Performance characteristics of the HPC sensor
4.3.1 Reference conditions
Established flow profile
Inlet section corresponds to the mounting length
Operation is to be performed with downstream control valves
Measurement is to be performed 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 4.5.1 Process temperature
on page 21
Process pressure is to be regulated as specified in Section 4.5.6 Process pressure range
on page 21
Ambient temperature is to range from + 10 °C to + 30 °C (50 °F to 86 °F)
Warm-up period: 15 minutes
Standard calibration shall be performed at 20 %, 50 % and 100 % (three times each)
High-frequency interference is to be regulated as specified in section 4.8.1 CE marking
on page 25.

4.3.3 Density measurement
The attainable accuracy depends on the selected calibration type.
With density measurement is deactivated in the density menu, no density measure-
ment is possible and empty pipe monitoring is not available!
