The head line of the display shows the measuring unit
ml/min
and after a space the unit for the accumulated
value as
l
for liter. In the middle line the flow in ml/min and in the bottom line the accumulated value in liter
is shown.
For high accuracy measurement we recommend to rinse the flow sensor with 100 ml/min RO water for 15
min.

Values up to 180 can be selected. The selected value represents the time in seconds, during the values are
averaged.
To avoid malfunction of the sensor, please make
sure to connect fluid correctly the sensor. The
