Electromagnetic flowmeter yuam kev teeb meem

Electromagnetic flowmeter yog cov cuab yeej siv dav siv los ntsuas cov dej ntws tawm, tab sis hauv kev siv, tej zaum yuav muaj teeb meem yuam kev, suav nrog kev ntsuas qhov tseeb, xoom drift thiab kub drift.Ntawm lawv, kev ntsuas qhov yuam kev yog hais txog qhov sib txawv ntawm tus nqi theoretical thiab ntsuas tus nqi, uas feem ntau tshwm sim los ntawm peb yam: voltage, tam sim no thiab electromagnetic teb.Zero drift txhais tau hais tias thaum lub sij hawm siv cov cuab yeej, yuav muaj qhov yuam kev, uas ua rau muaj qhov sib txawv loj ntawm qhov ntsuas qhov ntsuas thiab tus nqi tiag tiag.Qhov kub drift yog vim muaj kev cuam tshuam ntawm qhov kub thiab txias ntawm cov khoom siv hluav taws xob thiab electromagnetic coils, uas ua rau muaj kev cuam tshuam ntawm kev ntsuas qhov tseeb.
