Ndi njira iti yomwe singayesedwe ndi ma electromagnetic flowmeters?

Ma electromagnetic flowmeters si a anthu onse; makamaka sali oyenera kugwiritsa ntchito ma electromagnetic media otsika mphamvu, ma electromagnetic media okhala ndi zinthu zolimba zosokoneza, komanso ma electromagnetic media omwe amapitirira momwe meter imagwirira ntchito.

1. Zoulutsira mawu zopanda mphamvu zambiri

• Zida zoyatsira mpweya zomwe zili pansi pa malire a mita (nthawi zambiri ＜5μS/cm) sizingayesedwe, monga madzi oyera, madzi osungunuka, mafuta, mafuta, ndi dizilo.
• Zosungunulira zosiyanasiyana zachilengedwe (monga ethanol, methanol, acetone) zimalephera kupanga mafunde amphamvu, zomwe zimapangitsa kuti zizindikirozo zikhale zofooka kapena zisawonekere.

2. Zida zomwe zili ndi zinthu zosokoneza kwambiri

• Zipangizo zokhala ndi tinthu tambirimbiri ta maginito zidzasokoneza kufalikira kwa mphamvu ya maginito mkati mwa mita ndikuwononga mfundo yoyezera.
• Ma suspension okhala ndi mphamvu zambiri (monga matope okhala ndi dothi lambiri kapena ufa wachitsulo) amatha kutsekereza ma electrode kapena kuyambitsa minda yoyenda yosagwirizana, ndipo amatha kuwononga mkati mwake.

3. Zofalitsa zomwe zimadutsa mikhalidwe yogwirira ntchito yovomerezeka

• Zinthu zotenthetsera ndi kupanikizika kopitirira muyeso wa mita, monga kusungunuka kwa kutentha kwambiri ndi madzi ofunikira kwambiri, zidzawononga mkati ndi ma electrode.
• Zowononga kwambiri zomwe zimaposa kulekerera kwa elekitirodi/lining. Popanda kusankha zinthu zapadera zosagwirizana ndi dzimbiri, kuwonongeka kwa zigawo kudzachitika, zomwe zimapangitsa kuti muyeso ukhale wolakwika.
