Field of application
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.
The bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity
Fully suitable for standard applications in the water and wastewater industry.
