Technical data
Flow rate measurement
• Measurement range
• Accuracy, after a teach-in calibration has been made
• Accuracy, with the K factor of the fitting used
• Linearity
• Repeatability
• 0,2 to 10 m/s
• ±0,5 % of the measured value
1)
• ±3,5 % of the measured value
1)
• ±0,5 % of the full scale
1)
• ±0,25 % of the measured value
1)
Determined in the following reference conditions: fluid = water, water and ambiant temperatures = 20 °C, upstream and
downstream distances respected, appropriate pipe dimensions.
