Introduction
The Endress+Hauser Proline Promag W 500 is a premium electromagnetic flowmeter designed specifically for demanding water and wastewater applications. It offers reliable, pressure-loss-free measurement with IP68 protection, remote configuration, and Heartbeat Technology, making it ideal for municipal, industrial, and custody transfer projects.
Key advantages
1. Unmatched range for water applications: Covers DN 25 to 3000 (1" to 120") with a measuring range up to 263,000 m³/h, suitable for large-scale water and wastewater systems.
2. IP68 protection for harsh environments: Rated IP68 (Type 6P) with EN ISO 12944 corrosion protection, approved for underground or underwater installations.
3. Custody transfer accuracy: Meets MI-001/OIML R49 standards with ±0.2% optional accuracy, ideal for billing and custody transfer applications.
4. Flexible remote configuration: Supports up to 4 I/Os with freely combinable fieldbuses and WLAN access, enabling easy integration and remote monitoring.
5. Drinking water compliant: Features international drinking water approvals (ACS, NSF 61, WRAS), safe for use in potable water distribution networks.
