OUTAGE INDICATING APPARATUS FOR METER TELEMETRY SYSTEMS INCLUDING DATA RECORDERS

摘要

OUTAGE INDICATING APPARATUS FOR METER TELEMETRY SYSTEMS INCLUDING DATA RECORDERS An outage in a quantity measured by a meter develops a signal in a data recorder included in a telemetry system to record data signals initiated by the meter. The data signals and time interval signals are recorded as pulses in separate data and time tracks in a recording medium. An outage pulse is recorded in the time track in an immediately adjacent relationship prior to the recording of an interval pulse. m e outage pulse is positioned for detection in a translator upon a reverse direction of translation of the data and interval recorded pulses so as to indicate the time of the outage condition.
