Ndeupi huwandu hwekuyerera kwevortex mita calibration?

1. Yakajairika Calibration Flow Ranges (pamwe neJJG 1029 & ISO 12764)

• Zvinwiwa (mvura, nezvimwewo):
  • Calibration range:0.3 ~ 700 m³/h(DN15–DN200)
  • Max velocity:10 m/s
• Magasi (mhepo, gasi rechisikigo):
  • Calibration range:0.5 ~ 7,000 m³/h(DN15–DN300)
  • Max velocity:60–80 m/s
• Steam:
  • Calibration range:0.4 ~ 28,000 m³/h(DN hombe)
  • Max velocity:70–80 m/s

2. Miganhu Yakakosha Inotsanangura "Max Flow"

• Reynolds nhamba (Re):
  • Minimum linear Re:2×10⁴(mvura) /4×10⁴(gasi/mupfu)
  • Maximum Re:~7×10⁶(yepamusoro muganho wekuteura yakagadzikana vortex)
• Turndown ratio: Kazhinji10:1(kuyerera kukuru = 10 × min kuyerera)
• Optimal calibration zone: 20% -80% yemamita emhando yezita(10% -90% yemhando yepamusoro-yechokwadi)

3. Muenzaniso: DN100 Vortex Meter (Mvura)

• Nominal max flow:120 m³/h(≈4.2 m/s)
• Calibration range:12–120 m³/h(10:1 kufuratira)
• Optimal calibration points:24, 48, 72, 96, 120 m³/h

4. Calibration Standard Zvinodiwa

• Minimum test points: 6(kusanganisira min uye max kuyerera)
• Fluid: Shandisa chaiyo process fluid kana mvura inekuenzanisa nhamba yaReynolds
