Set Offset
In the sub menu “Offset” it is possible to set the actual offset of the flow meter. This function should
just be used when FFU is completely filled with liquid and there is no flow.
A small offset change e.g. caused by variable temperatures is automatically done by the flow meter. It
is also possible to set the offset via the configurable digital inputs.
Language
The language of the display can be changed. Available languages are English and German.
Filter
The function „Filter“ determines the average determination of the analog output signal. Possible
configurations : Soft, Medium, Strong, Off
The analog output signal reacts faster to signal changes when average determination is soft. Where-
as the output signal reacts slower when average determination is strong.
Units
FFU is able to show actual flow or the volume in different unities. Following unities can be selected:
ml/s + l , Gal/min +Gal , l/min + l , l/min + m³.
Example: ml/s + l
The first letters correspond the unity of the flow value. The letters after the + correspond the unity of
the volume value.
Reset Counter
The volume counter of FFU can be reseted. Note, accidentally erased counter values are permanent
lost. After doing a reset the counting starts again at value „0“.
Basic Trim
This function makes sure that the flow meter is conforming to the media specific characteristics.
Through execute this function FFU runs a self configuration which optimises all important parameters.
This process may last app. 1 minute. To make sure the basic trim is correctly done the flow meter has
to be filled with liquid without a flow. When there is an error detected while doing the basic trim the
display shows “Error”. After successful finishing the function basic trim the display shows “Done”.
