3.4 Performance characteristics of the CMB sensor
3.4.1 Reference conditions
• Established flow profile
• Inlet section has to correspond to mounting length
• Operation is to be realized in the presence of downstream control valves
• Measurement is to be realized in the absence of any gas bubbles
• Flow tubes are to be kept clean at all times
• Process temperature is to be regulated as specified in Section 3.6.1 Process temperature on
page 23
• Process pressure is to be regulated as specified in Section 3.6.6 Process pressure range on
page 23
• Ambient temperature is to range from + 10 °C to + 30 °C (50 °F to 86 °F)
• Warm-up period: 15 minutes
• Standard calibration is to be realized at 20 %, 50 % and 100 % (three times each)
• High-frequency interference is to be regulated as specified in Section 17.2 Electromagnetic
