ABSTRACT:
An apparatus is disclosed for measuring the rate of flow of a fluid or the volume of the fluid flowing past a point. The apparatus includes a first transducer device for measuring a fluid level upstream of a weir and a second transducer device for sensing and decoding an optically encoded Gray-scale disc rotated by the first transducer device to an angular position corresponding to the level of the fluid. The disc is provided with indicia thereon proportional to flow rates and corresponding to different fluid levels. The decoded signals obtained from the disc represent the rate of flow of the fluid. These signals are then integrated to indicate the volume of the fluid flowing past a point for actuating a fluid sampler or a recording device.
