7 - PULSE OUTPUT
One transistor output is available as scaled pulse output according to the accumulated total
.
DECIMALS
7.1 Sets the decimals for the pulses per 7.3
WIDTH OF PULSE
7.2
The pulse width determines the time that the transistor will be switched; in other words
the pulse length. The minimum time between the pulses is as long as the selected period
time.
Pulse widths are between 5 m sec to 1 sec at 5 m sec this is a frequency of 100Hz
Note: If the frequency should go out of range - when the flow rate increases for
example - an internal buffer will be used to "store the missed pulses": As soon as
the flow rate reduces again, the buffer will be "emptied".
It might be that pulses will be missed due to a buffer-overflow, so it is advised to
program this setting within it's range.
PULSE PER
7.3
According to the measurement unit settings for total, a pulse will be generated every X-
quantity. Enter this quantity here while taking the displayed decimal position and meas-
uring unit into account. i.e. set to 00000.10 = 10 pulses per unit of measure selected

The FPD3100-D-A unit can only accept a reed switch input, this sensor has been se-
lected as the most common sensor and requires very little power with small effect on bat-
tery life.
The reed switch is not polarity conscious so the reed switch wires can be connected in
any order to pins 1 and 2
