Reference operating
conditions
• Error limits based on ISO 11631
• Dry air with +20 to +30 °C (+68 to +86 °F) at 0.8 to 1.5 bar (12 to 22 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 → 161

Calibrated measuring range
The measuring accuracy is specified in relation to the mass flow and divided into two
ranges:
• ±1.0 % of the current measured value for 100% to 10% of the calibrated measuring
range (under reference operating conditions)
• ±0.10 % of the calibrated full scale value for 10% to 1% of the calibrated measuring
range (under reference operating conditions)
The measuring device is calibrated and adjusted on an accredited and traceable calibration
rig and its accuracy is certified in a calibration report
1)
(5 control points).
Order code for "Calibration flow":
• Option G "Factory calibration": calibration report (5 control points)
• Option K "Traceable ISO/IEC17025": Swiss Calibration Services (SCS) calibration report (5
control points) which confirms traceability to the national calibration standard

Extended measuring range
The device has an extended measuring range that goes beyond the maximum calibrated
value (100%). Here, the last measured values in the calibrated range are taken and then
extrapolated. The end of the extrapolated range is only reached once the productive
energy of the sensor is exceeded and/or the Mach number is greater than listed below.
