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
®
, Badger
®
ERT
®
, Badger
Touch, and Badger Meter, Inc. approved AMR technology solutions.
RESOLUTION: Digital output from the ADE includes the option of either
4, 5 or 6 dial resolution.
MOUNTING: The ADE in its shroud assembly uses a bayonet mount
compatible with all Recordall disc, turbo, compound and fire series
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 ADE 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 ADE local register consists of a six-digit
straight-reading mechanical odometer totalizer (located in the 12
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 ADE can be
prevented by using a tamper resistant Torx seal screw. Torx seal
screws are provided as standard accessories with the ADE. Optional
tamper detection seal wire screws are also available.
CONSTRUCTION: The housing of the ADE is constructed of a
strengthened glass lens top and a copper alloy metal bottom. Internal
construction materials are thermoplastic for long-life 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 ADE
to the meter. The shroud assembly is thermoplastic.
TEMPERATURE: The operating range of the ADE is -20° C to 49° C
(-5°F to 120°F). The water meter should not be subjected to
temperatures below freezing.
MOISTURE: The ADE 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 ADE
exceeds all applicable requirements of AWWA Standard C707 regarding
moisture intrusion. Register fogging and condensation are no longer
an issue.
WIRE CONNECTIONS: The ADE is provided as either a factory
prewired assembly or as a register with pre-sized wire harness
available for connection in the field. Operation of the ADE is dependent
of the wire length limitations of connected MRT equipment.
ELECTRICAL: The electronic circuitry is designed to provide immunity
to electrical surges and transients per IEC801-2, IEC801-4 Severity
Level 4.

OPERATING CHARACTERISTICS: The ADE reading is obtained
directly from the position of the register's odometer wheel stack
utilizing a non-contact frictionless form of absolute encoding. The
encoder provides accurate readings by using internal light sources to
determine the exact position of the number wheel. This technology
eliminates electrical contacts and wipers that could wear out and
provides greater long-term performance. No batteries are required to
maintain the reading.
