Quid est maximus vortex metrorum calibrationis fluxus range?

1. Typical Calibration Flow Ranges (per JJG 1029 & ISO 12764)

• Liquida (aqua, etc.):
  • Calibration range:0.3 ~ 700 m³/h(DN15-DN200)
  • Velocitas max:10 m/s
• Gases (air, gas naturale):
  • Calibration range:0.5 ~ 7,000 m³/h(DN15-DN300)
  • Velocitas max:60-80 m/s
• Vapor:
  • Calibration range:0.4 ~ 28,000 m³/h(magnum DN)
  • Velocitas max:70-80 m/s

2. Key limites Definire "Max flow"

• REYNOLDS numerus (Re):
  • Re minima linearis:2×10⁴(liquida) /4×10⁴(gas/steam)
  • Maximum Re:~7×10⁶(Superius terminus pro voragine stabilis effusione)
• Turndown ratio: Typice10:1(Max fluxus = 10 min fluxus)
• Meliorem calibration zona: 20%-80% metri nominalis range(X% -90% ad altum accuratam exempla)

3. Exemplum: DN100 Vortex Meter (Aquae)

• Nominal max fluxus:120 m³/h(≈4.2 m/s)
• Calibration range:12-120 m³/h(10:1 turndown)
• Calibration meliorem puncta:24, 48, 72, 96, 120;

4. Calibration Standard Requirements

• Minimum puncta test: 6(Including min et max fluxus)
• Liquor: Utere processu actuali fluido vel fluidomatching Reynolds numerus
