ANSI AWWA C702:2001 pdf download.COLD -WATER METERS- COMPOUND TYPE.
ANSI AWWA C702 describes the various types and classes of cold—water compound-type meters in sizes 2 in. (50 mm) through 8 in. (200 mm) and the materials and workmanship used in their fabrication. Compound meters shall consist of a combination of a turbine-type, main-line meter for measuring high rates of flow and a bypass meter of an appropriate size for measuring low rates of flow. The compound meter shall have an automatic valve mechanism for diverting low rates of flow through the bypass meter.
Sec. 1.2 Purpose
The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for cold—water meters—compound type, including materials and design.
Sec. 1.3 Application
ANSI AWWA C702 can be referenced in specifications for purchasing and receiving cold—water meters—compound type. ANSI AWWA C702 can be used as a guide for manufacturing this type of meter. The stipulations of ANSI AWWA C702 apply when this document has been referenced and then only to cold- water meters- compound type.
ANSI AWWA C702 references the following documents, which form a part of ANSI AWWA C702 to the extent specified herein. In any case of conflict, the requirements of ANSI AWWA C702 shall prevail.
