Key Features and Benefits
-
Designed for High-Pressure Applications: The Prowirl O 200 is the preferred choice for high-pressure steam and gas measurement, with saturated steam mass flow capability up to PN 250 (Class 1500). Its special sensor design ensures increased mechanical integrity for demanding high-pressure piping systems.
-
Full NACE Compliance: The device offers full compliance with NACE MR0175/MR0103 standards, making it suitable for applications with aggressive media and corrosive environments.
-
Integrated Multivariable Measurement: Integrated temperature and pressure measurement enables better process control for steam and gases, including energy flow and heat flow difference calculations.
-
Superior Accuracy and Linearity: Consistently delivers same accuracy down to Reynolds number Re 10,000, offering one of the most linear vortex meter bodies available. Volume flow accuracy for liquids is ±0.75%, and ±1.00% for steam and gas.
-
Long-Term Stability: Features a robust drift-free capacitive DSC sensor that resists vibration, temperature shocks (>150 K/s), and water hammer, ensuring reliable measurement without recalibration over extended periods.
-
Safe and Convenient Operation: The transmitter features a separate connection compartment for convenient wiring and a 4-line backlit display with touch control for safe operation without opening the device.
-
Integrated Heartbeat Technology: Built-in verification ensures measurement reliability, enables traceable verification according to ISO 9001 (TÜV SÜD attestation), and allows extension of recalibration cycles without process interruption.
