This manual covers the Endress+Hauser Proline Prowirl 72F, 72W, 73F, and 73W vortex flow measurement systems for gas, steam, and liquid applications.
The Proline Prowirl series provides reliable volume flow measurement for gases, steam, and liquids. The system features a robust DSC (Differential Switching Capacitive) sensor that ensures high stability against vibration and temperature shocks without requiring maintenance or having moving parts.
Prowirl 73 models include an integrated flow computer with built-in Pt1000 temperature measurement. This allows for the calculation of derived process variables such as mass flow, heat flow, and density based on IAPWS-IF97/ASME standards and various gas equations (AGA, ISO). The system supports communication protocols including HART, PROFIBUS PA, and Foundation Fieldbus. This manual is written in Chinese.
The system is designed for a fluid temperature range of –200 to +400 °C (–328 ... +752 °F).
The system supports pressure ratings up to PN 250 or Class 1500.
It calculates mass flow based on volume flow measurement values and temperature measurement values.
