Abstract

A device for detecting tampering of a utility meter includes sensors to detect a positional displacement of the meter and loss of power to the meter. On sensing a positional displacement of the meter, indicative of an attempt to remove the meter, a timer is activated to enable sensing a power loss to the meter. In response to detection of a power loss during the time period defined by the timer, an indication is stored in a nonvolatile memory of the tamper event. In response to loss of power with or without a detection of tampering, required parameters including utility consumption data are stored in nonvolatile memory. Remote access to and data retrieval from the nonvolatile memory and system are provided over telephone lines, power lines, or a radio frequency circuit.
