scope:

This standard describes cold-water fluidic-oscillator meters with brass main cases in sizes ½ in. (13 mm)* through 2 in. (50 mm), and the materials and workmanship employed in their fabrication. The basis for volume measurement is a transducer element that senses and utilizes fluidic oscillation rather than a moving measurement element, as required in traditional cold-water volumetric meters.

Purpose

The purpose of this standard is to provide the minimum requirements for cold-water meters-fluidic-oscillator type, including materials and design.
