APPLICATIONS: The 50W ERT ®
is an automated meter reading module designed
for compatibility with the Hersey ®
Translator ™ Register. Utilizing open
architecture and dual-mode operational capability,
the ERT device provides flexibility, ease
of use and exceptional battery life. The
ERT device can be mounted indoors or outdoors,
above grade. It encodes data from the register;
receives data in the form of a wake-up call
from a reading device (when in the appropriate
mode); and then transmits the meter data
to the reading device. Benefits of the ERT
include accurate data collection, improved
meter reading efficiency, and improved customer
relations through better resource management.
Existing Hersey Meters can be retrofit with
ERTs. Call Hersey Customer Service to find
out about your meters' requirements.
OPERATION: The ERT meter module
can be programmed to communicate in either
wake-up or bubble-up mode. When used in
wake-up mode, it waits for a wake-up signal
over a radio frequency and then automatically
transmits the meter data to the appropriate
meter-reading device. In bubble-up mode,
a constant stream of data is transmitted
for interception, by the receiving unit,
and no FCC license is required. This data
includes the meter ID number, registration,
and tamper detection information. The RF
transmission lasts less than one second
and contains eight identical data packets,
each at a different frequency. The modules
can be read by DataCommand, DataPac and
Mobile Collection Systems as well as the
G5R handheld and the fixed base MicroNetwork.
See a Hersey Salesman for the system that
best suits your needs. Power is provided
by two long-life, replaceable "A"
cell lithium batteries. Estimated battery
life when used in bubble-up mode is 10 years.
Estimated battery life when used in wake-up
in wake-up mode is 20 years, which is the
same as the life expectancy of the ERT module,
meaning no battery change out would be necessary.
CONFORMANCE TO STANDARDS: Complies
with FCC regulations: Part 15 certified.
No FCC license is required if the ERTs are
used in bubble-up mode and the reading device
used does not transmit a wake-up signal.
CONSTRUCTION: Weather-proof polycarbonate
housing with encapsulated electronics components.
