10.1.6 Performance characteristics
Reference operating
conditions
• Error limits following ISO/DIS 11631
• Water, typically 20 to 30 °C (68 to 86 °F); 2 to 4 bar (30 to 60 psi)
• Data as per the calibration report ±5 °C (±9 °F) and ±2 bar (±30 psi)
• Data on the measured error based on accredited calibration rigs traced back to ISO 17025
Maximum measured error The values indicated refer to the pulse/frequency output.
The additional measured error for the current output is typically ±5 μA.
