o.r. = of reading; 1 g/cc = 1 kg/l; T = medium temperature
• Mass flow and volume flow (liquid): ±0.15% o.r.
• Mass flow (gas): ±0.50% o.r.
• Density (liquid)
±0.0005 g/cc (under reference conditions)
±0.0005 g/cc (after field density calibration under process conditions)
±0.002 g/cc (after special density calibration)
±0.02 g/cc (over the entire measuring range of the sensor)
• Special density calibration (optional):
– Calibration range: 0.0 to 1.8 g/cc, +5 to +80 °C (+41 to +176 °F)
– Operation range: 0.0 to 5.0 g/cc, –50 to +200 °C (–58 to +392 °F)
• Temperature: ±0.5 °C ± 0.005 · T °C; (±1 °F ± 0.003 · (T - 32) °F)
