Ii-Transit - Izinzwa zexesha
Iisensa zexesha zokuhamba zisebenza ngokusekelwe kumgaqo wokulinganisa umahluko wexesha lamaza e-ultrasonic ukuhamba kwicala lokuhamba kunye necala lokuhamba. Ezi sensa zihlala zinezibini zee-transducers ze-ultrasonic. I-transducer enye isebenza njengomthumeli, ikhupha amaza e-ultrasonic kulwelo, ngelixa enye isebenza njengommkeli.
Xa ulwelo luhamba, amaza e-ultrasonic ahamba ngezantsi aza kufikelela kwi-receiver ngexesha elifutshane xa kuthelekiswa nalawo ahamba phezulu. Ngokulinganisa ngokuchanekileyo lo mahluko wexesha, isantya sokuhamba kolwelo singabalwa. Ii-transit-time sensors zichanekile kakhulu kwaye zifanelekile ukulinganisa ukuhamba kolwelo olucocekileyo nolufanayo. Zihlala zisetyenziswa kwiindawo apho kufuneka khona ukulinganisa ukuhamba okuchanekileyo, njengakwiindawo zokucubungula iikhemikhali zokulinganisa ukuhamba kolwelo olucocekileyo okanye kwezinye iindawo zonyango lwamanzi.
Isiphumo seDoppler- Izinzwa ezisekelwe
Isiphumo seDoppler - ii-sensors ezisekelwe kwi-Doppler zixhomekeke kwisiphumo seDoppler, esenzeka xa kukho intshukumo phakathi komthombo we-ultrasonic (i-transmitter), ulwelo, kunye ne-receiver. Kwi-Doppler ultrasonic flow meter, i-ultrasonic transducer ikhupha amaza e-ultrasonic kulwelo. Ukuba kukho amasuntswana okanye amaqamza kulwelo, amaza e-ultrasonic aya kusasazeka zezi zinto zihambayo. Isantya samaza asasazekileyo afunyenwe yi-transducer siya kwahluka kwisantya esikhutshwayo.
Olu tshintsho lwefrikhwensi luhambelana nesantya seengqayi okanye amaqamza kulwelo, kwaye ke ngoko, isantya sokuhamba kolwelo sinokumiselwa. Izinzwa ezisekwe kwi-Doppler effect ziluncedo kakhulu ekulinganiseni ukuhamba kolwelo oluqulethe iingqayi okanye amaqamza axhonyiweyo, njengamanzi amdaka kwizityalo zonyango lwamanzi amdaka, i-pulp kunye ne-slurry yeshishini lephepha, okanye imixube yamanzi eoyile kwishishini lepetroleum.
Ukongeza kwezi ntlobo zimbini ziphambili, kukwakho nezinye izinzwa ezixutyiweyo ezidibanisa iimpawu zokuhamba - ixesha kunyeIsiphumo seDoppler- iisensa ezisekelwe kuzo. Ezi sensa ze-hybrid zijolise ekusebenziseni amandla azo zombini iintlobo zeesensa, zibonelela ngemilinganiselo yokuhamba echanekileyo nethembekileyo kwiimeko ezinzima zolwelo.
Ukuqukumbela, ukukhethwa kodidi lwesenzi kwiImitha yokuhamba kwe-Doppler ultrasonickuxhomekeke kuhlobo lolwelo olulinganiswayo. Iisensa zexesha lokuhamba zilungele ulwelo olucocekileyo, ngelixa iisensa ezisekelwe kwi-Doppler effect zilungele ulwelo olunento exhonyiweyo. Ukuqonda ezi ndidi zesensa kubalulekile kwiinjineli kunye nabaqhubi ukuba bakhethe imitha yokuhamba kwe-Doppler efanelekileyo kakhulu kwizicelo zabo ezithile, ukuqinisekisa ukulinganiswa kokuhamba ngokuchanekileyo nangokufanelekileyo.
