Meter Sizing Calculations for Marbrisa Phase 3
Summary:
The following document contains the supporting calculations for sizing the water laterals that
will be installed with phase Ill of the Marbrisa Development in Carlsbad Ranch PAS. The following page
summarizes the maximum demand possible that is anticipated for each building on the project. The
demand was calculated from the amount of cold water fixture units that will be installed in each building
and represents an absolute worst case scenario where all of the fixtures are turned on at once, as such
the maximum capacity of the meters was used in the tables attached to this report. The manufacturer's
information for the assumed water meters to be used has been included in this report. The tables from
the City of San Diego department of inspection for equating fixture units to GPM have also been
included in this report. Please note that the water meters that will service the Hotel 3 buildings are
oversized at this time, this is to account for future expansion that may occur in the future for this area.

Recordall® Turbo Series Meters
Models 160 (1-1/2"), 200 (2"), 450 (3"), 1000 (411),
2000 (6"), 3500(8"), 5500(10"), & 6200(12");
NSF/ANSI Standards 61 and 372 Certified
DESCRIPTION
Recordall Turbo Series meters meet or exceed the most recent
revision of AWWA Standard C701 Class II Standards and are
available in a lead-free bronze alloy for sizes 1-1/2" through ion
and cast iron for 12" meters. Turbo Series meters comply with the
lead-free provisions of the Safe Drinking Water Act. Sizes 1-1/2"
through 10" meters are also certified to NSF/ANSI Standards 61
and 372 (Trade Designation: Turbo Series LL-NS) and carry the
NSF-61 mark on the housing. All components of the lead-free alloy
meter (housing, measuring element, seals and so on) comprise the
certified system.
Models 160 through 6200 are designed for 1-1/2" through 12"
applications. These meters feature:
Direct coupled turbine based on an exclusive "floating rotor"
design that reduces bearing friction—and associated wear and
tear.
Low pressure loss for improved system efficiency.
Exceptional registration accuracy across low flow rate, normal
operating flow rate and maximum continuous operation flow.
Permanently sealed, tamper-resistant register or encoder.
Integral strainer option for sizes 1-1/2" through 4" help protect
your system from damaging debris and related downtime.
Meters and encoders are compatible with Badger Meter
AMR/AMI meter reading systems and other approved reading
technologies.
Applications: Recordall Turbo Series meters are designed for
cold water, commercial and industrial applications where flows
are consistent medium to high flows. Applications include hotels,
apartment buildings, irrigations centers and manufacturing
and processing plants. Turbo Series meters help reduce day-to-
day maintenance costs while delivering accurate and efficient
performance.
Operation & Performance: Direct magnetic drive is achieved
when the magnet carrier is driven by a gear train coupled to
the rotor. The gear train consists of two sets of gears connected
by a vertical transmission shaft. One gear set is at the magnet
carrier, the other is a worm gear set at the rotor shaft. When
water flows into the Turbo Series meter measuring element, it
contacts the multi-vaned rotor. The resulting rotor rotation is
then transmitted by magnetic coupling to a sealed register or
encoder. The direct magnetic drive is built to provides a reliable
meter-to-registration coupling.
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 seat screw or the proprietary
tamper-resistant keyed seal screw. Each can be installed at the
meter site or at the factory.
Construction: The Recordall Turbo Series meter is constructed in
compliance with ANSI and AWWA C701 standards. It consists of
the following basic components: meter housing, interchangeable,
unitized measuring element and permanently sealed direct
reading registers or encoders.
The measuring element consists of the transmission coupling,
rotor, inlet and outlet straightening vanes with nose cones, and
calibration ring assembly. The unique inlet and outlet straightening
vanes minimize swirl from piping arrangements upstream as well
as downstream.
A strainer is recommended to help ensure optimal flow
conditioning and protection for the measuring element. An
integral strainer is available as an option for 1-1/2" through 4"
meter sizes. The stainless steel strainer is built into the inlet end and
includes a removable cover plate to permit easy access for routine
cleaning. External strainers are available in sizes 2" through 12".
To simplify maintenance, the registers or encoders and measuring
elements can be removed without removing the meter housing.
Interchangeability of certain parts between meters also minimizes
spare parts inventory investment.
Meter Installation: The meter is designed for installations where
flow is in one direction only. Companion flanges for installation of
meters on various pipe types and sizes are available in cast iron or
NL bronze as an option. See the Recordall Turbo Series Meters User
Manual for specific instructions.

DESCRIPTION
The Recordall Disc Series meters meet or exceed the most recent revision
of AWWA Standard C700 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, M35-1.1., M55-LL, M70-1.1.) 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 C700.
Construction: Recordall Disc meter construction, which complies with
ANSI/AWWA standard C700, 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 AMR/AMI 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.
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.
