Recordall® Combo Meter

Lead-Free Bronze Alloy, Size 8"
NSF/ANSI Standards 61 and 372 Certied

DESCRIPTION

The Badger Meter Recordall Combo meters meet or exceed the
most recent revision of AWWA Standard C700 and are available
in a lead-free bronze alloy. The Combo meters comply with the
lead-free provisions of the Safe Drinking Water Act, are certified to
NSF/ANSI Standards 61 and 372 (Trade Designation: Combo-01)
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.

The Combo meter combines two metering technologies in one
innovative package. A positive displacement chamber measures
low flow, while a turbine chamber records high flow.

The 8-inch Combo meter features:

• Spring-loaded check valve to facilitate one-way water flow
through appropriate measurement chambers, in line
with demand.

• Permanently sealed, tamper-resistant register or encoder.

• Meters and encoders that are compatible with Badger Meter
AMR/AMI systems and other approved reading technologies

Badger Meter ORION® and GALAXY® AMR/AMI meter reading
systems are available for all Combo meters. Itron® ERT reading
systems are also available. An optional summator can be provided
as an integral part of the register assembly. All register options are
removable from the meter without disrupting water service.

TAMPERPROOF FEATURES

Unauthorized removal of the register or encoder is inhibited by
the use of an optional 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.

Rotor and disc movements are transmitted by magnetic drive
couplings to individual register odometers. The direct magnetic
drive provides a positive, reliable and dependable register coupling
for straight-reading or remote reading options. The self-lubricating
thermoplastic register gearing is designed to minimize friction and
provide long life.

OPERATING PERFORMANCE

The Recordall Combo meter meets or exceeds registration accuracy
for low, normal operating, maximum continuous operation, and
changeover flow rates as specified in AWWA Standard C702.

CONSTRUCTION

The Recordall Combo meter’s construction complies with ANSI and
AWWA C702 standards. It consists of a stainless steel spool with
bypass port, turbine measuring chamber, a check valve with bypass
piping, a disc measuring chamber, valve assembly, and sealed
direct reading registers. To simplify maintenance, the registers and
measuring elements can be removed without removing the meter
housing from the line.

APPLICATIONS

Use the Recordall Combo meter for measuring potable cold
water in commercial and industrial applications where flow is in
one direction only. The meter is an ideal choice for facilities that
experience rapid and wide fluctuations in water demand, such as
hospitals, universities, residential complexes and manufacturing or
processing facilities.

OPERATION

As water enters the meter at low flow rates, a spring-loaded
check valve on the downstream side holds the clapper assembly
in a closed position. Water is diverted through a bypass to the
disc measuring chamber. As the flow rate increases, a pressure
differential is created that opens the check valve and allows water
to flow through the turbine chamber. A small amount of water will
continue to flow through the bypass when the clapper assembly is
fully open.

RCO-DS-00079-EN-02 (October 2013)

METER INSTALLATION

The meter is designed for installations where flow is in one
direction only. A separate strainer is required to ensure optimum
flow conditioning and protection of the measuring element.
Companion flanges for installation of meters on various pipe types
and sizes are available in cast iron or NL bronze as an option.

REGISTERS / ENCODERS

Standard—Sweep-Hand Registration

The standard register is a straight-reading, permanently sealed magnetic drive register. Dirt, moisture, tampering and lens fogging
problems are eliminated. The register has a six-odometer wheel totalization display, 360° test circle with center sweep hand, and flow finder
to detect leaks. Register gearing is made of self-lubricating engineered polymer, which minimizes friction and provides long life. The multi­position register simplifies meter installation and reading. The register capacity is 100,000,000 gallons (10,000,000 ft3, 1,000,000 m3).

Optional—Encoders for AMR/AMI Reading Solutions

AMR/AMI solutions are available for all Recordall Combo meters. All reading options can be removed from the meter without disrupting
water service. Badger Meter encoders provide years of reliable, accurate readings for a variety of applications and are also available pre­wired to Badger Meter approved AMR/AMI solutions. See details at www.badgermeter.com.
