Accuracy
Standard accuracy limits for the IGTM-CT are in accordance with the MID directive (2004/22/EC) and many other regulations:
± 1% for 0.2 Qt to Qmax (Range 1:20: Qt = 0.2 Qmax)
± 2% for Qmin to 0.2 Qt (Range ≥1:30: Qt = 0.2 Qmax)

As an option the accuracy limits can be improved to:
± 0.5% for 0.2 Qt to Qmax
± 1% for Qmin to 0.2 Qt”
