Ma electromagnetic flowmeters haasi epasi rose; haana kukodzera zvakanyanya kune ma low conductivity media, ma multimedia ane zvikamu zvakasimba zvinopindira, uye ma multimedia anopfuura mamiriro ekushanda akajairwa ne meter.
1. Midhiya isina kufambisa simba zvakanyanya
- Midhiya ine conductivity iri pasi pemuganho wemita (kazhinji ＜5μS/cm) haigone kuyerwa, senge mvura yakachena, mvura yakasanganiswa, peturu, peturu, uye dhiziri.
- Zvinonyungudutsa zvakasiyana-siyana (semuenzaniso, ethanol, methanol, acetone) zvinokundikana kugadzira mafungu anokonzerwa nemagetsi anoshanda, zvichikonzera kusasimba kwesimba kana kusavapo kwezviratidzo.
2. Midhiya ine zvinhu zvakasimba zvinokanganisa
- Midhiya ine zvidimbu zvakawanda zvemagineti ichakanganisa kugoverwa kwesimba remagineti mukati memita uye ichakanganisa musimboti wekuyera.
- Zvimisikidzo zvine hunyoro hwakawanda (semuenzaniso, matope ane sediment yakawanda kana upfu hwesimbi) zvinowanzovhara maelectrode kana kukonzera minda yekuyerera isina kuenzana, uye zvinogona kukanganisa lining.
3. Midhiya inodarika mamiriro ekushanda akatarwa
- Zvinhu zvine tembiricha nekumanikidzwa zvinopfuura mwero wemita, zvakaita sekunyunguduka kwetembiricha yepamusoro uye mvura dzinoshandiswa zvakanyanya, zvinokuvadza jira nemaerekitironi.
- Midhiya inoparadza zvakanyanya inodarika kutsungirira kweelectrode/lining. Pasina kusarudza zvinhu zvakakosha zvinodzivirira ngura, zvikamu zvinokuvara, zvichikonzera kuyerwa kusina kururama.
