10.1 Technical data at a glance
10.1.1 Application
Application • Measuring the flow rate of fluids in closed piping systems.
• A minimum conductivity of ≥ 5 µS/cm is required for measuring; the minimum
conductivity required in the case of demineralised water is ≥ 20 µS/cm.
• Applications in measuring, control and regulation technology
Liner specific applications:
• Promag W (DN 25...2000):
– Polyurethane lining for applications with cold water and for slightly abrasive fluids.
– Hard rubber lining for all applications with water (especially for trinking water)
• Promag P (DN 15...600):
– PTFE lining for standard applications in chemical and process industries.
– PFA lining for all applications in chemical and process industries; especially for high
process temperatures and applications with temperature shocks.
• Promag H (DN 2...100):
PFA lining for all applications in chemical, process and food industries; especially for
high process temperatures, for applications with temperature shocks and for applica-
tions with CIP or SIP cleaning processes.
10.1.2 Function and system design
Measuring principle Electromagnetic flow measurement on the basis of Faraday’s Law.
Measuring system The measuring system consists of a transmitter and a sensor.
Two versions are available:
• Compact version: transmitter and sensor form a single mechanical unit.
• Remote version: transmitter and sensor are installed separately.
Transmitter :
•Promag 50
Sensor:
• Promag W (DN 25...2000)
• Promag P (DN 15...600)
• Promag H (DN 2...100)
