9  Super User Mode 

The Super User Mode gives you the opportunity for experimental work. In this 
operational mode, 

YOU

, not FLUXUS, will be responsible and must decide: 

  upon the observance of the parameter ranges, characterised by physical and 

specification limits; 

 

upon the correctness of data inputs; 

  upon the meaningfulness of measured values for measurements performed under 

conditions which are outside the specification. 

 

YOU

 will need to take care that the measuring results are free from contradictions. In 

other words: FLUXUS operates in Super User Mode without observing pre-set 
standard parameters and limit values which normally guide you through the complexity 
of ultrasonic flow measurement. 

 
 

9.1  Activation/Deactivation of the Super User 

Mode
