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.
