NOTE 1
The water flow in the mixers is approximately 10 c.c. per second and it is given as a guideline, as there are
many variables that can affect the accuracy.
The liquid dose is determined by the flow-meter pulse counting (volumetric counter).
Both versions (Instant and Espresso) use an electromechanical vibration pump (with the espresso boiler) for
the water flow, therefore the liquid dose in both versions is measured in flow-meter pulses
(
fmp
).
NOTE 2
To be noted that the number of pulses does not change in a linear manner (i.e. double the amount of water
does not correspond to double the number of pulses), however the counter varies the accuracy according to
the water flow velocity, and namely:
For espresso coffee it is reduced considerably because of the coffee compress reaction that slows down the
water flow, while it is accelerated in the instant drinks selections, since there are no obstructions to the
water flow. Therefore, in the event of changing the doses set at the factory, some measurements must be
made using measuring containers.
