Icala lokufakelwa kwe-ultrasonic flowmeter linefuthe kumlinganiselo.

Icala lokufakelwa kwe-ultrasonic flowmeter linefuthe ekulinganisweni. I-ultrasonic flowmeter ibala isantya sokuhamba ngokulinganisa ixesha lokusasazeka kwe-ultrasonic wave kulwelo. Isantya sokusasazeka kwe-ultrasonic wave kulwelo siya kuchatshazelwa yindlela yokuhamba kolwelo, kwaye indlela yokufaka ye-sensor iya kuchaphazela i-Angle yokudluliselwa kwe-ultrasonic wave kunye nokwamkelwa kwayo, ngaloo ndlela ichaphazela iziphumo zokulinganisa. Umzekelo, kumahluko wexesha i-ultrasonic flowmeter, isignali ye-ultrasonic ihamba ngamaxesha ahlukeneyo kwicala elingaphambili nelingasemva, kwaye izinga lokuhamba kolwelo lingabalwa ngokulinganisa umahluko wexesha ezimbini. Ukuba icala lokufakela alichanekanga, umgwebo we-upstream kunye ne-upstream unokuba ungalunganga, nto leyo eya kuchaphazela isiphumo sokubala sesantya sokuhamba. Okwesibini, impembelelo yeendlela ezahlukeneyo zokufakela Ukufakwa ngokuthe nkqo: xa i-ultrasonic flow meter ifakelwe ngokuthe nkqo, kuyimfuneko ukuqinisekisa ukuba umphezulu wokukhupha we-sensor umi nkqo kwicala lokuhamba kolwelo. Ukuba ukufakwa kwe-Angle deviation inkulu, kuya kuchaphazela indlela yokusasazeka yesignali ye-ultrasonic, okubangela impazamo yokulinganisa eyonyukileyo. Umzekelo, xa ufaka i-flowmeter yangaphandle ebotshelelweyo ye-ultrasonic kumbhobho othe tye, ukuba i-Angle yofakelo ye-sensor iphambuka kwicala elithe nkqo ngaphaya koluhlu oluthile, iziphumo zokulinganisa zinokugoba kakhulu. Ukufakela ngokuthe nkqo: Xa ufaka ngokuthe nkqo, icala lokuhamba kolwelo linempembelelo enkulu ekusasazekeni kwe-ultrasound wave. Ngokubanzi, kulwelo oluhamba phezulu, isantya sokusasazeka kwamaza e-ultrasonic siya kuncitshiswa ngumxhuzulane; Kulwelo oluhamba phantsi, isantya se-ultrasonic wave siya kwanda. Umzekelo, xa ufaka ii-flowmeter ze-ultrasonic kwimibhobho ethe nkqo ukulinganisa ukuhamba kolwelo, kuyimfuneko ukuqwalasela icala lokuhamba kolwelo kunye nempembelelo yomxhuzulane kwiziphumo zokulinganisa, kwaye wenze imbuyekezo ehambelanayo. Okwesithathu, ukubaluleka kwendlela yokufakela echanekileyo ukuqinisekisa ukuchaneka kokulinganisa: ukufakwa kwe-flowmeter ye-ultrasonic kwicala lokufakela elichanekileyo kunokuqinisekisa ukuba indlela yokudlulisela yesignali ye-ultrasonic ihlangabezana neemfuno zoyilo, ngaloo ndlela kuphucula ukuchaneka kokulinganisa. Ingakumbi kwiimfuno zokulinganisa ngokuchanekileyo, icala lokufaka elichanekileyo libalulekile. Umzekelo, kwezinye izilinganiso zorhwebo, iimfuno zokuchaneka kokulinganisa ziphezulu, kwaye ukufakelwa kufuneka kwenziwe ngokuhambelana neemfuno zemiyalelo yokufakela ukuqinisekisa ukuchaneka kweziphumo zokulinganisa. Ziphephe iimpazamo zokulinganisa: Icala elingalunganga lokufaka linokukhokelela kwiimpazamo zokulinganisa ezingakumbi kwaye lenze imitha yokuhamba ingasebenzi kakuhle. Umzekelo, ukuba umphezulu womthumeli we-sensor ufakwe ngokuhambelana necala lokuhamba kolwelo, isignali ye-ultrasonic esebenzayo isenokungafunyanwa kwaye ukulinganiswa kokuhamba kusenokungenzeki. Yandisa ubomi bemitha yokuhamba: Icala elichanekileyo lokufaka linokunciphisa impembelelo yolwelo lwemitha yokuhamba kunye nokungcangcazela, ngaloo ndlela landisa ubomi benkonzo yemitha yokuhamba. Umzekelo, kwimeko yokungazinzi kokuhamba kolwelo okanye ukubetha kwephayiphi, icala elichanekileyo lokufaka linokunciphisa impembelelo yemitha yokuhamba kwaye linciphise umngcipheko wokonakala. Ngamafutshane, icala lokufaka lemitha yokuhamba kwe-ultrasonic linempembelelo ebalulekileyo kumlinganiselo. Ekufakweni kwexesha lokuhamba kwe-ultrasonic, kuyimfuneko ukukhetha icala elichanekileyo lokufaka ngokuhambelana neemfuno zemiyalelo yokufakela ukuqinisekisa ukuchaneka kweziphumo zokulinganisa kunye nokusebenza okuqhelekileyo kwemitha yokuhamba.
