Change of supply unit
The supply unit of ULTRAFLOW
®
54 can be changed from mains supply to battery or visa versa as the needs of the
supply company change. Thus, it can be an advantage to temporary change mains supplied meters to battery
supplied meters e.g. in case of buildings under construction where the mains supply can be unstable or
periodically missing.
Please note that the supply type of some ULTRAFLOW
®
sensors appears from the label. If the original supply type
is changed, it will no longer be in accordance with the label.
