E+H Proline Promag W 400 electromagnetic flow meter measures volume flow, conductivity and mass flow. It features certified corrosion protection (EN ISO 12944) for underground or permanent underwater installation making it an ideal fit in water, wastewater and custody transfer industries. The bidirectional measuring principle is not dependent on pressure, density, temperature and viscosity. Because it has no moving parts, the Promag W 400 is maintenance-free and applications suffer no pressure loss due to cross-section constriction.
