Abstract: Described herein are embodiments of methods, devices and computer program products for tamper detection in a meter. One aspect of the method includes using a magnetic field strength sensor to continuously detect magnetic field strength proximate to a meter. In one aspect, the magnetic field strength sensor produces an analog voltage signal proportional to the detected magnetic field strength. The analog voltage signal of the sensor is continuously converted to a digital voltage signal. The digital voltage signal is stored in a memory at timed intervals, and the digital voltage signal is monitored for an aberration that indicates tampering of the meter. If tampering is detected, then an alarm is triggered to indicate the tampering.

In one aspect, the magnetic field strength sensor produces an analog voltage signal proportional to the detected magnetic field strength. The analog voltage signal of the sensor is continuously converted to a digital voltage signal. The digital voltage signal is stored in a memory on an intermittent basis, and the digital voltage signal is monitored for an aberration that indicates tampering of the meter. If tampering is detected, then an alarm is triggered to indicate the tampering.
