An acoustic flow meter assembly for pipes 26 or open channels, includes a frame 20 with a predetermined geometry. The frame has at least one user accessible port adapted to receive an interchangeable cartridge 44 which contains at least one acoustic transducer 46 to measure fluid velocity through said frame. The or each cartridge has an acoustic water level sensor (not indexed) so that the volumetric flow of water through the pipe or channel in which the meter is positioned can be measured and calculated. |
