Proline Promag W 400
electromagnetic flowmeter

Electromagnetic

Versatile standard flowmeter for the water and wastewater industry.
Reliable measurement at constant accuracy with 0 x DN inlet run and no pressure loss.
Ideal for water measurement, e.g. drinking water, utility water and industrial/municipal wastewater.

Flexible engineering – sensor with fixed or lap-joint process connections. Application fitness – EN ISO 12944 corrosion protection for underground or underwater installation. Improved plant availability – sensor compliant with industry-specific requirements.
International drinking water approvals. Degree of protection IP68 (Type 6P enclosure). Approved for custody transfer to MI-001/OIML R49.

Safe operation – no need to open the device due to display with touch control, background lighting. Time‐saving local operation without additional software and hardware – integrated web server. Integrated verification – Heartbeat Technology.
Transmitter housing made of durable polycarbonate or aluminium. WLAN access. Integrated data logger: measured values monitoring.
