VEGA VEGAPULS 61 (≥ 2.0.0 - ≥ 4.0.0) Foundation Fieldbus Approval according to LPR radio standard - Manual (Page 79)

The function block "Integrator" integrates a continuous input signal over the time and sums the results
of an impulse input block. It is used as a totalizer up to a reset or as a subtotalizer up to a reference
point at which the integrated and accumulated value is compared with the default values. When these
default values are reached, digital output signals will be outputted. The integration function is carried
out upwardly starting with zero and downwards with a default value. Two flow values are also
available so that the net flow volume can be calculated and integrated. This can be used for
calculation of volume and mass changes in the vessel or for optimisation of flow controls.
