What is the Proline Promag W 500?

The Proline Promag W 500 is a high-performance electromagnetic flowmeter made by Endress+Hauser, specifically engineered for demanding water and wastewater applications. It features a remote transmitter configuration, offering up to four versatile I/O channels for flexible integration into complex systems

Key Features & Benefits

1. Unrivaled Installation Flexibility

• 0 × DN Full-Bore Design: The only electromagnetic flowmeter that operates accurately without the need for inlet or outlet straight pipe runs—eliminating the need for space and reducing pressure loss
• Ideal for tight or cluttered installations, such as skid-mounted systems or areas with frequent pipeline bends or disturbances

2. High Accuracy & Reliable Measurement

• Accuracy: Standard accuracy is ±0.5% of reading ±1 mm/s; optional "Flat Spec" accuracy improves to ±0.2% of reading ±2 mm/s
• Multi-electrode, bidirectional measurement ensures accurate flow detection regardless of flow profile, pressure, density, temperature, or viscosity

3. Wide Range of Operating Conditions

• Measuring Range: 0.5 m³/h to 263,000 m³/h (approx. 2.5 gal/min to 1,665 Mgal/day)
• Medium Temperature Range:
• Hard rubber liner: 0–80 °C (32–176 °F)
• Polyurethane liner: –20–50 °C (–4–122 °F)
• PTFE liner: –20–90 °C (–4–194 °F) (noted in specifications)
• Pressure Rating: PN 40 / Class 300 / 20K
• Wetted Materials: Options include hard rubber, polyurethane, PTFE liners, with electrodes made from stainless steel (316L), Alloy C22, tantalum

4. Durable & Certified Design

• Enclosure: Up to IP68 (Type 6P) for submergence and direct burial applications
• Corrosion Resistance: Meets EN ISO 12944 standards; suitable for underground or underwater installations
