Portable ultrasonic flowmeter yog ib hom ultrasonic flowmeter.Ultrasonic flowmeter yog ib qho flowmeter uas ua haujlwm nyob rau hauv ultrasonic lub sij hawm sib txawv thiab Doppler hom, vim hais tias qhov txaus ntsuas qhov tseeb ntawm lub ultrasonic flowmeter yog yuav luag ywj siab ntawm qhov kub thiab txias ntawm qhov txaus ntsuas.Viscosity, ntom thiab lwm yam tsis, thiab tuaj yeem ua rau cov khoom siv tsis sib cuag thiab txav tau yooj yim, yog li nws tuaj yeem daws tau lwm yam nyuaj rau kev ntsuas kev ntsuas dej xws li muaj zog corrosive, tsis yog-conductive, radioactive thiab flammable thiab explosive media.Hom twj paj nruag.Nws qhov kev ua tau zoo sib txawv tau yeej qhov kev nyiam ntawm cov neeg siv.
1. Kev cuam tshuam ntawm kev teeb tsa ib puag ncig, txuas txuas thiab teeb liab kab ntawm kev ntsuas
Portable ultrasonic flowmeters feem ntau siv ntau lub mem tes, broadband signals, nrog rau qee lub peev xwm los tiv thaiv electromagnetic cuam tshuam.Txawm li cas los xij, muaj ntau zaus ntawm qhov chaw teeb tsa, tshwj xeeb tshaj yog tias qhov kev hloov pauv zaus cuam tshuam tsis zoo tag nrho.Lub teeb liab kab ntawm lub transducer tsis yooj yim kom ntev dhau, thiab ib coaxial cable ntawm cov impedance tshwj xeeb yuav tsum tau siv, thiab yuav tsum tsis muaj kev sib koom ua ke ntawm qhov kawg thiab hauv nruab nrab.Tus neeg sawv cev ultrasonic coupling yuav tsum siv kom deb li deb tau nrog lub suab zoo thiab tsis yooj yim rau kev sib xyaw nrog cov khoom siv roj, xws li iav dej, Vaseline, thiab lwm yam.
2, ultrasonic flowmeter tsis raug calibrated
Txhua lub flowmeter yuav tsum tau kuaj xyuas lossis ntsuas ua ntej siv, thiab cov ntsuas ntsuas ultrasonic portable yog qhov tseem ceeb rau lub sijhawm no.Vim hais tias lub portable ultrasonic flow meter yog feem ntau nruab nrog ntau yam ntawm cov transducers, haum rau txawv cov yeeb nkab txoj kab uas hla, txhua txheej ntawm transducer thiab ua ke ntawm tus tswv tsev yog theoretically ib txheej ntawm flowmeter.Yog li ntawd, yog hais tias tsuas yog ib tug me me transducer yog siv los calibrate los yog calibrate ib portable ultrasonic flowmeter ntawm ib tug ndlwg standard ntaus ntawv nrog ib tug me me txoj kab uas hla, ces yog hais tias ib tug loj transducer yog siv los ntsuas qhov txaus thaum siv, nws yog sib npaug rau siv ib tug unverified los yog calibrated flowmeter nrog ntsuas qhov tseeb uas tsis tuaj yeem lav.Txoj kev raug yog raws li tus neeg siv tus kheej siv raws li kev siv, thiab lub portable ultrasonic flowmeter yuav tsum tau soj ntsuam los yog calibrated ntawm ntau cov kav dej ntawm cov qauv ntws nrog tib txoj kab uas hla lossis ze rau cov yeeb nkab siv.Qhov tsawg kawg nkaus, nws yog ib qho tsim nyog los xyuas kom meej tias txhua pawg ntawm cov sensors teeb tsa nrog lub ntsuas ntsuas yuav tsum tau ntsuas.Daim ntawv pov thawj ' meter ' los yog daim ntawv pov thawj calibration yuav muab lub ntsuas ntsuas ntsuas rau ntau qhov ntsuas ntsuas.Thaum siv lub sij hawm ntws, nco ntsoov nkag mus rau qhov ntsuas qhov ntsuas qhov tseeb rau cov khoom sib txuas.
3, portable ultrasonic flowmeter shortcomings thiab kev txwv
(1) Lub portable ultrasonic flowmeter ntawm lub sij hawm mus ncig teb chaws txoj kev tsuas yog siv los ntxuav cov kua thiab gases.
(2) Ultrasonic flowmeters nrog lwm cov transducers tsis tuaj yeem siv rau cov kav dej nrog cov ntaub tuab tuab lossis cov nplais, hauv zos dented lossis tsa cov kav dej, thiab cov kav dej uas muaj kev xeb loj ntawm cov yeeb nkab phab ntsa.
(3) Tam sim no kev tsim khoom hauv tsev ntawm cov ultrasonic flowmeters uas twb muaj lawm tsis tuaj yeem siv rau cov kav dej nrog cov kab uas hla tsawg dua DN25mm.
(4) Txoj kev loj hlob thiab kev tsim khoom ntawm domestic ultrasonic flowmeters tseem nyob rau hauv nws cov me nyuam mos, thiab tus nqi yog siab.
Kev ntsuas dej ntws yog qhov tseem ceeb hauv cov txheej txheem tsim khoom ntawm cov lag luam, tshwj xeeb tshaj yog nyob rau hauv kev txuag hluav taws xob thiab kev txuag dej thiab lwm yam kev tiv thaiv ib puag ncig tau siv ntau dua.Portable ultrasonic flowmeter yog ib hom tshiab ntawm flowmeter, nws yooj yim thiab kev lag luam yog lwm yam flowmeters tsis tuaj yeem bini.Txawm li cas los xij, ntau qhov yuam kev tsis raug tsim los ntawm cov cuab yeej zoo li no yuav tsum tau kawm txuas ntxiv thiab sib tham.Piv txwv li, kev hloov pauv ntawm thaj chaw ib puag ncig, lub zog zaus, kev ntsuas ntawm cov phab ntsa sab hauv ntawm cov yeeb nkab, thiab cov npuas hauv cov yeeb nkab yuav ua rau qee qhov kev hloov pauv ntawm qhov ntsuas qhov yuam kev.Yog li ntawd, tas li sau cov kev ntsuas qhov tseeb los ntawm kev xyaum, yog ib txoj haujlwm ntev los ua kom siv tau zoo ntawm portable ultrasonic flowmeters los ua nws txoj haujlwm zoo.
Portable ultrasonic flowmeter muaj cov yam ntxwv ntawm kev teeb tsa sai thiab siv tau yooj yim, tab sis nws yuav tsum paub qhov tseeb thaum siv.Tom qab xyoo dhau los ntawm kev ua haujlwm hauv kev ua haujlwm, nws pom tau tias kev siv lub tshuab nqus tsev ultrasonic flowmeters yog ib qho yooj yim uas yuav tsis quav ntsej, txheeb xyuas qhov ua rau muaj teeb meem thiab tawm tswv yim daws teeb meem.
