10 Technical data
10.1 Technical data at a glance
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 for monitoring
processes, filling and batching operations.
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
– Remote version
