Kif taħdem
Il-miter tal-fluss ultrasoniku tal-kanal doppju / miter tas-sħana jkejjel ir-rata tal-fluss attwali f'kull punt fil-pipeline permezz ta 'żewġ gruppi ta' sensuri, jissimula d-distribuzzjoni tar-rata tal-fluss fil-pipeline waqt it-tħaddim attwali, u ssolvi l-eżattezza tal-konverżjoni tal-veloċità lineari V fil-veloċità tal-wiċċ Ѷ Biex titjieb l-eżattezza ġenerali tal-kejl tal-istrument.
Il-miter tal-fluss ultrasoniku tal-kanal doppju / miter tas-sħana jittrasmetti u jirċievi mewġ ultrasoniku lil xulxin permezz tas-sensuri ta 'fuq u' l isfel. Meta r-raġġ ultrasoniku jinfirex fil-likwidu, il-fluss tal-likwidu jagħmel bidla żgħira fil-ħin tal-propagazzjoni, u l-bidla fil-ħin tal-propagazzjoni hija proporzjonali għar-rata tal-fluss tal-likwidu, kif muri fil-figura.

Il-miter tal-fluss tas-sħana ultrasoniku b'żewġ kanali huwa l-iktar tip komuni ta ' flowmeter tal-kesħa jew tas-sħana tagħna, li huwa wkoll wieħed mill-aħjar metri tal-bejgħ. Minbarra l-produzzjoni tal-miter tal-fluss tal-kesħa jew tas-sħana, aħna nipproduċu wkoll miter tal-fluss u meter jew strumenti tal-livell , jekk inti interessat, jekk jogħġbok ikkuntattjana.
