11.1 Adjustment

Adjust the output following the
installation of the reed chain and after
the connection to the supply voltage
using an external measuring
instrument.
This is carried out with the two
trimmer potentiometers accessible
from the side.
Compensation between the non-linear
scaling of the flowmeter and the linear
output signal of the flow data sensor
must be performed by adjusting,
preferably between 20 % and 80 % of
the flow rate.
Here 20% corresponds to 7.2mA and
80% to 16.8mA.
 Connect the ammeter and the
respective voltage supply to the
flow data sensor
 Allow 20% of the flow to pass the
DFM
 Set the min. trimmer
potentiometer (3) such that the
corresponding current (7.2mA) is
shown in the ammeter
 Allow 80% of the flow to pass the
DFM
 Set the max. trimmer
potentiometer (3) such that the
corresponding current (16.8mA)
is shown in the ammeter
 Check the values at 20% and
80% several times and repeat
the adjustment, if required
