Hot commissioning

The hot commissioning is in most cases the last test of the UFM and can be witnessed by a
representative of the client and, if required, by an inspector of weights and measures for the
official sealing. Under this condition there is process gas in the pipe and a flow test is being
performed.  The  performance,  AGC  Levels/Limits  and  zero  flow  are  checked  again.  If
possible,  the  gas  flow  running  through  the  UFM  will  be  compared  to  another  flowmeter  in
the  line.  Most  UFM  are  calibrated  gas  flow  meters,  so  the  measured  value  is  reliable
without exception. Furthermore, the interaction with the flow computer can be tested.
