Absolute Digital Encoder
DESCRIPTION
Applications: The Absolute Digital Encoder (ADE®) is designed
for use with all Recordall® Disc, Turbo, Compound and Fire Service
meters to provide connectivity with ORION®, GALAXY,
BadgerTouch® Itron ERT, and Badger Meter approved AMR/AMI
technology solutions.
Electronic Resolution: Digital output from the ADE includes the
option of either four, five or six dial resolution. Refer to tables on
the next page for details.
Mounting: The ADE in its shroud assembly uses a bayonet mount
compatible with all Recordall Disc, Turbo, Compound and Fire
Series meters. The bayonet mount allows positioning of the register
in any of four orientations for visual reading convenience. The ADE
can be removed from the meter without disrupting water service.
Magnetic Drive: A direct-drive, high-strength magnetic coupling
through the meter body to the wetted magnet provides reliable
and dependable register coupling.
Local Indication: The ADE register face features a six-digit
mechanical odometer wheel stack, a 360° test circle with sweep
hand, and a flow finder to indicate leaks.
Tamper-Resistant Features: Unauthorized removal of the register
or encoder is inhibited by the option of a tamper detection seal
wire screw, resistant 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.
Construction: The housing of the ADE is constructed of a
strengthened glass lens top and a corrosion-resistant metal
bottom. Internal construction materials are thermoplastic for long
life and high reliability. The register gearing is self-lubricating
thermoplastic to minimize friction and provide long, reliable life.
The shroud assembly is thermoplastic.
Temperature: The operating range of the ADE is – 40…140° F
(– 40…60° C ). The water meter should not be subjected to
temperatures below freezing.
Sealing: The ADE achieves true water resistance due to the
adhesive technology used to seal the glass dome to the corrosion
resistant metal bottom. 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 ADE exceeds all
applicable requirements of AWWA Standard C707 regarding
moisture intrusion.
Wire Connections: The ADE is available with either a wire lead,
fully potted to prevent moisture intrusion at the connections, or
with terminal screws. When provided with a wire lead, the ADE
may be pre-wired at the factory to select Badger Meter-approved
AMR/AMI endpoints, or may be furnished with a variety of lead
wire lengths. Lead wire equipped ADE registers are suitable for
installation in all environments, including continuously submerged
water meter pits.

The terminal screw version ADE features a tamper-resistant cap
over the three-wire terminals. ADE registers with terminal screws
are for indoor installation in protected environments, such as
residential basements.
Electrical: The electronic circuitry is designed to provide immunity
to electrical surges and transients per IEC801-2, IEC801-4 Severity
Level 4. Operation of the ADE is dependent on the wire length
limitations of connected AMR equipment.
Operating Characteristics: The digital reading obtained by an
AMR/AMI device is sensed directly from the position of the ADE
register’s odometer using internal LED light paths to determine the
exact position of each number wheel. This technology eliminates
electromechanical contacts that could wear out, and provides
greater long-term performance.
