Promag L is the versatile standard sensor for the water and wastewater industry with a lap-joint flange concept for flexible installation independent of the orientation of the pipe flange pitch diameter. Combined with the Promag 10 transmitter for basic applications and direct integration, Promag 10L offers accurate measurement of liquids for a wide range of applications. It will be the preferred solution for customers aiming for minimized cost of ownership.
● Reduced installation costs – flexible mounting by one-of-a-kind lap-joint flange concept (DN < 350/14″)
