The invention concerns a detection and display device for automatic service expresso coffee machine which automatically outputs and displays water or ground coffee doses according to the capacity of the filter-holder bowl engaged on the bowl-holder of the coffee machine. Detection and display are obtained by means of an actuator-detector system generating electric signals, such as one or more magnetic elements (5) mounted on filter-holder bowl (1) and a Hall effect detector (A) mounted on bowl-holder (11) of the coffee grinder or coffee machine.
