AWWA C700-09

This standard covers the various types and classes of cold-water displacement meters with bronze main cases, in sizes 1/2 in. (13 mm) through 2 in. (51 mm), and the materials and workmanship employed in their fabrication. The displacement meters covered, known as nutating-disc or oscillating-piston meters, are positive in action because the pistons and discs displace or carry over a fixed quantity of water for each nutation or oscillation when operated under positive pressure. The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for cold-water meters--displacement type, bronze main case, including materials and design. The major revisions in this edition of C700-95 include the following: the format has been changed to reflect current AWWA standard style; an acceptance clause has been added (Sec. I.C) and the definitions of parties (Sec. 3) have been revised to approved wording; "soft" metric equivalents in the text and tables have been added; the rejection section has been revised (Sec. 5.1); appendix B, Future Revisions, has been deleted and an item on register markings has been added to Sec. 6.1 and to the foreword (Sec. III.A.15); and, a new appendix A, Bibliography, has been added.
