7.2. Pulse output OUT1
In any of the impulse modes, an impulse will be generated as soon as a defined (preset) fluid volume passes
through the meter sensor. Pulse width is fixed at 100 ms. For the duration of the impulse output is closed.
The following table shows the optimal choice of impulse numbers depending on the dimension of the
flowmeter.

7.3. Production data
The production label consist all the parameters that are set at the factory.
Constant K1
Pulse number
Numbers of samples
Suppressed flow
Constant of a sensor K1
– defines a basic calibration factor of a sensor
Pulse number
Numbers of samples
for averaging
– it stabilizes a flow value by flow drifting. It is possible to set it by
production on values 25, 50, 100, 150, 200, 250 of samples.
Suppressed flow
– it defines a flow area (symmetric around zero), where all outputs values are set on zero.
