1. Product Overview: The Prowirl D 200 (7D2C) Advantage

The E+H Proline Prowirl D 200 (Order code family: 7D2C) is a multivariable vortex flowmeter in a wafer design, succeeding the 7D2B series and setting a new standard for cost-effective steam measurement . Its key differentiator is the wafer-style body, which allows it to be clamped directly between pipeline flanges, eliminating the need for mating flanges and significantly reducing both weight and installation costs .

Despite its compact form, it integrates Heartbeat Technology for continuous diagnostics and on-demand verification without process interruption . With genuine loop-powered two-wire technology, the E&H 7D2C vortex flowmeter ensures seamless and economical integration into existing control infrastructures . It is the preferred choice for 1-to-1 replacement of orifice plates and for general-purpose applications where reliability and simplicity are key .

Key Technical Differentiators:

Wafer-Style Design: Features a standardized 65 mm (2.56 in) face-to-face length across all sizes, simplifying piping design and installation .

Integrated DSC Sensor: Provides built-in temperature measurement for direct mass or energy flow calculation of saturated steam .

Simplified Installation: Comes with centering rings for easy alignment between flanges, eliminating complex measurements .

High Robustness: Proven resistance to vibration, temperature shocks, and water hammer, ensuring long-term reliability

2. The 7D2C Series: A Model for Every Wafer Application

The E&H 7D2C vortex flowmeter series is segmented into 7 primary model designators based on nominal diameter (line size). Below is the complete list of base models available through ST-YUKE CO., LIMITED:

7D2C15 (DN 15 / ½”)

7D2C25 (DN 25 / 1″)

7D2C40 (DN 40 / 1 ½”)

7D2C50 (DN 50 / 2″)

7D2C80 (DN 80 / 3″)

7D2C1H (DN 100 / 4″)

7D2C1F (DN 125 / 5″)

Note: The series typically covers up to DN 150 (6″), ensuring comprehensive coverage for most ancillary process lines .

3. Deep Dive: Decoding the 7D2C15-AAAABAABAAAASKA1+AA

Understanding the Endress+Hauser ordering code is critical for ensuring the device meets specific process conditions. ST-YUKE CO., LIMITED provides expert configuration assistance. Below is a technical breakdown of the specific variant: 7D2C15-AAAABAABAAAASKA1+AA.
