Metering Enclosure With Specially Hinged Front Cover

A hinged enclosure using two ball-headed screws (16a, 16b) at the corners of a rectangular cover (12) and two other fasteners (16c, 16d). The other two fasteners (16c, 16d) and the ball-headed screws (16a, 16b) are loosened to allow the cover (12) to be moved first outwardly away form the enclosure body (11) and the other two fasteners are then removed to allow the cover (12) to be pivoted around the two loosened ball-headed screws (16a, 16b). There are stand-offs (20a-20d) at the corners of the enclosure body (11) to restrict movement of the cover (11) until the cover (11) is moved away from the body (11), and before pivoting the cover (12) on the ball-headed screws (16a, 16b). There is a seal (21) around the rim of the cover (12), such that the cover (12) must be lifted first, before the cover (12) is pivoted. The cover (12) contains an electronic display and a display circuit board module (19) is attached on the underside of the cover and these must be protected when the cover (12) is opened during service or installation.
