Abstract (en)

A method for controlling a peristaltic pump for the supply of fluid products comprises the following stages in combination with one another: calibration of the peristaltic pump by calculating a series of pairs of values each formed by the volume of product supplied (V i ) and the number of strokes of the rotor (X i ) needed to obtain this volume, calculation, by an interpolation operation, of the intermediate values with respect to each pair of values (V i , X i ) obtained at the calibration stage, calculation of a predetermined volume to be supplied (V), searching for the closest interpolated value (V dispensed ) and calculation of the number of corresponding strokes (X dispensed ), and actuation of the actuator means to carry out the supply of the required volume of fluid product.
