25 1 25
99.99 1 99.99
1.50 1 1.50 (1 / 2)
1.25 1 1.25 (1 / 1 / 1 / 2)

* Explanation of the conversion ratio
With a factor of 1 ... 1 stroke is executed per 1 pulse.
With a factor of 2 ... 2 strokes are executed per 1 pulse
With a factor of 25 ... 25 strokes are executed per 1 pulse
** Explanation of step-down
With a factor of 1 ... 1 stroke is executed per 1 pulse.
With a factor of 0.5 ...1 stroke is executed after 2 pulses.
With a factor of 0.1 ...1 stroke is executed after 10 pulses.
With a factor of 0.75 ...1 stroke is executed once after 2 pulses,
then 1 stroke is executed twice after 1 pulse,
and then again 1 stroke after 2 pulses etc.
Table of examples
If a remainder is obtained when dividing by the factor, then
the unit adds the remainders together. As soon as this sum
reaches or exceeds "1", the pump executes an additional
stroke. Therefore on average during the metering operation,
the resultant number of strokes precisely matches the factor.
Using "Pulse Control" you can ideally adapt the pump to the relevant
process, for example in conjunction with contact water meters.
