16.6 Performance characteristics
Reference operating
conditions
• Error limits based on ISO 11631
• Water with +15 to +45 °C (+59 to +113 °F) at2 to 6 bar (29 to 87 psi)
• Specifications as per calibration protocol
• Accuracy based on accredited calibration rigs that are traced to ISO 17025.
To obtain measured errors, use the Applicator sizing tool ( 93)
Maximum measured error o.r. = of reading; 1 g/cm³ = 1 kg/l; T = medium temperature
Base accuracy
Mass flow and volume flow (liquids)
±0.10 %
Mass flow (gases)

Design fundamentals ( 84)
Density (liquids)
• Reference conditions:±0.0005 g/cm³
• Standard density calibration:±0.02 g/cm³
(valid over the entire temperature range and density range )
• Wide-range density specification (order code for "Application package", option EF "Special
density and concentration" or EH " Special density and viscosity"): ±0.004 g/cm³ (valid
range for special density calibration: 0 to 2 g/cm³, +10 to +80 °C (+50 to +176 °F))
Temperature
±0.5 °C ± 0.005 · T °C (±0.9 °F ± 0.003 · (T – 32) °F)
