ABSTRACT:
A water meter is locked into its housing to prevent tampering by placing a cover over a hexagon nut and a hand nut. Relative rotation between the hexagon nut and the hand nut is necessary to remove the meter from the housing. The cover has a wrench which fits the hexagon nut and prevents relative rotation between the hexagon nut and the cover. The cover has a boss which engages the hand nut and prevents relative rotation between the case and the hand nut. The cover has legs which engage the housing to prevent relative rotation between the cover and the housing.
