Recordall® Cold Water Bronze Disc Meter
Size 5/8, 5/8 x 3/4" (DN 15mm) Model LP
NSF/ANSI Standard 61 Certified, Annex G
DESCRIPTION
Badger Meter offers the Recordall Disc meter in a bronze lead-free alloy. The
Lead-Free Alloy (Trade Designation: MLP-LL) meter has been certified to
comply with NSF/ANSI Standard 61, Annex G and carries the NSF-61 Mark on
the housing. All components of the Lead-Free Alloy meter, i.e., disc, chamber,
housing, seals, etc. 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 dial face.
OPERATING PERFORMANCE: The Badger Meter Recordall Disc 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 by AWWA Standard C700.
CONSTRUCTION: Badger Meter Recordall Disc meter construction, which
complies with ANSI/AWWA standard C700, consists of three basic components:
meter housing, measuring chamber, and permanently sealed register. The
water meter is available in a Bronze Lead-Free Alloy with externally-threaded
spuds. A corrosion-resistant engineered polymer material is used for the
measuring chamber.
To simplify maintenance, the register, measuring chamber, and liner/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 also minimizes spare parts inventory investment.
The built-in strainer has an effective straining area of twice the inlet size.
MAGNETIC DRIVE: Direct magnetic drive, through the use of high-strength
magnets, provides positive, reliable and dependable register coupling for
straight-reading, remote or automatic meter reading options.
SEALED REGISTER: The standard register consists of a straight-reading
odometer-type totalization display, 360° test circle with center sweep hand
and flow finder to detect leaks. Register gearing consists of self-lubricating
engineered polymer gears to minimize friction and provides long life.
Permanently sealed; dirt, moisture, tampering and lens fogging problems are
eliminated. Multi-position register simplifies meter installation and reading.
Automatic meter reading systems are available for all Recordall Disc meters.
All reading options are removable from the meter without disrupting water
service.
TAMPER-PROOF FEATURES: Customer removal of the register to obtain
free water can be prevented when the optional tamper detection seal wire
screw or TORX® tamper resistant seal screw is added to the meter. Both can
be installed at the meter site or at the factory.
MAINTENANCE: Badger Meter Recordall Disc 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. As an alternative to repair by
the utility, Badger Meter offers various maintenance and meter component
exchange programs to fit the needs of the utility.
CONNECTIONS: Tailpieces/Unions for installations of meters on various
pipe types and sizes, including misaligned pipes, are available as an option.
