Ultrasonic flowmeters feem ntau muaj cov khoom tseem ceeb hauv qab no:

1 Lub Tshuab Xa Xov (Transducer): Lub tshuab xa xov yog ib qho ntawm cov khoom tseem ceeb ntawm lub ntsuas dej ultrasonic, uas yog lub luag haujlwm rau kev tsim cov suab ultrasonic thiab xa lawv mus rau cov kua dej. Cov suab no feem ntau raug xa mus rau ntawm lub sijhawm teem tseg.

2 Lub Tshuab Txais (Transducer): Lub tshuab txais kuj yog ib qho ntawm cov khoom tseem ceeb rau kev txais cov teeb liab ultrasonic uas cuam tshuam rov qab los ntawm cov kua dej. Lub tshuab txais hloov cov teeb liab tau txais mus rau hauv cov teeb liab hluav taws xob rau kev ua tiav tom qab.

3. Chav Ua Haujlwm Teeb Liab: Chav no yog siv los ntsuas lub sijhawm nthuav dav ntawm lub ultrasonic nthwv dej thiab ua cov teeb liab tau txais. Nws feem ntau suav nrog cov khoom xws li lub voj voog moos, lub txee, thiab lub processor teeb liab digital.

4. Cov Yeeb Nkab Nqus: Cov yeeb nkab kua yog ib txoj kab uas ntsuas qhov ntws ntawm cov kua, thiab lub ultrasonic pulse yog propagated los ntawm cov channel no.

5. Kev Sib Dhos Sensor Mounting: Lub cuab yeej no yog siv los mount lub transmitter thiab receiver rau ntawm cov yeeb nkab kua kom ntseeg tau tias lub ultrasonic nthwv dej tuaj yeem xa mus tau zoo thiab tau txais kom raug.
