Critical Technical Advantages
-
Compact Wafer Design: With a face-to-face length of only 65 mm (2.56 in), the Prowirl D is engineered for tight spaces. It significantly reduces installation costs and weight compared to flanged meters, making it perfect for utility lines and skid-mounted equipment.
-
Orifice Plate Replacement: The Prowirl D is specifically designed as a 1-to-1 replacement for orifice plates. It provides a much wider turndown ratio and lower pressure drop than differential pressure flowmeters, resulting in improved accuracy and energy savings.
-
Integrated Temperature Measurement: For saturated steam applications, the sensor includes integrated temperature measurement. This allows the device to calculate mass and energy flow internally without the need for additional external sensors or flow computers.
-
Easy Alignment: To ensure measurement accuracy in a flangeless design, the Prowirl D comes with centering rings. These simplify installation and ensure the sensor is perfectly aligned with the pipe bore to prevent flow profile disturbances.
-
Proven Sensor Robustness: The meter utilizes a robust, drift-free capacitive sensor that is resistant to vibrations, temperature shocks, and water hammer—common issues in steam and high-velocity gas lines.
-
Safe Operation and Wiring: The dual-compartment housing allows for a separate connection compartment, ensuring electronics remain protected during wiring. The display features touch control and background lighting, enabling operators to configure the device safely without opening the housing in hazardous areas.
