Field of application

Promag S is the specialist for inhomogeneous, abrasive and corrosive fluids. The robust sensor design, featuring industry-optimized liners, enables its use in most challenging surroundings and metering jobs such as sewage treatment, pulp and paper production or in the primaries and metals industry. Due to its high-performance transmitter, Promag 55S not only measures flow reliably, but also calculates solids content at low maintenance requirements.

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

  • Ideal for the most demanding applications with high solids content and high abrasion.

Device properties

  • Intensified coil system

  • Large range of liners

  • Solids content up to 80 % by weight

  • 4-line backlit display with touch control

  • Two switch outputs

  • HART, PROFIBUS PA/DP, FOUNDATION Fieldbus

Benefits

  • Superb signal stability due to unique signal processing

  • Maximum safety – industry-optimized measuring electrodes and linings

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

  • Maintenance-free – no moving parts

  • Highest performance – with integrated solids measurement for demanding fluids

  • Highest safety – integrated electrode cleaning

  • Automatic recovery of data for servicing
