E+H Proline Promag W 400 Electromagnetic Flow Meter

The 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.

E+H transmitters do not require proprietary communication system, rather they offer full access to process and diagnostic information via numerous, freely combinable I/Os and fieldbuses. The W 400 allows for up to three analog or digital outputs. Digital communication options include HART, PROFIBUS DP, EtherNet/IP and Modbus RS485. This E+H flow meter is housed in an IP66/67, Type 4X enclosure standard, while IP68, Type 6P protection is also available as an option for the remote sensor. The IP68, Type 6P protection also includes a protective varnish according to EN ISO 12944 C5‐M/Im1/Im2/Im3.
