Critical Technical Advantages
-
Integrated Diameter Reduction: The Prowirl R features a built-in reduction of either 1 or 2 line sizes (e.g., a DN 100 pipe can use a sensor reduced to DN 80 or DN 50). This raises the Reynolds number at the sensor, allowing for accurate measurement of very low flow rates that a full-bore meter would miss.
-
Cost-Effective Retrofitting: Traditionally, reducing line sizes requires external reducers, expanders, and additional welding. The Prowirl R eliminates these pipework modifications, saving significant installation time and material costs while maintaining the original face-to-face dimensions of a standard meter.
-
Multivariable Energy Management: The R 200 integrates temperature and pressure measurement directly into the transmitter. This allows for real-time calculation of mass and energy flow for steam and gases, which is essential for accurate carbon reporting and boiler efficiency monitoring.
-
PremiumCal Accuracy: Equipped with the PremiumCal calibration option, the meter guarantees excellent measuring accuracy. It remains linear and dependable down to a Reynolds number (Re) of 10,000, ensuring high plant availability even during periods of low demand.
-
Heartbeat Technology: This integrated verification suite enables continuous self-diagnostics. You can verify the device’s health and performance without interrupting the process, ensuring documented safety and potentially extending calibration cycles.
-
Robust Capacitive Sensor: The patented sensor design is drift-free and highly resistant to the thermal shocks and water hammer often found in steam systems. This ensures long-term stability and reduces the total cost of ownership.
