Kodi kuchuluka kothamanga kwa ma vortex mita calibration ndi chiyani?

1. Mayendedwe Ofananira Nawo (pa JJG 1029 & ISO 12764)

• Zamadzimadzi (madzi, etc.):
  • Ranji yoyezera:0.3 ~ 700 m³/h(DN15–DN200)
  • Kuthamanga kwakukulu:10 m/s
• Mpweya (mpweya, gasi wachilengedwe):
  • Ranji yoyezera:0.5 ~ 7,000 m³/h(DN15–DN300)
  • Kuthamanga kwakukulu:60–80 m/s
• Steam:
  • Ranji yoyezera:0.4 ~ 28,000 m³/h(DN wamkulu)
  • Kuthamanga kwakukulu:70–80 m/s

2. Malire Ofunika Amene Amatanthauza "Max Flow"

• Reynolds nambala (Re):
  • Zocheperako zofananira Re:2 × 10 pa(madzi) /4 × 10 pa(gasi/ nthunzi)
  • Maximum Re:~7×10⁶(malire apamwamba a kukhetsa kokhazikika kwa vortex)
• Chiŵerengero cha kubweza: Nthawi zambiri10:1(kuthamanga kwakukulu = 10 × mphindi kuyenda)
• Mulingo woyenera kwambiri wa calibration zone: 20% -80% ya mtundu wa mita(10%–90% pamitundu yolondola kwambiri)

3. Chitsanzo: DN100 Vortex Meter (Madzi)

• Nominal max flow:120m³/h(≈4.2 m/s)
• Ranji yoyezera:12–120 m³/h( 10:1 kutembenuka)
• Mulingo woyenera kwambiri wa ma calibration:24, 48, 72, 96, 120 m³/h

4. Zofunikira za Calibration Standard

• Zochepa zoyeserera: 6(kuphatikiza min ndi max flow)
• Madzi: Gwiritsani ntchito njira yeniyeni yamadzimadzi kapena madzimadzi ndiyofanana ndi nambala ya Reynolds
