Endress+Hauser Promag W 400 Electromagnetic Flowmeter DN50 5W4C50-C6DLHA0AUA

The Endress+Hauser Promag W 400 is a robust electromagnetic flowmeter designed specifically for water and wastewater applications, offering reliable full-bore measurement without pressure loss. This model, with a nominal diameter of DN50 (2 inches), features Heartbeat Technology for continuous self-diagnostics, ensuring high operational reliability and compliance verification without process interruption. It supports industry-standard communication protocols like HART, PROFIBUS, and Modbus RS485, making it ideal for integration into automation systems. Key advantages include its liner made of polyurethane for abrasion resistance, suitability for buried installations, and IP68 protection for submersion. Compared to similar products like those from ABB or Siemens, the Promag W 400 excels in long-term stability and low maintenance due to its sensor design, which minimizes electrode cleaning needs. Benefits include accurate flow measurement (±0.2% accuracy), energy-efficient operation, and versatility in municipal water treatment, irrigation, and industrial effluent monitoring. Drawbacks may include higher initial cost and the need for conductive fluids (minimum conductivity 5 µS/cm). From the provided images, the unit appears new in original packaging, with no visible wear, and includes an integral transmitter for on-site display and configuration.
