Recordall' Disc Meters <br />3 1 Badger Meter Lead -Free Bronze Alloy, Sizes 5/8", 5/8"° x 3/4 3/4"° & I" <br />NSF/A.NSi Standards 61 and 372 Certified <br />Model LP -5/8 5/8" x 3/4" Model 25-5/8", 5/8" x 3/4" Model 35-3/4" <br />Model 55-1" Model 70-1" <br />DESCRIPTION <br />The Recordall Disc Series meters meet or exceed the most recent revision <br />of AWWA Standard C700 and are available in a lead-free bronze alloy. The <br />meters comply with the lead-free provisions of the Safe Drinking Water Act, <br />are certified to NSF/ANSI Standards 61 and 372 (Trade Designations: MLP -LL, <br />M25 -LL, M35 -LL, M55 -LL, M70 -LL) and carry the NSF -61 mark on the housing. <br />All components of the lead-free bronze alloy meter (housing, measuring <br />element, seals, and so on) comprise the certified system. <br />Applications: For use in measurement of potable cold water in residential, <br />commercial and industrial services where flow is in one direction only. <br />Operation: Water flows through the meter's strainer and into the measuring <br />chamber where it causes the disc to nutate.The disc, which moves freely, <br />nutates on its own ball, guided by a thrust roller. A drive magnet transmits <br />the motion of the disc to a follower magnet located within the permanently <br />sealed register.The follower magnet is connected to the register gear train. <br />The gear train reduces the disc nutations into volume totalization units <br />displayed on the register or encoder face. <br />Operating Performance: The Recordall Disc Series meters meet or exceed <br />registration accuracy for the low flow rates (95%), normal operating flow <br />rates (100 ± 1.5%), and maximum continuous operation flow rates as <br />specifically stated in AWWA Standard C700. <br />Construction: Recordall Disc meter construction, which complies with <br />ANSI/AW WA standard C700, consists of three basic components: meter <br />housing, measuring chamber, and permanently sealed register or encoder. <br />The meter is available in a lead-free bronze alloy with externally -threaded <br />spuds. A corrosion -resistant engineered polymer material is used for the <br />measuring chamber. <br />Magnetic Drive: Direct magnetic drive, through the use of high-strength <br />magnets, provides positive, reliable and dependable register coupling for <br />straight -reading or AMR/AMI meter reading options. <br />Tamper -Proof Features: Unauthorized removal of the register or encoder <br />is inhibited by the option of a tamper detection seal wire screw, TORX® <br />tamper-resistant seal screw or the proprietary tamper-resistant keyed seal <br />screw. Each can be installed at the meter site or at the factory. <br />RDM-DS-00464-EN-02 AWWA (June 2014) <br />Maintenance: Badger Meter Recordall Disc Series meters are designed and <br />manufactured to provide long-term service with minimal maintenance. <br />When maintenance is required, it can be performed easily either at the meter <br />installation or at any other convenient location. <br />To simplify maintenance, the register, measuring chamber, and strainer can <br />be replaced without removing the meter housing from the installation. No <br />change gears are required for accuracy calibration. Interchangeability of <br />parts among like -sized meters and meter models also minimizes spare parts <br />inventory investment. The built-in strainer has an effective straining area of <br />twice the inlet size. <br />Connections: Tailpieces/Unions for installations of meters on various pipe <br />types and sizes, including misaligned pipes, are available as an option. <br />Meter Spud and Connection Sizes <br />Product Data Sheet <br />U8.• <br />Coupling <br />Tailpiece <br />Model <br />Size <br />x Laying <br />Nut and <br />Pipe <br />Designation <br />Length <br />gore Dia. <br />Spud <br />Thread <br />Thread <br />(NPT) <br />5/8" <br />x 7-1/2" <br />5/8" <br />3/4"(5/8") <br />1/2" <br />LP <br />5/8" x 3/4" <br />x 7-1/2" <br />5/8", 3/4" <br />1 " (3/4") <br />3/4" <br />5/8" <br />x 7-1/2" <br />5/8" <br />3/4"(5/8") <br />1/2" <br />25 <br />5/8" x 3/4" <br />x 7-1/2" <br />5/8,3/4" <br />1"(3/4") <br />3/4" <br />3/4" <br />x 7-1/2" <br />3/4" <br />1"(3/4") <br />3/4' <br />35 <br />3/4" <br />x 9" <br />3/4" <br />1"(3/4") <br />3/4" <br />3/4" x 1" <br />x 9" <br />3/4" <br />1-1/4"(1") <br />1" <br />55 <br />1" <br />x 10-3/4" <br />1" <br />1-1/4"(1") <br />1" <br />70 <br />1" <br />x 10-3/4" <br />1" <br />1-1/4"(1") <br />1" <br />Product Data Sheet <br />
