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
