Critical Technical Advantages
-
High-Pressure Engineering: The Prowirl O is uniquely designed for high-pressure environments, capable of calculating saturated steam mass flow at pressures up to PN 250 or ASME Class 1500. This makes it ideal for high-pressure steam headers and gas injection systems.
-
Multivariable Process Control: Like the F-series, the Prowirl O 200 features integrated temperature and pressure measurement. This allows for real-time calculation of mass and energy flow for steam and gases, providing superior process control without the complexity of external instrumentation.
-
NACE MR0175/MR0103 Compliance: To ensure safety in “sour” environments, the Prowirl O is available in full compliance with NACE standards. This prevents sulfide stress cracking and ensures long-term mechanical integrity when measuring corrosive gases.
-
Specialized Sensor Design: The sensor is specifically reinforced for high-pressure service while maintaining the signature Endress+Hauser drift-free capacitive technology. This ensures the meter remains resistant to vibrations, water hammer, and thermal shocks even at extreme pressures.
-
Premium Linearity: The meter body is engineered to provide the same high accuracy down to a Reynolds number (Re) of 10,000. This linearity is critical for maintaining measurement reliability across a wide range of flow velocities and pressures.
-
Heartbeat Technology: Integrated self-monitoring and verification allow the device to be checked against its original factory calibration without stopping the process. This ensures constant safety and extends the time between required physical inspections.
