Mfundo yogwiritsira ntchito Doppler
TheDF6100Choyezera mafunde cha series flowmeter chimagwira ntchito potumiza mawu a ultrasound kuchokera ku transducer yake yotumizira, mawuwo adzawonetsedwa ndi ma sonic reflector othandiza omwe amapachikidwa mkati mwa madzi ndikujambulidwa ndi transducer yolandira. Ngati ma sonic reflectors akuyenda mkati mwa njira yotumizira mawu, mafunde a mawu adzawonetsedwa pa frequency shifted (Doppler frequency) kuchokera ku frequency yotumizira. Kusintha kwa mafunde kudzakhudzana mwachindunji ndi liwiro la tinthu toyenda kapena thovu. Kusintha kwa mafunde kumeneku kumatanthauziridwa ndi chida ndikusinthidwa kukhala mayunitsi osiyanasiyana oyezera omwe amagwiritsidwa ntchito ndi ogwiritsa ntchito.
Payenera kukhala tinthu tating'onoting'ono tomwe tingapangitse kuti tinthu tating'onoting'ono tiwonekere bwino - tinthu tating'onoting'ono toposa 100 micron.
Mukayika ma transducer, malo oyikapo ayenera kukhala ndi chitoliro chowongoka chokwanira pamwamba ndi pansi pa mtsinje. Kawirikawiri, chitoliro chakumtunda chimafuna 10D ndipo pansi pa mtsinje chimafuna chitoliro chowongoka cha 5D, pomwe D ndi m'mimba mwake wa chitoliro.
