Thaum ntsuas cov kua dej ntws hauv cov kav dej, cov ntsuas dej ntws ultrasonic lub sijhawm hla mus los yog qhov kev xaiv nrov vim lawv qhov tseeb thiab tsis ua rau mob. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov ntsuas dej ntws no yog txoj kev teeb tsa yooj yim, uas ua rau lawv sib txawv ntawm lwm hom ntsuas dej ntws.
Cov txheej txheem teeb tsa ntawm lub transit time ultrasonic flow meter yog qhov yooj yim heev thiab tuaj yeem ua tiav tau yooj yim. Tsis zoo li cov ntsuas dej ib txwm muaj uas yuav tsum tau txiav rau hauv cov yeeb nkab thiab cov txheej txheem teeb tsa ntau, cov ntsuas dej transit time ultrasonic flow meter tuaj yeem teeb tsa yam tsis cuam tshuam cov kua dej ntws lossis xav tau cov cuab yeej tshwj xeeb.
Qhov yooj yim ntawm cov txheej txheem teeb tsa tuaj yeem yog vim qhov xwm txheej tsis muaj kev cuam tshuam ntawm lub sijhawm hla mus los ntawm ultrasonic flow meters. Cov flow meters no siv cov nthwv dej ultrasonic los ntsuas cov dej ntws yam tsis muaj kev sib cuag ncaj qha nrog cov dej ntws. Qhov no txhais tau tias tsis tas yuav txiav lossis hloov kho cov kav dej, ua rau cov txheej txheem teeb tsa sai thiab tsis muaj teeb meem.
Yuav kom teeb tsa lub transit time ultrasonic flowmeter, thawj kauj ruam yog xaiv qhov chaw tsim nyog ntawm cov yeeb nkab rau kev teeb tsa lub flowmeter. Thaum txiav txim siab qhov chaw teeb tsa lawm, kauj ruam tom ntej yog txuas lub sensor rau sab nraud ntawm cov yeeb nkab. Lub sensor tso tawm thiab tau txais cov teeb liab ultrasonic siv los ntsuas qhov ceev ntawm cov dej ntws. Lub sensor tuaj yeem yooj yim clamped lossis strapped rau ntawm cov yeeb nkab, tshem tawm qhov xav tau cov khoom siv mounting nyuaj.
