Ultrasonic flowmeter yog ib hom ntsuas ntws, siv ultrasonic pulse hauv qhov ntws los ntawm ob qho kev qhia ntawm qhov sib txawv ntawm qhov ceev, kom pom qhov ntws ntawm cov kua, yog ib hom tshiab ntawm ultrasonic flow meter tau tsim zoo ntawm kev nqus ntawm ntau qhov zoo ntawm ultrasonic flowmeters hauv tsev thiab txawv teb chaws.
Lub ntsuas dej ntws ultrasonic yog raws li cov ntaub ntawv ntawm qhov ceev ntawm cov dej ntws thaum lub ultrasonic nthwv dej kis mus rau hauv cov kua dej ntws, xws li qhov ceev ntawm cov dej ntws mus tom ntej thiab qhov ntws rov qab vim yog qhov sib tshooj ntawm qhov ceev ntawm cov kua dej. Yog li ntawd, qhov nrawm ntawm cov kua dej tuaj yeem pom los ntawm lub ultrasonic nthwv dej tau txais, uas hloov mus rau qhov nrawm. Lub ntsuas dej ntws ultrasonic yog tsim los ntawm ultrasonic transducer, hluav taws xob Circuit Court thiab cov zaub ntws thiab cov txheej txheem khaws cia.
Qhov chaw teeb tsa xaiv ultrasonic flowmeter yuav tsum xav txog cov hauv qab no: cov yeeb nkab puv, ntws ruaj khov, scaling, kub, siab, cuam tshuam thiab lwm yam.
1, cov yeeb nkab puv: Xaiv ib ntu yeeb nkab puv nrog cov khoom siv kua zoo sib xws, yooj yim rau kev sib kis ultrasonic, xws li ntu yeeb nkab ntsug (kua ntws mus rau saum) lossis ntu yeeb nkab kab rov tav.
2, ntws ruaj khov: qhov kev teeb tsa yuav tsum tau xaiv qhov deb ntawm sab saud ntau dua 10 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab ncaj, thiab sab hauv qab ntau dua 5 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab ncaj yam tsis muaj lub luj tshib, txoj kab uas hla ntawm txoj kab uas hla ntawm cov yeeb nkab ncaj thiab lwm yam, qhov chaw teeb tsa yuav tsum nyob deb ntawm lub valve, twj tso kua mis, lub zog hluav taws xob siab thiab lub tshuab hloov pauv zaus thiab lwm yam kev cuam tshuam.
3, tsis txhob nruab ib lub clamp-hom ultrasonic flowmeter sab nraud hauv lub raj xa dej ntawm qhov chaw siab tshaj plaws lossis qhov chaw tawm dawb ntsug yeeb nkab (kua dej ntws mus rau hauv qab)
4, rau cov kav dej qhib lossis tsis puv, lub ntsuas dej yuav tsum tau teeb tsa rau hauv seem yeeb nkab U-puab.
5, qhov kub thiab siab ntawm qhov chaw teeb tsa yuav tsum nyob hauv qhov ntau uas lub sensor tuaj yeem ua haujlwm.
6, xav txog tag nrho cov xwm txheej ntawm phab ntsa sab hauv ntawm cov yeeb nkab: txawm hais tias kev xaiv cov yeeb nkab tsis yog scaling, yog tias nws tsis tuaj yeem ua tau raws li, qhov scaling tuaj yeem suav hais tias yog lub hauv ob sab hauv kom zoo dua qhov tseeb ntsuas
7, ob lub sensors ntawm sab nraud clamp ultrasonic flowmeter yuav tsum tau ntsia rau hauv kab rov tav ntawm qhov chaw axial ntawm cov kav dej, thiab ntsia rau hauv kab rov tav ntawm qhov chaw axial hauv qhov ntau ntawm ± 45 ° kom tiv thaiv cov yeeb nkab tsis txaus siab, npuas lossis nag lossis daus ntawm sab saud ntawm lub sensor kom cuam tshuam rau qhov ntsuas ib txwm. Yog tias nws tsis tuaj yeem ntsia kab rov tav thiab sib npaug vim qhov txwv ntawm qhov chaw teeb tsa, lub ultrasonic flowmeter tuaj yeem ntsia lub sensor ntsug lossis ntawm lub kaum sab xis nyob rau hauv qhov xwm txheej uas sab saud ntawm lub raj tsis muaj npuas.
