Em Flow Meters, tseem hu ua electromagnetic flow meter, feem ntau yog siv hauv kev lag luam khoom noj thiab dej haus rau lawv qhov tseeb, kev ntseeg tau, thiab tsis muaj qhov cuam tshuam. Hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm cov ntsuas ntsuas magnetic hauv kev tsim khoom noj thiab dej haus.
Em Flow Meters ua haujlwm raws li Faraday txoj cai ntawm electromagnetic induction. Lawv muaj ib lub raj ntws thiab ib khub ntawm electrodes uas yog mounted rau ntawm opposite sab ntawm lub raj. Ib qho chaw sib nqus yog siv rau lub raj xa dej, thiab thaum muaj cov kua hluav taws xob ntws los ntawm lub raj, nws tsim cov teeb liab voltage uas yog proportional rau tus nqi ntws. Cov teeb liab no yog tom qab ntawd hloov mus rau hauv digital lossis analog tso zis uas tuaj yeem siv rau kev saib xyuas lossis tswj lub hom phiaj.
Ib qho ntawm qhov zoo ntawm qhov ntawd yog lawv qhov tseeb, uas feem ntau yog nruab nrab ntawm ±{{0}}.5 feem pua thiab ± 1.0 feem pua. Qib no ntawm qhov tseeb yog qhov tseem ceeb hauv kev tsim khoom noj thiab dej haus vim tias kev ntsuas qhov tseeb yog qhov yuav tsum tau muaj rau kev tswj xyuas kom zoo thiab kev ua raws cai. Lawv tuaj yeem ntsuas tus nqi ntws hauv ntau qhov ntau thiab tsawg, los ntawm cov kav dej me me mus rau qhov loj. Lawv kuj tuaj yeem ntsuas cov nqi ntws hauv cov kua dej huv thiab cov kua dej uas muaj cov khib nyiab tshem tawm.
Lwm qhov kom zoo dua ntawm cov hlau nplaum ntws ntsuas yog lawv txoj kev ntseeg siab. Lawv tsis cuam tshuam los ntawm kev hloov pauv ntawm qhov kub thiab txias, siab, lossis viscosity, uas tuaj yeem cuam tshuam rau lwm hom ntws ntsuas. Lawv kuj tsis cuam tshuam los ntawm qhov muaj npuas lossis ua npuas dej, uas muaj ntau hauv cov txheej txheem tsim khoom noj thiab dej haus. Qhov no ua rau lawv zoo tagnrho rau kev siv xws li saib xyuas cov kua txiv hmab txiv ntoo, mis nyuj, npias, thiab lwm yam kua hauv kev tsim khoom noj thiab dej haus.
Lawv kuj tsis yog invasive, txhais tau tias lawv tsis xav tau kev sib cuag ncaj qha nrog cov kua ntsuas. Qhov no yog qhov tseem ceeb hauv kev tsim khoom noj thiab dej haus vim tias kev sib cuag ncaj qha nrog cov kua tuaj yeem ua rau nws paug thiab cuam tshuam nws qhov zoo. Lawv tsis muaj qhov txav mus los, uas txhais tau tias lawv yuav tsum tau saib xyuas me ntsis thiab muaj lub neej ua haujlwm ntev. Lawv kuj yog ib qho yooj yim rau nruab thiab tuaj yeem ua ke nrog lwm lub tshuab tswj.
Hauv kev tsim khoom noj thiab dej haus, Em flowmeter yog siv ntau yam kev siv, suav nrog:
1. Saib xyuas cov khoom siv raw
Lawv tuaj yeem siv los saib xyuas cov khoom siv raw xws li kua txiv hmab txiv ntoo, mis nyuj, thiab dej thaum lawv thauj los ntawm cov tso tsheb hlau luam mus rau cov khoom siv. Kev ntsuas qhov tseeb yog qhov tseem ceeb los xyuas kom meej qhov tseeb ntawm cov khoom siv raw khoom siv hauv kev tsim khoom.
2. Tswj kev khiav ntawm cov khoom xyaw
Lawv tuaj yeem siv los tswj cov dej ntws ntawm cov khoom xyaw xws li qab zib, ntsev, thiab cov txuj lom thaum lawv ntxiv rau cov txheej txheem tsim khoom. Qhov no pab kom muaj kev sib xws hauv qhov zoo thiab tsw ntawm cov khoom kawg.
3. Saib xyuas cov khoom ntws ntawm cov khoom tiav
Lawv tuaj yeem siv los saib xyuas cov khoom tiav xws li dej qab zib, npias, thiab cawv thaum lawv thauj los ntawm cov cuab yeej ua khoom mus rau lub tank cia lossis tshuab filling. Kev ntsuas qhov tseeb yog qhov tseem ceeb los xyuas kom meej tias cov khoom raug raug ntim thiab muag.
4. Kev ntsuas qhov ntws ntawm cov tshuaj ntxuav thiab dej
Lawv tuaj yeem siv los ntsuas qhov ntws ntawm cov tshuaj ntxuav thiab dej siv hauv kev ntxuav thiab ntxuav cov khoom siv ua haujlwm. Kev ntsuas dej kom raug yog qhov tseem ceeb los xyuas kom meej tias qhov tseeb ntawm tus neeg saib xyuas thiab dej siv rau kev tu kom zoo thiab kom tsis txhob muaj kev sib kis ntawm cov khoom kawg.
Muaj flowmeteryog ib qho tseem ceeb hauv kev tsim khoom noj thiab dej haus vim lawv qhov tseeb, kev ntseeg siab, tsis muaj kev cuam tshuam, thiab siv tau yooj yim. Lawv yog siv nyob rau hauv ntau yam kev siv, nrog rau kev soj ntsuam cov ntws ntawm raw cov ntaub ntawv, tswj cov ndlwg ntawm cov khoom xyaw, saib xyuas cov dej ntws ntawm cov khoom tiav, thiab ntsuas qhov ntws ntawm cov tshuaj ntxuav thiab dej. Lawv yog ib qho tseem ceeb ntawm kev tswj hwm kev ua tau zoo thiab kev ua raws cai hauv kev lag luam zaub mov thiab dej haus.
