5.4.1 Connection of the FlexPower unit
Optionally, beside an internal or external battery, the WATERFLUX3070 can be connected to an
external FlexPower unit for mains power and/or DC power operation with battery back-up.
The input power for the KROHNE FlexPower can be realized by connection to an AC / DC supply
source
•
AC mains supply source : 110...230 V AC - 50/60 Hz
•
DC supply source : 10...30 V DC
Automatically a start-up routine is followed, when the WATERFLUX 3070 with FlexPower is
connected properly to a live AC and/or DC supply. First the DC input is checked and if present and
AC/DC converter active, the power source is DC. When AC power is present and AC/DC converter
active, the power source is AC/DC. If both are not available (interrupted) the internal dual D-cell
battery pack ( 3.6V - 38 Ah) automatically takes over the power supply.
To save energy, the WATERFLUX 3070 will automatically switch to the low power consuming battery
backup mode and will continue to totalize volumes but temporarily stop to transfer the data.
The FlexPower unit is IP68 rated and totally sealed and potted to prevent ingress of water.
Therefore the integrated batteries cannot be changed.

DC power output of the FlexPower can easily be connected with the cable assembly that is
delivered with the FlexPower unit. The UTS snap-on connector of the cable fits in only one way to
the female connector on the FlexPower unit.
