Yebo. Ama-flowmeter e-ultrasonic asebenzisa indlela eyodwa avame ukukala ijubane lokugeleza enkabeni yepayipi bese eliguqula libe yijubane lokugeleza elijwayelekile kulo lonke isigaba sepayipi esebenzisa "i-average velocity coefficient." Le coefficient isekelwe ekucabangeni "kokugeleza okuthuthukisiwe ngokugcwele" (lapho ijubane lilandela ukusatshalaliswa kwe-logarithmic). Kodwa-ke, kumapayipi amakhulu, lapho izinga lokugeleza liphansi (ezimweni ze-laminar noma ze-low turbulence ezinenombolo kaReynolds < 2300), ukusatshalaliswa kwejubane kuseduze nesimo se-parabolic. Ngenxa yalokho, iphutha lokuguqulwa kwamamitha e-single-path (kusukela ejubane eliphakathi kuya ejubane eliphakathi) landa kusuka ku-±1% kuya ngaphezu kuka-±3%.
Ngokuphambene nalokho, ama-flowmeter ezindlela eziningi (isb., izindlela ezine noma izindlela ezingu-8) alinganisa ijubane lokugeleza ezindaweni ezahlukene ze-radial futhi abale isilinganiso esilinganisiwe, esingakha kabusha ngokunembile ukusatshalaliswa kwejubane eliwela esigabeni esiphambene. Ngisho nangaphansi kwezimo zokugeleza okuphansi, ukunemba kwawo kungahlala kuzinzile ngaphakathi kuka-±0.5%.
Ngakho-ke, lapho kulinganiswa imidiya yejubane eliphansi (njengakumanethiwekhi okuphakelwa kwamanzi noma amapayipi amakhulu endle) kumapayipi amakhulu, inzuzo yokunemba kwama-flowmeter anezindlela eziningi iba sobala kakhulu njengoba izinga lokugeleza lehla.
