zokuhamba kwe-ultrasonicyamkela indlela yokwahluka kwexesha lokuhamba njengomgaqo oyintloko wokulinganisa. Iitransmitter kunye neereceiver ezifakwe eludongeni lombhobho zithumela iipulses ze-ultrasonic kuyo yonke ipayipi. Xa ulwelo lungaguquki, amaxesha okusasazeka phambili nangasemva kwamaza esandi ayalingana. Xa ulwelo okanye igesi ihamba, amaza esandi ahamba ngezantsi ahamba ngokukhawuleza, kwaye amaza esandi anyukayo ancitshiswa kukumelana nolwelo. Inkqubo ibala isantya sokuhamba esiphakathi ngokusekelwe kumahluko wexesha kwaye ibala ngakumbi isantya sokuhamba kwevolumu.
Imitha yendlela enye ifaka isibini esinye see-transducers ecaleni kwe-chord enye ngaphakathi kwipayipi. Ibamba kuphela isantya sokuhamba kuloo ndlela inye ye-acoustic, engenakubonisa ukusasazwa kwesantya esipheleleyo kulo lonke icandelo elinqamlezileyo lepayipi. Ngokwahlukileyo koko, ii-flowmeters ze-ultrasonic ezineendlela ezimbini zisebenzisa ii-acoustic chords ezimbini ezizimeleyo kwiindawo ezahlukeneyo zangaphakathi kwepayipi, ziqokelela idatha yesantya kwiileya ezimbini ezahlukeneyo zokuhamba ngaxeshanye, zibeka isiseko sehardware ukuze zichaneke kakhulu.
2. Iindlela ezimbini zisusa iimpazamo ezibangelwa kukusasazwa kwesantya esingalinganiyo
Kwiimeko ezifanelekileyo zelebhu, ulwelo ngaphakathi kombhobho othe tye ophuhliswe ngokupheleleyo lwenza intsimi yesantya esilinganayo separabolic: isantya esiphezulu sokuhamba sivela kwiziko lombhobho, kwaye isantya siyehla kancinci kufutshane nodonga lombhobho. Iimitha zendlela enye zihlala zicwangcisa umgca we-acoustic kwindawo ephakathi ukuze zenze isampuli yesantya esiphezulu, esisebenza kakuhle phantsi kokuhamba kwe-laminar okugqibeleleyo.
Nangona kunjalo, imibhobho yokwenyani yemizi-mveliso ayisoloko igcina imeko yokuhamba kakuhle. Iingqiniba, iivalvu, izixhobo zokunciphisa, iimpompo kunye nemibhobho yamasebe zenza amasimi okuhamba agqwethekileyo, angalinganiyo. I-chord enye yokulinganisa inokudlula kwindawo yokuhamba ngokukhawuleza okungaqhelekanga okanye kancinci, nto leyo ekhokelela ekuphambukeni okukhulu kokulinganisa okucwangcisiweyo.
Ii-flowmeter ze-ultrasonic ezineendlela ezimbini zisombulula esi siphene ngokusisiseko. Iindlela ezimbini ze-acoustic zicwangciswe ngendlela enqamlezileyo okanye enqamlezileyo, zigubungela iindawo eziphezulu, ezisezantsi, ezisekhohlo nezisekunene zecandelo elinqamlezileyo lombhobho. Isilawuli silinganisa amaxabiso esantya aqokelelwe kwiindlela ezimbini ezizimeleyo ukuze sinciphise isantya sokuhamba esingaqhelekanga sendawo. Nokuba kukho ukuphambuka okukhulu kokuhamba okubangelwa ziinxalenye zepayipi ezimfutshane ezithe tye, idatha edibeneyo evela kwiindlela ezimbini inokubuyisela isantya sokuhamba esiqhelekileyo secandelo elinqamlezileyo, inciphise kakhulu iimpazamo zokulinganisa ezibangelwa yiprofayili yokuhamba.
3. Amandla Okubuyisela Amandla Okungaguquguqukiyo, Ukungcangcazela kunye Nokuphazamiseka Okuphakathi
Ukungcangcazela kwemibhobho, amaqamza amancinci, amasuntswana axhonyiweyo kunye nokuguquguquka kobushushu konke kuphazamisana nokudluliselwa kwesignali ye-ultrasonic, okubangela ukujija kwesignali kwangoko kunye neempazamo zokulinganisa ngokungacwangciswanga. Iimitha zendlela enye zixhomekeke kwiseti enye yemiqondiso ye-acoustic; xa indlela ivaliwe okanye incitshisiwe ngamaqamza, isiphumo sokulinganisa sonke siyaphambuka kakhulu.
Kwizixhobo zeendlela ezimbini, ukuphazamiseka akusoloko kuchaphazela ii-chords ezimbini ze-acoustic ngexesha elinye. Ukuba enye indlela ifumana ukuncitshiswa kwesignali kwiibhamuza zomoya okanye i-sediment, indlela yesibini isenokukhupha idatha yesantya esizinzileyo. I-microprocessor eyakhelwe ngaphakathi ihlola imiqondiso engaqhelekanga ngokuzenzekelayo, ilinganisa idatha esebenzayo kuzo zombini iitshaneli kwaye ihluze ingxolo engacwangciswanga. Oku kuphindaphindwa kweendlela ezimbini kuthintela ukuguquguquka kokufundwa kokuhamba ngokukhawuleza kwaye kuphucula ukuphindaphindwa kokulinganisa ixesha elide, uphawu oluphambili lokuchaneka kokulinganisa okuphezulu.
4. Ukuxhomekeka Okuncitshisiweyo Kwicandelo Lemibhobho Emide Ethe Tye
Konkeii-flowmeters ze-ultrasoniczifuna iinxalenye zemibhobho ezithe tye phezulu nasezantsi ukuze zenze amasimi okuhamba azinzileyo. Iimitha zendlela enye zifuna ubude bemibhobho ethe tye kakhulu ukuze kuncitshiswe ukugqwetheka kokuhamba, nto leyo ebangela imida emikhulu yokufakela kwiindawo zoshishino ezincinci ezineevalvu ezixineneyo kunye neengqiniba. Ukuba indawo yokufaka ayihlangabezani neemfuno zemibhobho ethe tye, ukuchaneka kuya kwehla kakhulu.
Ngenxa yokulungiswa kwendlela yokuhamba kwendle, ii-dual-path ultrasonic flowmeters zinyamezela amacandelo amafutshane eepayipi ezithe tye. Ii-chords ezimbini zokulinganisa zilungelelanisa ukuhamba okungalinganiyo, zinciphisa isiphumo sokukhulisa iimpazamo sobude obungaphelelanga bepayipi ethe tye. Kubunjineli obusebenzayo, ii-dual-path meters zinokugcina ukuchaneka kweklasi 0.5 okanye iklasi 1.0 phantsi kwendawo encinci yokufaka, ngelixa ii-single-path meters zihlala ziwohloka ziye kwiklasi 2.0 okanye zibe mbi phantsi kweemeko ezifanayo.
5. I-Algorithm Yokusebenza Ehambelanayo Yezitishi Ezimbini Eziphambili
Uyilo lwezixhobo zodwa alunakuqinisekisa ukuchaneka okuphezulu ngaphandle kwesoftware yokubala ehambelanayo.ii-flowmeters ze-ultrasonicyamkela iteknoloji yokulinganisa iisampulu ezihambelanayo: amaqela amabini ee-transducers athumela kwaye afumane imiqondiso ye-ultrasonic ngexesha elinye. Iprosesa ibala ngokulinganayo umahluko wexesha lokuhamba kweendlela zombini, isuse iimpazamo zexesha phakathi kwemijikelo eyahlukeneyo yokulinganisa, kwaye isebenzise ii-algorithms eziphakathi ezilinganisiweyo ukuhlaziya isantya sokuhamba kwecandelo elinqamlezileyo.
Ezinye iimodeli eziphuculweyo zongeza iimodyuli zokuhlawula ubushushu kunye nesantya sesandi kwitshaneli nganye ngokuzimeleyo. Zilinganisa isantya sokusasazeka kwamaza esandi ngokwahlukeneyo kwiindlela ezimbini ze-acoustic ukulwa nokusasazwa kobushushu obuphakathi okungalinganiyo, zinciphisa ngakumbi iimpazamo zenkqubo kwaye zenze ukuchaneka okuphezulu okuzinzileyo kumanqanaba obushushu abanzi kunye nokuhamba kwamanzi.
6. Uthelekiso Lokusebenza Ngokuchaneka Okusebenzayo
Phantsi kweemeko eziqhelekileyo zokuhamba okuzinzileyo kwelabhoratri, indlela enyeiimitha ze-ultrasonicngokuqhelekileyo zifikelela kwinqanaba lokuchaneka kwe-±1.0% ~ ±2.0% yokufunda. Iimveliso zeendlela ezimbini zifikelela ngokuzinzileyo ukuchaneka kwe-±0.5% ~ ±1.0%. Kwiimeko ezintsonkothileyo zokuhamba kwamanzi kwindawo enezingqiniba kunye neevalvu, impazamo yokulinganisa indlela enye inokunyuka ngaphezu kwe-±3%, ngelixa iimitha zeendlela ezimbini zilawula impazamo iyonke ngaphakathi kwe-±1.0%. Olu lwazi luphezulu oluzinzileyo lwenza iimitha ze-ultrasonic zeendlela ezimbini zilungele ukulinganisa urhwebo, ukulinganisa ibhalansi yamandla kunye neemeko zokuhlala kwemithombo yamanzi ezisemgangathweni ophezulu apho ukuchaneka kokulinganisa kuchaphazela ngokuthe ngqo iingenelo zoqoqosho.
Isiphelo
Ukuchaneka okuphezulu kwendlela ezimbiniii-flowmeters ze-ultrasonicyinzuzo edibeneyo yoyilo lwe-acoustic oluphindwe kabini, imbuyekezo yokuphambuka kwentsimi yokuhamba, uyilo oluchasene nokuphazamiseka okungafunekiyo, imfuneko yepayipi ethe tye esezantsi kunye ne-algorithms yokusebenza kwe-dual-channel ehambelanayo. Ngokungafaniyo neemitha zendlela enye ezinqunyelwe kwiimeko ezilula nezifanelekileyo zepayipi, izixhobo zendlela ezimbini zithintela ngokufanelekileyo izinto ezahlukeneyo zokuphazamiseka kwindawo kwaye zibuyisela isantya sokuhamba esiqhelekileyo kulo lonke icandelo lepayipi. Njengoko amashishini ephakamisa imigangatho engqongqo yokulungiswa korhwebo kunye nokubeka esweni ulwelo ngokuchanekileyo, ii-dual-path ultrasonic flowmeters ziba sisisombululo sokulinganisa esichanekileyo esikhethwayo sokulinganisa ukuhamba kolwelo kunye negesi kwiinkqubo zepayipi zemizi-mveliso ezintsonkothileyo.
