A system for ascertaining fresh water consumption by an, in particular, commercial dishwasher (1) or a component thereof. The system includes a container (12, 22) for temporarily storing liquids, wherein the container (12, 22) has a liquid inlet (25), which can be flow-connected to a fresh water source if required, and a liquid outlet (23), which can be flow-connected to a freshwater consuming means, in particular a freshwater consuming means of the dishwasher (1), if required. The system further includes at least one pressure sensor (B3, B4) for detecting an, in particular, hydrostatic pressure in the container (12, 22), and an evaluation device which is designed to ascertain a fresh water volume flow into the container (12, 22) depending on at least one output value of the at least one pressure sensor (B3, B4).
A system for ascertaining fresh water consumption by a commercial dishwasher (1) or a component thereof, wherein the system comprises:
The system as claimed in 1, wherein the system includes a learning mode in which an actual value of a fresh water volume flow via the liquid inlet (25) into the container (12, 22) is ascertained or can be ascertained, in a state in which an actuable valve (Y1) which is associated with the liquid inlet (25) is in its open valve position.
A method for ascertaining fresh water consumption by a commercial dishwasher (1) or a component thereof, wherein a hydrostatic pressure in a container (12, 22) for temporarily storing liquids is detected with the aid of a pressure sensor (B3, B4), and wherein a fresh water volume flow into the container (12, 22) is ascertained depending on at least one output value of the at least one pressure sensor (B3, B4).
