Ключевые технические преимущества
-
Compact Wafer Design: With a standardized face-to-face length of only 65 mm (2.56 in), the Prowirl D can be sandwiched between existing pipe flanges. This minimal footprint makes it perfect for skid builders or plants where piping real estate is at a premium.
-
Orifice Plate Replacement: Because it requires no specialized flanging and is lightweight, it is designed for a 1-to-1 replacement of high-maintenance orifice plates. Unlike orifice plates, it provides a much wider turndown ratio and creates significantly less pressure drop.
-
Integrated Temperature Measurement: For saturated steam applications, the sensor includes an integrated temperature probe. This allows the device to calculate mass flow and energy flow directly, providing process transparency without the need for an external flow computer or separate temperature sensor.
-
Easy Alignment: To ensure measurement accuracy in a wafer configuration, the device comes with dedicated centering rings. These allow the user to align the sensor perfectly with the pipe bore, preventing flow disturbances that could lead to measurement errors.
-
Drift-Free DSC Sensor: The patented capacitive sensor is resistant to the harsh realities of steam service, including water hammer and thermal shocks. Its drift-free nature ensures that once the meter is installed, it maintains long-term calibration stability without the need for periodic zero-point adjustments.
-
Heartbeat Technology: The Prowirl D 200 includes integrated self-monitoring and verification. It can perform a traceable health check of the electronics and sensor integrity, generating a verification report that complies with quality management systems like ISO 9001.
