1.3.2 PULSE/UNIT
0.001...1000
Pulse per volume or mass unit of counter (setting in Fct. 3.11.2), which can be output via
one of the binary outputs. The maximum frequency for the pulse output (refer to Fct 1.3.1)
cannot be exceeded, even at maximum flow rate (full scale).

Example:
Final value Q
max
= 1200 L/h; volume unit of counter = Litre; pulse width = 100ms;
If the factor 1 is entered, 1 pulse/litre = 1200 pulses are generated in one hour at maximum
flow rate.
Number of max. permissible pulses:
