VRT Direct Gas-meter Transponder
Overview
The TRACE VRT™ Direct Gas-meter Transponder (DGT) is
designed for use with most residential diaphragm meters. VRT
Direct Gas-meter Transponders for residential meters are available
in three distinct types:
• Type A = American Meter Company
®
products
• Type R = Rockwell / Equimeter / Invensys
®
• Type S = Sprague / Schlumberger / Actaris / Metris
®
The VRT DGT can be programmed for use with a fixed factor,
pressure-compensated index.
The VRT 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 up to four time-of-use (TOU) electronic indexes that
each have programmable start and stop times.
