<p>A flow meter is disclosed which comprises a flow pipe for measuring consumption of a fluid passing there-through irrespective of flow direction. The flow pipe comprises a central segment and two edge segments, each located at a different side of the central segment so that the three segments form a continuous passage for the passing fluid. The flow meter is configured to enable flow of the fluid via an aperture to/from the central segment from/to a respective edge segment, while each of the edge segments has an inner diameter greater than that of the respective aperture enabling the flow from/to that edge segment to/from the central segment. The flow meter further comprises three pressure meters, each configured to enable measuring static pressure of the fluid flowing through a respective segment, thereby enabling to determine forward and backward fluid flows through the flow pipe.</p> |
