摘要

OUTAGE INDICATING APPARATUS FOR METER TELEMETRY SYSTEMS INCLUDING DATA RECORDERS An outage condition in a quantity measured by a meter is detected in a data recorder that is connected in a telemetry system to record the meter data information. Data pulses and time interval pulses are recorded in separate data and time tracks of a recording medium. An outage indicating pulse is recorded in the time track preferably in a predetermined relationship to an interval pulse. The outage pulse is detected in a translator upon translation of the recorded data and interval pulses so as to indicate the time of the outage condition,
