  • The Electromagnetic Flow Measuring Principle

Promag L is the versatile standard sensor for the water industry with a lap-joint flange concept for flexible installation independent of the orientation of the pipe flange pitch diameter. Combined with the Promag 53 transmitter with touch control, 4-line display and extended functionality like software options for filling and dosing, electrode cleaning or advanced diagnostics, Promag 53L offers highest accuracy in the most complex and demanding measuring tasks.


  • Reduced installation costs – flexible mounting by one-of-a-kind lap-joint flange concept (DN < 350/14")

  • Energy-saving flow measurement – no pressure loss due to cross-section constriction

  • Quality – software for filling & dosing, density, electrode cleaning and also advanced diagnostics

  • Easy calculation – bidirectional totalizers

  • Automatic recovery of data for servicing

  • Maintenance-free – no moving parts

Field of application

  • The measuring principle is virtually independent of pressure, density, temperature and viscosity

  • Fully suitable for standard applications in the water and wastewater industry.
