Nyob rau hauv xyoo tas los no, ntau yam tshiabhom ultrasonic flowmetertau tshwm sim nyob rau hauv kev ua lag luam, xws li digital ultrasonic flow meters siv digital circuits thiab integrated ultrasonic flow meters (sib txuas lub sensor thiab converter rau hauv ib qho). Tau ntsib nrog ntau yam ntawm ultrasonic flowmeter, cov neeg siv yuav tsum xaiv cov qauv tsim nyog raws li lawv qhov xwm txheej tiag tiag thiab ntsuas qhov xav tau. Tsab ntawv xov xwm no yuav qhia txog qhov sib txawv ntawm kev xaiv tsib hom ultrasonic flow meter nyob rau hauv kev ua lag luam thiab pom zoo ob peb ultrasonic flow meter daws teeb meem los ntawm Tuam Tshoj los pab txhawb engineers xaiv thiab tsim cov ntaub ntawv.
Tsib hom ultrasonic flow meters ntawm kev ua lag luam
Doppler Ultrasonic Flow Meter
Hom ntsuas no tsuas tuaj yeem ntsuas cov kua dej uas muaj qhov tsim nyog ntawm cov khoom lossis cov npuas uas tuaj yeem cuam tshuam cov cim ultrasonic, xws li cov khoom siv hluav taws xob hauv lub Hoobkas, cov dej khib nyiab tsis kho, thiab cov txheej txheem dej nrog cov ntsiab lus tsis huv. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nws muaj cov cai nruj rau qhov ntsuas nruab nrab; nws tsis tuaj yeem yog dej huv, thiab cov ntsiab lus impurity yuav tsum ruaj khov rau kev ntsuas ib txwm. Tsis tas li ntawd, qhov kev ua tau zoo thiab kev xav tau rau qhov ntsuas nruab nrab sib txawv ntawm cov tuam ntxhab sib txawv. Xaiv hom ultrasonic flow meter yuav tsum muaj kev nkag siab zoo ntawm qhov ntsuas nruab nrab, nrog rau kev ua tau zoo, qhov tseeb, thiab cov cai ntawm kev xaiv ultrasonic flow meter.
Portable Ultrasonic Flow Meter
Hom no yog tsim rau kev ntsuas ib ntus, feem ntau yog siv los ntsuas qhov kev khiav hauj lwm ntawm lwm cov ntsuas ntws ntawm cov kav dej, ua cov ntsuas dej sib npaug hauv ib cheeb tsam, thiab xyuas qhov ntsuas tam sim no hauv cov kav dej. Rau cov hom phiaj no yam tsis muaj kev txhim kho, lub ntsuas hluav taws xob portable ultrasonic yog ob qho yooj yim thiab kev lag luam.
Lub sij hawm- ntawm- Davhlau Ultrasonic Flow Meter
Tam sim no, feem ntau tsim thiab siv hom yog lub sij hawm - ntawm - dav hlau ultrasonic flow meter. Nws yog tsuas yog siv los ntsuas tus nqi ntws ntawm cov kua dej huv thiab siv dav hauv cov tuam txhab muab dej thiab kev siv dej hauv kev lag luam. Tsis tas li ntawd, nws tseem tuaj yeem ntsuas tus nqi ntws ntawm homogeneous kua nrog cov ntsiab lus impurity tsawg (cov ntsiab lus impurity tsawg dua 10g / L thiab particle loj tsawg dua 1 hli), xws li dej phwj tuaj, nrog qhov tseeb ntawm ± 1.5%. Cov ntawv thov siv tau qhia tias siv lub sijhawm- sib txawv ultrasonic flow meter tuaj yeem ua tiav cov txiaj ntsig zoo hauv kev ntsuas cov kua dej sib xws.
Hauv - kab Ultrasonic Flow Meter
Muab qhov tseeb tshaj plaws, ncav cuag ± 0.5%, thiab tsis txwv los ntawm cov khoom siv yeeb nkab lossis hauv ob sab phlu, ua rau nws haum rau cov ntawv thov uas yuav tsum tau ntsuas qhov ntsuas siab. Txawm li cas los xij, raws li txoj kab uas hla ntawm cov yeeb nkab nce, tus nqi kuj nce ntxiv. Feem ntau, me me - mus rau - nruab nrab txoj kab uas hla hauv - kab ultrasonic flow meters yog kev lag luam ntau dua.
Tsau Ultrasonic Flow Meter
Yog tias muaj qhov chaw tsim khoom txaus, siv qhov kev hloov pauv hloov pauv hloov mus rau sab nraud transducer tag nrho tshem tawm cov yeeb nkab hauv ob sab phlu, scaling, thiab cov yeeb nkab phab ntsa ntawm cov teeb liab ultrasonic attenuation, uas ua rau kev ntsuas siab dua thiab txo kev txij nkawm. Tsis tas li ntawd, vim tias cov transducers ntxig tuaj yeem ntsia tau yam tsis muaj kev cuam tshuam kev ntws, lawv daim ntawv thov tau nce zuj zus.
