Recorda I ® D isc M eters Badger Meter Lead-Free Bronze Alloy, Sizes S/S'~ S/S" x 3/4'~ 3/4" & ," NSF/ANSI Standards 61 and 312 Certified Model LP-SI8'~ 5/8" x 3/4" Model 2S-SI8'~ 5/8" x 3/4" Model 35-3/4" Model 55-1" DESCRIPTION The Recordall Disc Series meters meet or exceed the most recent revision of AWWA Standard ClOO and are available in a lead-free bronze alloy. The meters comply with the lead-free provisions of the Safe Drinking Water Act, are certified to NSF/ANSI Standards 61 and 372 (Trade Designations: MLP-LL, M25 -LL, M35-LL, M55-LL, M70-LL) and carry the NSF-61 mark on the housing. All components of the lead -free 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 (95%), normal operating flow rates (100 ± 1.5%), and maximum continuous operation flow rates as specifically stated in AWWA Standard ClOO. Construction: Recordall Disc meter construction, which complies with ANSIIAWWA standard ClOO, consists of three basic components: meter housing, measuring chamber, and permanently sealed register or encoder. The meter is available in a lead -free bronze alloy with externally-threaded spuds . A corrosion-resistant engineered polymer material is used for the measuring chamber. Magnetic Drive: Direct magnetic drive, through the use of high-strength magnets, provides positive, reliable and dependable register coupling for straight-reading or AMRIAMI meter reading options. Tamper-Proof Features: Unauthorized removal of the register or encoder is inhibited by the option of a tamper detection seal wire screw, TORX · tamper-resistant seal screw or the proprietary tamper-resistant keyed seal screw. Each can be installed at the meter site or at the factory. RDM-DS-00464-EN-02 AWWA (June 2014) Model 70-1" Maintenance: Badger Meter Recordall Disc Series meters are designed and manufactured to provide long-term 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 like-sized meters and meter models also minimizes spare parts inventory investment. The built-in 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.
