Recordall® Compound Series Meter
Cold Water Bronze & Lead-Free Alloy Meter
NSF/ANSI Standard 61 Certified, Annex G
DESCRIPTION
Badger Meter Recordall® Compound Series meters combine two
metering technologies in one innovative package. A positive
displacement chamber measures low flow, while a turbine
chamber records high flow.
Offered in four sizes, the Compound Series meter features:
•t
Patented design that eliminates the need for a trigger valve and
maintains crossover accuracy.
•t
Sealed, multi-position register that protects against dirt,
moisture and tampering—and eases installation and reading.
•t
Straight-reading odometer-type totalization display, 360° test
circle with center sweep hand and flow finder to detect leaks.
•t
Compatibility with a range of automatic meter reading systems.
Badger Meter ORION® and GALAXY® AMR/AMI meter reading
systems are available for all Compound Series 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.
APPLICATIONS
Use the Recordall Compound 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.
Compound Series meters are available in cast bronze or a lead-free
alloy and comply with NSF/ANSI Standard 61, Annex G. The meters
carry the NSF-61 Mark, Trade Designation: Compound Series LL-NS.
OPERATION & PERFORMANCE
At low flow rates, the Compound Series meter diverts water up
through a bypass to the disc chamber. Leaving the chamber’s
outlet port, water flows beyond the turbine element and main
valve. As the flow rate increases, a pressure differential is created
that opens the main valve. The water then flows straight through
the turbine chamber. In addition, a portion still flows through the
disc chamber before exiting the meter.
The Recordall Compound Series 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 Compound Series meter’s construction complies
with ANSI and AWWA C702 standards. It consists of three basic
components: meter housing, interchangeable measuring elements,
and sealed direct reading registers. The measuring element consists
of the disc measuring chamber, turbine head assembly, and high
flow valve assembly. To simplify maintenance, the registers and
measuring elements can be removed without removing the meter
housing from the line.
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 bronze as an option.
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. And the selflubricating thermoplastic register gearing is designed to minimize
friction and provide long life.
