Meter interface. Using a mechanical-to-digital interface, the VRT
gas transponder senses the output of a utility meter, translates this
into electronic form and stores it in the transponder’s memory.
Tamper sense and flagging. When the VRT gas transponder is
installed and programmed, a baseline orientation for its internal
tamper sense is set. Any deviation from that baseline setting will
trigger a tamper indication.
Transponder data acquisition. The VRT gas transponder is
programmed with a unique serial number at the time of
manufacture. Upon installation on a meter, the current (or baseline)
meter index reading is also programmed into the transponder’s
memory. As the meter measures consumption and the index is
advanced, the index reading stored in the transponder’s memory is
automatically updated. The transponder also records changes to the
tamper detection sensor.
Pressure-compensation factor. For VRT gas transponders using
firmware version category 9 or higher, a pressure-compensation
factor can also be programmed into the transponder memory
ensuring the transponder readings match the pressure-
compensated mechanical index reading.
Route information loading. Route data includes transponder serial
number, meter account address, and latitude/longitude coordinates
(when available), among other items. This information is
downloaded to the interrogator prior to commencing automated
meter reading. By also tracking the vehicle or interrogator’s
coordinates, a GPS-equipped system determines which
transponders in the route should lay within range at any given time
and transmits those serial numbers requesting meter data.
Interrogation. Once placed in an interrogation mode by the meter
reader, the TRACE interrogator transmits serial number(s) of the
desired transponder(s) along with a command (or commands)
requesting the contents of each transponder’s memory.
Transponders are selected for reading on the basis of route and
meter location information stored in the interrogator and presence of
the transponder within range of the interrogator.
Route data processing. Meter data from a transponder is stored in
the interrogator’s memory for transfer to the utility’s host computer
for processing. AMCO Automated Systems Route Manager
software makes it easy for the utility to process route data and
configure routes for AMR.
