Actual settings: Digital output

Actual settings: Analog output
The analog output represents the actual measured value. This analog output can be modified in many
ways.
You can see the actual settings on this card.

– Option pulse
In this mode the FMT200-ECO2 (Sensyflow
eco2) is counting the flow which has passed the
sensor. Value represents the totalized flow,
equivalent to one impulse of adjusted length with
polarity HIGH or LOW.
– Option frequency
In this operation mode the momentaneous mea-
suring value is represented by an equivalent fre-
quency. The lower limits of the frequency means
zero flow, the upper limit 100% of the adjusted
measuring range.
– Option switch
In this mode a contact will be closed or opened
if the measuring value exceeds the adjusted lim-
its. Polarity can be HIGH or LOW.

Range full scale value:
actual full scale value (adjustable).
Upper range value:
maximum measuring range, that means the instru-
ment is calibrated up to this point. It is not possible
to select ranges higher than this value.
Measured value:
actual measurement result shown in the chosen
unit.
Selected output:
Which electrical analog output is active?
Analog output:
actual measuring value as analog signal (mA or V).
Output at error:
FMT200-ECO2 signalizes an error at the analog
output.
Filter factor:
time constant of the damping.
Offset suppression:
Measuring values smaller than the adjusted one
will be shown as zero flow.
