Abstract
A watthour meter has, in one aspect, a flexible seal with a locking head carried on the meter base and a strap extending from the head and disposable in a loop around and through apertures in juxtaposed mounting flanges of the meter base and the meter dome to lockably join the dome and base. A tamper detector is carried on a blade moveably extending through the base. Movement of the blade during separation of the meter from the meter socket jaw contacts triggers the tamper detector. A connecting pin extends through aligned openings in the base and the dome to non-separably join the base and the dome. The pin engages a tamper signaling switch to provide an indication of a change of in pin state during a tamper event.
