1) Electromagnetic flowmeter xav tau cov yeeb nkab ncaj uas luv dua li ultrasonic flowmeter's.Electromagnetic flowmeter installation site tej zaum yuav tsis ncaj cov yeeb nkab, yog li sib piv ntawm qhov chaw, xyuam xim rau txoj hauj lwm ntawm kev ntsuas seb puas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov yeeb nkab ncaj ultrasonic flowmeter, yog tias tsis ua raws li cov yeeb nkab ncaj nraim yuav tsum nyob ze ntawm qhov kev xaiv ua raws li txoj haujlwm. Kev ntsuas ultrasonic flowmeter, kev sib piv cov txiaj ntsig yuav tsis raug.
2) Xyuas seb qhov kev teeb tsa ntawm lub tshuab electromagnetic flowmeter puas ua tau raws li qhov yuav tsum tau ua ntawm cov kua ntws (xws li cov khoom siv hluav taws xob, seb lub installation puas nyob rau hauv qis qis ntawm cov kav dej, seb cov npuas puas tuaj yeem tsim, thiab lwm yam).Yog tias tsis yog, nws yuav tsum tau thov rau tus neeg siv tias qhov no yuav yog qhov ua rau muaj teeb meem.
3) Electromagnetic flowmeter yog ib qho cuab yeej zoo los ntsuas qhov ntws ntawm cov kua hluav taws xob.Nws qhov ntsuas qhov tseeb kuj yog siab heev, feem ntau yog 0.5%, thiab nws yog qhov zoo tshaj kom ncav cuag 0.2%.Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau cov chaw tsim khoom ntawm electromagnetic flowmeter.Yog tias cov khoom lag luam tau teeb tsa yam tsis muaj qhov yuam kev thiab cov kua dej ua tau raws li qhov yuav tsum tau ua, qhov ntsuas tus nqi yuav tsum ua tib zoo xav, thaum rau cov tuam txhab uas tsis yog cov khoom lag luam tseem ceeb, raws li cov khoom siv hluav taws xob hluav taws xob muaj txiaj ntsig zoo thiab qhov yuam kev loj, koj tuaj yeem ua siab tawv kom tsis ntseeg.
4) Nkag siab txog cov khoom siv ntawm lub raj xa dej, seb puas muaj hauv ob sab phlu, scaling thiab lwm yam tshwm sim nrog rau cov kev tsis sib xws ntawm cov raj xa dej los ntawm tus neeg siv.Polish lub raj xa dej thaum txhim kho lub ultrasonic sensor, thiab xaiv Z txoj kev ntsuas thiab sib piv kom deb li deb tau.
5) Cov kua uas tuaj yeem ntsuas tau los ntawm ultrasonic flowmeter tsis cuam tshuam los ntawm cov conductivity.Yog tias tus nqi ultrasonic ruaj khov thaum tus nqi hluav taws xob tsis ruaj khov thaum sib piv, nws qhia tau hais tias qhov kev ntsuas ntawm lub cev ntws tau ntsuas yog nyob rau thaj tsam ntawm qhov ntsuas, tsis yog tshwm sim los ntawm cov kua dej uas muaj roj, thiab tus nqi ntawm ultrasonic. flowmeter yog credible.Yog tias ob qho tib si tsis ruaj khov nyob rau tib lub sijhawm, qhov ua tau ntawm npuas yog ntau dua.
6) electromagnetic flowmeter yuav tsum tau ntsuas cov kua yuav tsum muaj peev xwm sib npaug nrog lub ntiaj teb, txwv tsis pub yuav muaj kev cuam tshuam kev ntsuas, yog li thaum av tsis raug lossis tsis zoo hauv av (electromagnetic grounding muaj ntau txoj hauv kev thiab nruj), yuav muaj teeb meem. , yuav tsum xyuas qhov xwm txheej hauv av.Piv nrog ultrasonic flowmeter, tsis muaj peev xwm yuav tsum tau ua kua.Yog hais tias grounding yog questionable, tus nqi ntawm ultrasonic flowmeter yog lawm.
7) Yog tias muaj kev cuam tshuam hluav taws xob thiab cov chaw sib nqus nyob ze, qhov cuam tshuam ntawm ultrasonic flowmeter tsawg dua li ntawm electromagnetic flowmeter, thiab kev ntseeg siab ntawm ultrasonic zaub nqi yuav tsum ntau dua li ntawm electromagnetic flowmeter.
8) Yog tias muaj qhov cuam tshuam lub suab hauv cov raj xa dej (xws li lub suab tsim los ntawm qhov sib txawv loj sib txawv siab tswj lub valve), qhov cuam tshuam ntawm ultrasonic yog ntau dua li ntawm electromagnetic, thiab kev ntseeg siab ntawm electromagnetic indications tus nqi yog ntau dua li ntawd. ntawm ultrasonic.
