Introduction
The Proline Promag W 400 is a versatile electromagnetic flowmeter purpose-built for the water and wastewater industry. With bidirectional measurement independent of pressure, density, temperature, and viscosity, it delivers reliable, constant-accuracy flow measurement with 0 x DN inlet run requirements and zero pressure loss. Optimized for water, wastewater, and utility applications, it features international drinking water approvals, IP68 ingress protection, and both compact and remote versions for flexible installation. Integrated Heartbeat Technology ensures continuous verification and measurement reliability, while its durable design and corrosion protection make it ideal for underground, underwater, and custody transfer applications.
