Recordall Disc Meters LeadFree Bronze Alloy, Sizes /8", /8" x 3/4", 3/4" & " NSF/ANSI Standards 6 and 372 Certified LP /8", /8" 3/4" 2 /8", /8" 3/4" 3 3/4" " 7 " DESCRIPTION The Recordall Disc Series meters meet or exceed the most recent revision of AWWA Standard C7 and are available in a leadfree bronze alloy. The meters comply with the leadfree provisions of the Safe Drinking Water Act, are certified to NSF/ANSI Standards 6 and 372 (Trade Designations: MLPLL, M2LL, M3LL, MLL, M7LL) and carry the NSF6 mark on the housing. All components of the leadfree bronze alloy meter (housing, measuring element, seals, and so on) comprise the certified system. Applications: For use in measurement of potable cold water in residential, commercial and industrial services where flow is in one direction only. Operation: Water flows through the meter s strainer and into the measuring chamber where it causes the disc to nutate. The disc, which moves freely, nutates on its own ball, guided by a thrust roller. A drive magnet transmits the motion of the disc to a follower magnet located within the permanently sealed register. The follower magnet is connected to the register gear train. The gear train reduces the disc nutations into volume totalization units displayed on the register or encoder face. Operating Performance: The Recordall Disc Series meters meet or exceed registration accuracy for the low flow rates (9%), normal operating flow rates ( ±.%), and maximum continuous operation flow rates as specifically stated in AWWA Standard C7. Construction: Recordall Disc meter construction, which complies with ANSI/AWWA standard C7, consists of three basic components: meter housing, measuring chamber and permanently sealed register or encoder. The meter is available in a leadfree bronze alloy with externallythreaded spuds. A corrosionresistant engineered polymer material is used for the measuring chamber. Magnetic Drive: Direct magnetic drive, through the use of highstrength magnets, provides positive, reliable and dependable register coupling for straightreading or AMR/AMI meter reading options. TamperProof Features: Unauthorized removal of the register or encoder is inhibited by the option of a tamper detection seal wire screw, TORX tamperresistant seal screw or the proprietary tamperresistant keyed seal screw. Each can be installed at the meter site or at the factory. Maintenance: Badger Meter Recordall Disc Series meters are designed and manufactured to provide longterm service with minimal maintenance. When maintenance is required, it can be performed easily either at the meter installation or at any other convenient location. To simplify maintenance, the register, measuring chamber, and strainer can be replaced without removing the meter housing from the installation. No change gears are required for accuracy calibration. Interchangeability of parts among likesized meters and meter models also minimizes spare parts inventory investment. The builtin strainer has an effective straining area of twice the inlet size. Connections: Tailpieces/Unions for installations of meters on various pipe types and sizes, including misaligned pipes, are available as an option.
