A combination of a flow meter and printed circuit board or flex-print for a liquid food or a beverage preparation machine, which board or flex-print is rigidly connected to the flow meter. In one embodiment, and by way of example only, the method includes thermally spraying a first material onto an outer surface of a sacrificial substrate to form the foil component inner portion, where the first material includes a solid film lubricant, and the outer surface has a shape that is complementary to the inner surface of the foil component. The receiver in the vehicle within the range of the transmitter decodes the received signal and activates the contained alarms to alert the occupants of the vehicle of the approaching train and the condition of the warning system. FRF and highly purified FRF can also be used in a controlled release, targeted release and other specialized delivery systems, as well as in food and cosmetics formulation. The second local client terminal downloads the operating system from the first local client terminal in response to the first response signal.
