APPLICATIONS: The Hersey® Translator Encoder Register is
available on all current model Hersey meters for use in Automatic
Meter Reading Systems (AMR). The register allows accurate readings
to be obtained conveniently from residential, commercial and
industrial meter installations in hard-to-access locations. Using
the Translator Encoder Register with an AMR system can increase
the efficiency and accuracy of the meter reading process.
The register is a true absolute encoder register that provides
direct electronic transfer of meter reading information from a
current Hersey meter to any of a number of AMR device options.
The register sends data in ASCII format (American Standard code
for Information Interchange), a standard format used by virtually
all modern computers and communications devices. The Translator
Encoder Register uses the same open architecture variable
length protocol in ASCII format as is used by other commonly
used encoder registers.
The register is available for meter sets installed indoors with a run
of wire up to 300 feet to an outside wall mounted touch pad. For
pit applications, the Translator Encoder Register is factory wired
and potted to provide reliability in moist conditions.
With minimal cost and labor, the Translator Encoder Register can
be retrofitted to current Hersey meters already in service.
CONFORMANCE TO STANDARDS: Complies with AWWA Standard
C707 for Encoder Remote Reading Systems, American Standard
Code for Information Interchange (ASCII).
CONSTRUCTION: The Translator Encoder Register is permanently
sealed to exclude dirt and/or moisture infiltration. The register
has a straight reading odometer-type display, and 360º test circle
with center sweep hand and low flow (leak) detector. A tamperproof
locking feature is provided to resist tampering with the
register. For pit applications, the wire assembly is factory potted
for moisture resistance.
OPERATION: The Hersey Translator Encoder Register uses an
absolute encoder to directly read the actual position of the index
odometer wheels, when interrogated by a reading device (Touch
Probe, Radio MIU or Telephone MIU). The reading device provides
all necessary power. There are no pulse outputs or memory
modules to program and the register has no battery.
When an AMR device interrogates the register, the translator encoder
communicates to the device in ASCII computer language the
absolute meter reading, and an eight-digit identification number.
Any error or nonread is immediately indicated by the meter reading
equipment, providing virtually error-free reading.
All Translator Encoder Registers are standard with full 6-wheel
encoding, and have a 6-wheel odometer assembly for direct manual
reading. The electronically collected data will depend upon the
particular requirements of the utility. Utilities billing in common
units, such as thousands of gallons or hundreds of cubic feet,
are able to use the electronic meter readings without performing
intermediate calculations. This can be done by specifying 4, 5, or
6-wheel encoding Translator Encoder Registers.
