6.3
Decimals
In this screen the number of decimals for the flow rate indication can be selected.
To select the number of decimals it must be taken into account that the instrument has 5
digits for flow rate indication. If two decimals have been selected, these will be seen whilst
the flow rate is not higher than 999.99. Above this value the indication will automatically
change to one decimal, and when the flow rate is higher than 9999.9 the indication will be
done without decimals.
If one decimal is selected, the flow rate indication will have a maximum of one decimal.
If indication without decimals is selected, the flow rate will always be shown without
decimals.
For the selection of the flow rate units and the number of decimals it must be taken into
account that an indication with an excess of decimals may give the sensation of instability of
the reading. As a general rule it can be considered that the reading should not have more
than a total of 5 digits (integer + decimals).

Flow rate
This screen displays a submenu to modify different aspects related to flow reading, such as
cut off, flow reversal, filtering and offset.
6.4.1
Cut off
A cut off flow rate can be programmed, that means, the flow rate below which the flow rate
indication will be zero. This can avoid reading errors in the lower zone of the scale. The
maximum allowed value for the cut off is the equivalent to a liquid velocity of 1 m/s.
6.4.2
Reversed flow rate
The CU100 is a bi-directional flowmeter. The flow rate changes its sign automatically when
the flow is reversed. If after the flowmeter has been installed it is necessary to reverse the
flow rate sign, in this screen it can be done selecting the option "REVERSAL– Yes".
