Kev ntsuas txoj cai
Mag meter ua haujlwm raws li Faraday txoj cai lij choj, thiab ntsuas qhov nruab nrab ntawm cov khoom siv hluav taws xob ntau dua 5 μs / cm3 thiab ntws ntau ntawm 0.2 txog 15 m / s.Ib qho Electromagnetic Flowmeter yog lub ntsuas hluav taws xob uas ntsuas qhov nrawm nrawm ntawm cov kua hauv cov yeeb nkab.
Kev ntsuas lub hauv paus ntsiab lus ntawm magnetic flowmeters tuaj yeem piav qhia raws li hauv qab no: thaum cov kua nkag mus hauv cov yeeb nkab ntawm qhov ntws ntawm v nrog txoj kab uas hla D, nyob rau hauv uas sib nqus flux ntom ntom ntawm B yog tsim los ntawm cov coil zoo siab, cov nram qab no electromotive E yog. generated in proportion to flow speed v:
E = K × B × V × D
Qhov twg: E - Induced electromotive quab yuam K - Meter tsis tu ncua B - Sib nqus induction ntom ntom V - Qhov nruab nrab ntws ceev hauv ntu ntu ntawm ntsuas raj D - Sab hauv txoj kab uas hla ntawm ntsuas lub raj |
