Badger Meter RTR Specifications
Recordall®
Transmitter Register (RTR)
DESCRIPTION
APPLICATIONS: The Recordall® Transmitter Register (RTR®) is
designed for use with all Recordall Disc, Turbo, Compound and
Fire Service Meters to provide output compatibility with ORION®,
GALAXY, Itron® ERT®, and Badger Meter, Inc. approved AMR
technology solutions.
RESOLUTION: Digital output from the RTR typically has resolution
of 1/10th of the register test circle (resolution may vary in some
cases). The electronic resolution table in this brochure lists
minimum output resolution for all Recordall meter applications.
MOUNTING: The RTR in its shroud assembly uses a bayonet mount
compatible with all Recordall Disc and Turbo meters. A TORX® seal
screw is provided to allow positioning of the register for the most
convenient reading and to secure the register to the meter body in
a tamper resistant mode. The RTR can be removed from the meter
without disrupting water service.
MAGNETIC DRIVE: Direct drive high-strength magnetic coupling
through the meter body to the wetted magnet provides reliable
and dependable register coupling.
SEALED REGISTER: The RTR local register consists of a six-digit
straight-reading mechanical odometer totalizer (located in the
six o’clock position), a 360° test circle with sweep hand, and a
flow finder to detect leaks. The register gearing is self-lubricating
thermoplastic to minimize friction and provide long, reliable
life. Permanent sealing eliminates moisture, dirt, and other
contaminants. The leak rate of the seal is less than 10-6 cc/sec as
tested by a helium mass spectrometer.
TAMPER-PROOF FEATURES: Customer removal of the RTR can be
prevented by using a tamper resistant TORX seal screw. TORX seal
screws are provided as standard accessories with the RTR. Optional
tamper detection seal wire screws are also available.
CONSTRUCTION: The housing of the RTR is constructed of a
strengthened glass lens top and a corrosion-resistant metal
bottom. Internal construction materials are thermoplastics for longlife and high reliability. The integrity of the adhesive seal joining
the glass top to the metal base provide unmatched protection in
water meter applications. A corrosion and tamper resistant TORX
seal screw is provided to secure the RTR to the meter. The shroud
assembly is thermoplastic.
TEMPERATURE: The operating range of the RTR is
–40…49° C (–40…120° F). The water meter should not be
subjected to temperatures below freezing.
MOISTURE: The RTR achieves true water resistance due to the
adhesive technology used in the sealing process. Leak rates less
than 10-6 cc/sec, as tested by a helium mass spectrometer, are
comparable to a true hermetic seal. Due to this unique sealing
process, the RTR exceeds all applicable requirements of AWWA
Standard C707 regarding moisture intrusion. Register fogging and
condensation are no longer an issue.
WIRE CONNECTIONS: The RTR is provided as either a factory
prewired assembly or as a register with pre-sized wire harness
available for connection in the field.
