Thaum muas lub clamp-on ultrasonic flowmeter, muaj ntau yam tseem ceeb los txiav txim siab kom ntseeg tau tias koj xaiv cov cuab yeej zoo rau koj daim ntawv thov tshwj xeeb. Cov yam ntxwv no tsis tsuas yog cuam tshuam rau qhov raug thiab kev ntseeg siab ntawm koj cov kev ntsuas ntws tab sis kuj cuam tshuam rau tus nqi-zoo thiab kev ua haujlwm ntev ntawm lub flowmeter. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv tsib yam tseem ceeb coj mus rau hauv tus account thaum muas ib tug clamp-on ultrasonic flowmeter.
1. Flowmeter Hom thiab Tshuab:
Thawj qhov yuav tsum tau xav txog yog hom clamp-on ultrasonic flowmeter thiab thev naus laus zis nws siv. Muaj ob hom tseem ceeb: kev thauj mus los-lub sijhawm thiab Doppler flowmeters.
Transit-time flowmeters yog qhov zoo tagnrho rau cov kua dej huv thiab tso siab rau qhov sib txawv ntawm lub sijhawm mus ncig ntawm ultrasonic cov cim qhia ntawm kev taw qhia thiab tawm tsam qhov ntws.
Doppler flowmeters, ntawm qhov tod tes, yog tsim rau cov kua dej uas raug tshem tawm los yog aeration thiab ua haujlwm los ntawm kev ntsuas qhov zaus hloov ntawm cov teeb liab cuam tshuam los ntawm cov khoom txav los yog npuas. Kev nkag siab txog koj cov kua dej thiab cov teeb meem kev ntsuas tshwj xeeb hauv koj daim ntawv thov yuav pab koj xaiv cov cuab yeej tsim nyog.
2. Cov khoom siv yeeb nkab thiab txoj kab uas hla:
Cov khoom siv ntawm cov yeeb nkab los ntawm cov dej ntws thiab nws txoj kab uas hla yog qhov tseem ceeb heev. Clamp-on ultrasonic flowmeters yog tsim los ua haujlwm nrog ntau yam khoom siv yeeb nkab, xws li hlau, yas, lossis pob zeb. Xyuas kom tseeb tias cov flowmeter koj xaiv tau sib xws nrog cov khoom siv yeeb nkab hauv koj lub cev.
Tsis tas li ntawd, txoj kab uas hla ntawm cov yeeb nkab cuam tshuam rau kev xaiv ntawm transducers lossis sensors. Xyuas kom meej tias lub flowmeter lub sensor loj haum rau koj cov yeeb nkab txoj kab uas hla thiab tso cai rau kev ntsuas kom raug.
3. Cov yam ntxwv ua kua:
Cov yam ntxwv ntawm cov kua dej ntsuas yog qhov tseem ceeb. Cov yam ntxwv xws li cov kua dej (kua lossis roj), qhov kub thiab txias, viscosity, thiab conductivity tuaj yeem cuam tshuam cov flowmeter kev ua haujlwm. Qee qhov ultrasonic flowmeters yuav muaj kev txwv thaum nws los ntsuas cov kua dej kub lossis cov kua dej khov heev. Kev nkag siab txog cov khoom ntawm koj cov kua dej yuav pab koj xaiv lub flowmeter uas tuaj yeem tswj cov yam ntxwv no yam tsis muaj kev cuam tshuam qhov tseeb.
4. Kev txhim kho thiab tu:
Qhov yooj yim ntawm installation thiab txij nkawm yog lwm yam tseem ceeb uas yuav tsum tau xav txog. Clamp-on ultrasonic flowmeters paub txog lawv cov kev teeb tsa uas tsis muaj kev cuam tshuam, uas txhais tau hais tias lawv tsis tas yuav txiav rau hauv cov yeeb nkab lossis cuam tshuam qhov ntws. Txawm li cas los xij, xav txog yam xws li kev nkag mus rau cov yeeb nkab, qhov xav tau rau tus kws tshaj lij installer, thiab qhov zaus ntawm kev saib xyuas yuav tsum tau ua. Qee cov flowmeters muaj cov yam ntxwv zoo xws li kev kuaj tus kheej thiab tsis siv neeg sensor ntxuav, uas tuaj yeem txo kev siv zog.
5. Qhov tseeb thiab calibration:
Qhov tseeb yog qhov tseem ceeb tshaj plaws hauv kev siv ntsuas ntsuas, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas qhov ntsuas qhov tseeb yog qhov tseem ceeb. Xyuas cov flowmeter cov lus qhia kom raug thiab rov ua dua. Tsis tas li ntawd, xav txog cov txheej txheem calibration. Qee qhov flowmeters yuav xav tau lub sijhawm rov ua dua kom muaj qhov tseeb. Nkag siab txog cov kev cai calibration thiab seb koj lub koom haum puas tuaj yeem ua tiav lawv yog qhov tseem ceeb rau kev ntseeg tau ntev.
Xaiv txoj caiclamp-on ultrasonic flowmeterYuav tsum ua tib zoo xav txog hom flowmeter, cov khoom siv yeeb nkab thiab txoj kab uas hla, cov yam ntxwv ntawm cov kua dej, kev teeb tsa thiab kev saib xyuas, thiab qhov tseeb thiab qhov xav tau calibration. Los ntawm kev soj ntsuam xyuas cov xwm txheej no thiab sab laj nrog cov kws tshaj lij ntsuas dej yog tias tsim nyog, koj tuaj yeem txiav txim siab paub meej uas ua kom qhov tseeb thiab txhim khu kev ntsuas ntsuas hauv koj daim ntawv thov tshwj xeeb. Kev nqis peev sijhawm thiab kev siv zog hauv kev xaiv qhov tsim nyog flowmeter ua ntej tuaj yeem ua rau kom txuag tau nyiaj mus ntev thiab txhim kho kev ua haujlwm zoo.
