Product description

Electromagnetic Flow Measuring System

Flow rate measurement of liquids with solids content or inhomogeneous liquids


Your benefits

Promag measuring devices offer you cost-effective flow measurement with a high degree of accuracy for a wide range of process conditions.


The Proline transmitter concept comprises of:

  • High degree of efficiency due to the modular device and operating concept
  • Software options for: electrode cleaning, advanced diagnostics, calculation of mass flow and solids content

The robust Promag S sensors offer:

  • Universal devices, even for difficult fluids
  • Excellent accuracy and repeatability
  • High resistance to abrasion thanks to industry-optimized linings and measuring electrodes
  • Optimum operational safety due to advanced, permanent self-diagnosis
  • Simple installation and commissioning
  • Insensitive to vibration
  • No pressure loss

Field of application

Electromagnetic flowmeter for bidirectional measurement of liquids with a minimum conductivity of ≥5 μS/cm - in particular fluids with solids, and fluids which are abrasive, inhomogeneous or tend to build-up, for example:


  • Chemical/mechanical pulps, paper pulp or wood pulp with solids contents up to 15 Vol.-%
  • Fruit mashes, fruit concentrates and final products (salad dressings, soups with vegetable pieces)
  • Slurries containing high amounts of sand or stone with an abrasive effect, e.g. ore slurry or mortar
  • Chemically inhomogeneous fluids (e.g. additives)
  • Thick wastewater sludges
  • Flow measurement up to 9600 m³/h (42 267 gal/min)
  • Can be used up to +180 °C (+356 °F) and max. 40 bar (580 psi)
  • Fitting lengths as per DVGW/ISO

Application-specific linings and electrodes:

  • Natural rubber, hard rubber, polyurethane, PTFE or PFA linings
  • Flat, bullet nose, neck, bow or brush electrodes

Approvals for hazardous area:

  • ATEX, FM, CSA
