EnergyAxis Direct Gas-meter Transponder
Overview
The EnergyAxis Direct Gas-meter Transponder (DGT) is designed
for use with most residential diaphragm meters. EnergyAxis Direct
Gas-meter Transponders for residential meters are available in
three distinct types:
• Type A = American Meter Company
®
products
• Type R & R415 = Rockwell / Equimeter / Invensys
®
• Type S = Sprague / Schlumberger / Actaris / Metris
®
The EnergyAxis DGT can be programmed for use with a fixed
factor, pressure-compensated index.
The EnergyAxis DGT maintains the current time and date, which are
used to manage the recording of real-time data for retrieval as
required during the normal read cycle.
In addition to maintaining index reading, the transponder:
• Stores 35 daily index readings in separate electronic indexes
recorded at the start of the utility day. (The utility day start time
is programmable).
• Maintains interval data for each 15 minute, 30 minute or 60
minute interval (default). Up to 35 days of 60 minute interval
data will be stored by our module.
