Vim li cas lub flowmeter qhia cov ntawv nyeem tsis ruaj khov thiab hloov pauv, thiab yuav daws qhov teeb meem no li cas?

Qhov no tej zaum yuav yog vim muaj kev co ntau dhau ntawm cov yeeb nkab uas lub ultrasonic flow sensor tau teeb tsa, lossis muaj cov khoom siv hloov pauv dej (piv txwv li, lub flowmeter tau teeb tsa rau hauv qab ntawm cov twj tso kua dej, cov twj tso kua dej, lossis cov qhov). Txoj kev daws teeb meem yog rov nruab lub flow sensor kom deb ntawm cov chaw co lossis txav nws mus rau sab saud ntawm cov khoom siv hloov pauv dej. Qhov no ua kom muaj qhov chaw ntsuas ruaj khov thiab txo qhov cuam tshuam ntawm cov yam sab nraud ntawm cov teeb liab ultrasonic, yog li ua kom cov nyeem ntawv ruaj khov.
