10.1.1
Application
Liner specific applications:
• Promag S sensor (DN 15 to 600 / ½ to 24"):
– Polyurethane lining for applications using cold water and for abrasive fluids, e.g. for sludge with
particles smaller than 0.5 mm (<0.02 inch)
– Hard rubber lining for all water applications (especially for drinking water)
– Natural rubber lining for all water applications and for highly abrasive fluids, e.g. for sludge with
particles larger than 0.5 mm (>0.02 inch)
– PTFE lining for standard applications in the paper and food industries
– PFA lining for all applications in the paper and food industries; especially for high process
temperatures and applications with temperature shocks.
• Promag H sensor (DN 2to100 / 1/12 to 4"):
– PFA lining for all applications in the chemical, process and food industries; specially for high
process temperatures, with strong temperature shocks and applications with CIP and 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 flow measuring system consists of the following components:
• Promag 55 transmitter
• Promag S Sensor (DN 15 to 600 / ½ to 24"):
• Promag H sensor (DN 2 to 100 / 1/12 to 4"):
Two versions are available:
• Compact version: transmitter and sensor form a single mechanical unit.
• Remote version: transmitter and sensor are installed separately.
10.1.3
Input
Measured variable
• Flow rate (proportional to induced voltage)
• Conductivity (without temperature compensation)
Measuring range
• Flow rate: Typical v = 0.01 to 10 m/s (0.03 to 33 ft/s) with the specified measuring accuracy
• Conductivity s = 5 to 2000 mS/cm
not for sensors without reference electrode (Promag H, Promag S with brush electrodes)
Operable flow range
Flow rate: Over 1000 : 1
