Installation space   

This value is calculated by the flow meter 

The  operator  must  mount  the  transducer 
according  to  the  transducer  spacing  displayed 
(ensure that the transducer spacing is measured 
precisely  during  installation).  The  system  will 
display  the  data  automatically  after  the  pipe 
parameter had been entered.
