Molao-motheo oa ts'ebetso ea Doppler
TheDF6100series flowmeter e sebetsa ka ho fetisa molumo oa ultrasonic ho tloha ho transducer ea eona e fetisang, molumo o tla bontšoa ke li-reflectors tse molemo tsa sonic tse emisitsoeng ka har'a mokelikeli 'me li ngotsoe ke transducer e amohelang.Haeba li-reflectors tsa sonic li ntse li tsamaea ka har'a tsela ea phetisetso ea molumo, maqhubu a molumo a tla bontšoa ka lebelo le fetotsoeng (Doppler frequency) ho tloha maqhubu a fetisoang.Ho fetoha ha maqhubu ho tla amana ka kotloloho le lebelo la phatsa e tsamaeang kapa bubble.Phetoho ena ea maqhubu e hlalosoa ke sesebelisoa 'me e fetoleloa ho likarolo tse fapaneng tse hlalositsoeng ke basebelisi.
E tlameha ebe ho na le likaroloana tse kholo ho lekana ho etsa hore ho be le ponahalo ea longitudinal - likaroloana tse kholo ho feta 100 micron.
Ha u kenya li-transducers, sebaka sa ho kenya se tlameha ho ba le bolelele bo lekaneng ba pipe e otlolohileng holimo le tlaase.Ka tloaelo, ho ea holimo ho hloka 10D le ho theoha ho hloka bolelele ba phala e otlolohileng ea 5D, moo D e leng bophara ba pipe.
