Endress+Hauser Proline Promag W 400 Electromagnetic Flowmeter

 (Order Code: 5W4C1F-AAALHA0AUD3S0D)

The Endress+Hauser 5W4C1F-AAALHA0AUD3S0D is a Proline Promag W 400 electromagnetic flowmeter, specifically designed for demanding water and wastewater applications . This versatile flowmeter features the innovative 0 x DN full bore technology, enabling reliable measurement without straight inlet or outlet runs and with no pressure loss, significantly reducing installation space and pumping energy costs .

Key Features & Benefits

• 0 x DN Full Bore Technology: Measures accurately without inlet/outlet runs—even directly after pipe bends, valves, pumps, or T-fittings. No pressure loss means reduced pumping energy costs .

• Heartbeat Technology: Integrated verification enables continuous self-diagnostics and on-demand compliance testing without process interruption. Includes build-up detection for proactive maintenance .

• High Accuracy & Reliability: ±0.5% o.r. ± 1 mm/s standard accuracy; optional ±0.2% o.r. ± 2 mm/s (Flat Spec) .

• International Drinking Water Approvals: Certified for potable water applications with ACS, KTW/W270, NSF 61, and WRAS BS 6920 .

• IP68 Protection: Suitable for direct underground installation or permanent underwater use. EN ISO 12944 corrosion protection for harsh environments .

• Flexible Communication: HART, Modbus RS485, PROFIBUS DP, EtherNet/IP. Integrated web server and WLAN for local operation without opening the device .

• Maintenance-Free Design: No moving parts eliminates wear and maintenance requirements .

Technical Specifications

Applications

FAQs

Q1: What does the "0 x DN" feature mean for installation?

A: The Proline Promag W 400 with "0 x DN full bore" technology requires no straight inlet or outlet runs. It can be installed directly after pipe bends, valves, pumps, or T-fittings without affecting measurement accuracy. This saves significant space in tight installations and eliminates pressure loss, reducing pumping energy costs .

Q2: What is Heartbeat Technology and how does it benefit my plant?

A: Heartbeat Technology provides continuous self-diagnostics, predictive maintenance recommendations (including build-up detection), and on-demand verification of the entire measuring point without process interruption. It helps optimize maintenance schedules, reduce unplanned downtime, and comply with ISO 9001 traceability requirements .

Q3: What approvals does this flowmeter have for harsh environment installations?

A: The Promag W 400 features IP68 / Type 6P enclosure protection and EN ISO 12944 C5-M/Im1/Im2/Im3 corrosion protection coating, making it suitable for direct underground installation or permanent underwater use. It also holds international drinking water approvals including ACS, KTW/W270, NSF 61, and WRAS BS 6920 .
