2.1 Phetoho ea ho ba le ho hlaka le lebelo la molumo
Ha mocheso oa mokelikeli o theohela ka tlase ho moeli o ka tlase oa sebaka se khothaletsoang, viscosity ea mokelikeli hangata ea eketseha. Mohlala, tabeng ea oli e itseng, ha mocheso o fokotseha, oli e ba teteaneng, e leng se ka sitisang ho ata ha maqhubu a ultrasound ka har'a mokelikeli. Ho feta moo, lebelo la molumo mokelikeling lea fokotseha ka ho theoha ha mocheso. Kaha li-flowmeter tsa ultrasound li itšetlehile ka tekanyo ea nako - ea - ho fofa kapa phetoho ea Doppler ea maqhubu a ultrasound, liphetoho tsena lebelong la molumo li ka lebisa litekanyong tse sa nepahalang tsa phallo.

Maemong a mocheso o phahameng, kaholimo ho moeli o kaholimo oa sebaka se boletsoeng sa ts'ebetso, ts'ebetso ea li-sensor tsa ultrasonic e ka fokotseha. Lisebelisoa tsa piezoelectric tse sebelisoang ho li-transducer tsa ultrasonic li ka 'na tsa ba le phokotso ea coefficient ea tsona ea piezoelectric ha mocheso o ntse o phahama. Phokotso ena e bolela hore li-transducer ha li sebetse hantle haholo ho fetoleng matla a motlakase hore e be maqhubu a ultrasound le ka tsela e fapaneng. Ka lebaka leo, matla a lets'oao a amoheloang ke moamoheli oa flowmeter a ka fokola, a lebisang liphosong tsa tekanyo ea phallo.
3.2 Liphetoho tsa Lik'hemik'hale le tsa 'Mele Metsing
Metsi a mocheso o phahameng a ka boela a feta diphetohong tsa dikhemikhale kapa tsa mmele tse ka amang tekanyo ya phallo. Mohlala, ditshebetsong tse ding tsa dikhemikhale, dithempereichara tse phahameng di ka etsa hore mokelikeli o bole kapa o arabele ka thepa e kolobisitsweng ya flowmeter.

4. Puseletso ea Mocheso
Ho sebetsana le mathata a bakoang ke diphetoho tsa mocheso wa metsi, ba bangatali-flowmeter tsa ultrasoundli na le mekhoa ea puseletso ea mocheso. Mekhoa ena e ka ba ea hardware kapa ea software. Puseletso ea mocheso e thehiloeng ho Hardware hangata e kenyelletsa ho sebelisa li-sensor tse ling tsa mocheso tse behiloeng haufi le karolo ea tekanyo ea ultrasonic flowmeter. Li-sensor tsena tsa mocheso li lula li beha leihlo mocheso oa metsi, 'me lisebelisoa tsa elektroniki tsa flowmeter li sebelisa tlhahisoleseling ena ho fetola li-algorithms tsa tekanyo. Puseletso e thehiloeng ho Software, ka lehlakoreng le leng, e itšetlehile ka li-algorithms tse hlophisitsoeng esale pele tse nahanang ka kamano e tsejoang pakeng tsa mocheso, lebelo la molumo le sekhahla sa phallo. Ka ho sebelisa li-algorithms tsena, flowmeter e ka lokisa liphoso tse bakoang ke mocheso le ho fana ka litekanyo tse nepahetseng haholoanyane tsa phallo ho pholletsa le mocheso o pharaletseng.
