Electromagnetic flowmeteryog haum rau cov xov xwm conductive. Pipeline xov xwm yuav tsum tau sau nrog cov yeeb nkab ntsuas. Nws yog tsuas yog siv nyob rau hauv lub Hoobkas dej phwj, dej phwj hauv tsev, thiab lwm yam.
Cia peb xub paub tias qhov xwm txheej no tshwm sim li cas?
Lub instantaneous flow ntawm lub electromagnetic flowmeter yog ib txwm 0, dab tsi yog qhov teeb meem? Yuav daws li cas?
1. Qhov nruab nrab tsis yog conductive;
2. Muaj dej ntws hauv cov kav dej tab sis tsis puv;
3. Tsis muaj dej ntws hauv cov kav dej electromagnetic flowmeter;
4. Cov electrode yog npog thiab tsis sib cuag nrog cov kua;
5. Cov dej ntws tsawg dua qhov qis qis ntawm cov dej ntws txiav tawm hauv lub 'meter';
6. Qhov kev teeb tsa tsis raug hauv lub 'meter' header tsis raug;
7. Lub sensor puas lawm.
Tam sim no peb paub tias yog vim li cas, peb yuav tsum zam qhov teeb meem no li cas tam sim no. Thaum xaiv thiab txhim kho electromagnetic flowmeters, koj yuav tsum tau them sai sai rau:
1. Ua ntej, kev ntsuas ntsuas ntawm chav tsev no yuav tsum tau txhais kom meej. Muaj ntau yam kev ntsuas, feem ntau: ntsuas nruab nrab, ntws m3 / h (yam tsawg kawg, ua haujlwm taw tes, siab tshaj), nruab nrab kub ℃, nruab nrab siab MPa, daim ntawv installation (flange hom, Clamp hom) thiab lwm yam.
2. Yam yuavtsum tau kawm uantej rau kev xaiv
electromagnetic flowmeter1) Cov ntsuas nruab nrab yuav tsum yog cov kua ua kua (uas yog, cov kua ntsuas yuav tsum muaj qhov tsawg kawg nkaus conductivity);
2) Qhov ntsuas nruab nrab yuav tsum tsis txhob muaj cov ferromagnetic ntau dhau los yog ntau cov npuas.
