Proline Promag L 400 Electromagnetic flowmeter
Summary:

Promag L is theversatile standard sensor designed for the water industry with a lap-jointflange concept for flexible installation independent of the orientation of thepipe flange pitch diameter. Combined with Proline 400, the transmitter foroptimized measurement of water and wastewater, Promag L 400 will be thepreferred solution for all standard applications in this industry. Promag L 400also offers an integrated web server. Integrated verification with HeartbeatTechnology.

Benefits

Reducedinstallation costs – flexible mounting by one-of-a-kind lap-joint flangeconcept (DN < 350/14")

Energy-savingflow measurement – no pressure loss due to cross-section constriction

Maintenance-free– no moving parts

Safe operation –no need to open the device due to display with touch control, backgroundlighting

Time-savinglocal operation without additional software and hardware – integrated webserver

Integratedverification – Heartbeat Technology™
