The drinks preparation machine includes a pump for delivering the preparation fluid—generally water—into a brewing chamber, which receives the portion package, as well as a flow-meter for measuring the fluid flow into the brewing chamber. Machine electronics activate the pump and acquire the results of flow rate measurement, in order for example to switch off the pump after reaching a defined delivered fluid quantity. The electronics are configured to evaluate the measured flow rate and from this evaluation to make a differentiation between a first state 'brewing with an inserted portion package' and a second state “water throughflow without inserted portion package”, in order to detect the presence of a portion package in the brewing chamber.
