Critical Technical Advantages
-
Multivariable Capability: Prowirl F 200 integrates temperature and pressure measurement directly. This allows the device to calculate compensated mass flow and energy flow for steam and gases internally, eliminating the need for external flow computers and additional piping penetrations.
-
Inline Wet Steam Measurement: For sizes DN 25 to 300 (1 to 12 inches), the meter can detect and monitor steam quality. This feature is critical for preventing water hammer, protecting downstream equipment, and ensuring the highest energy efficiency in steam systems.
-
PremiumCal Accuracy: The PremiumCal option ensures the highest measuring accuracy even at low flow rates. The meter body is engineered to maintain linearity down to a Reynolds number (Re) of 10,000, allowing for precise measurement across a wide range of process conditions.
-
Heartbeat Technology: Integrated diagnostics and verification allow for continuous monitoring of the device’s health. Verification can be performed without interrupting the process, ensuring long-term safety and reducing the frequency of physical calibrations.
-
Robust Capacitive Sensor: The patented sensor design is drift-free and immune to thermal shocks and water hammer. This mechanical durability is essential for steam applications where sudden pressure or temperature changes are common.
-
Dual-Compartment Housing: The transmitter is designed with a separate connection compartment. This allows for safe wiring and maintenance without exposing the sensitive electronics to harsh industrial environments.
