ANSI/AWWA C713-10
This standard describes cold-water fluidic-oscillator meters with brass main cases in sizes 1/2 in. (13 mm) through 2 in. (50 mm) and the materials and workmanship employed in their fabrication. The bases for volume measurement is a transducer element that senses and utilizes fluidic oscillation rather than a moving measurement element, as required in cold-water volumetric meters.
