invention for instance the conduit between the tank 1 and the water outlet 11 may further comprise a temperature sensor and if the machine is a beverage preparation machine a holder for receiving a beverage brewing product e g coffee or tea which may be placed in the holder in the form of loose material e g coffee granules or tea leaves or packaged in a pad capsule or other suitable package other embodiments are equally suitable the controller 5 is arranged to provide the pump 3 with an energizing signal 8 the energizing signal 8 is defined by the controller 5 to ensure that the water presented at the water outlet 11 has the required properties in particular flow rate control of the flow rate may also be important to ensure that the heating means 4 is capable of appropriately adjusting the temperature of the water in case of an excessive flow rate the heating means 4 may have insufficient capacity to sufficiently adjust this temperature the flow rate may also play an important role in the brewing or dissolution of the food ingredient products for instance if the machine is a beverage preparation machine the control of the flow rate.
