Function enables user to set flowrate units.
Available units are:





Function enables user to set the name of user unit.
Maximum length is three letters.
Function enables user to set the conversion constant for
user unit. This constant is calculated as the ratio
between flowrate in [l/s] and flowrate in [user unit].
Setting enables user to change number of displayed
digits for flow measurement in main menu.
Function enables user to switch between "Positive"
and "Negative" flow direction (change the sign in
flowrate value).
Note: Flowmeters are working in both flow directions.
However standard calibration is made for positive
direction only.
Function enables user to set limit for suppressing low
flowrates. Available range is according to the nominal
diameter.
Note: All flowrates below this value will be displayed as
0. This setting is valid for display and all outputs.
Function enables user
seconds for moving average calculation. Available range
is between 1 and 20 seconds.
Note: Response time of flow meter to fast changing flow
can be compromised if large number of samples to
average is selected.
User can clear minimal and maximal measured flow.
Function enables user to set volume units.
Available units are:





Function enables user to set the name of user unit.
Maximal length is three letters.
Function enables user to set the conversion constant for
user unit. This constant is calculated as the ratio
between volume in [l] and volume in [user unit].
Setting enables user to change number of displayed
digits for volume measurement in main menu.
User can clear auxiliary or daily or positive and negative
measured volume.
