    DETAILED DESCRIPTION

    [0036] As illustrated in FIG. 1 and FIG. 2, instrument enclosure [100] includes left and right mounting plate sections [101,102] which when joined create the mounting plate [203, shown completed in FIG. 2] affixed to a standpipe [104] or other suitable standing structure onto which the instrument enclosure [100] mounts. The mounting plate sections [101,102] may be made of metal or other suitable material(s). The mounting plate sections [101, 102] are joined by aligned apertures [105-1] using suitable fastening means [105-2], such as nuts and bolts. The left and right mounting plate sections [101, 102] are identical, both having a planar top surface [106], arched recess [107] to receive a cylindrical standpipe [104], and fixed triangular supports [108]. A clamp [109] supports the mounting plate [203] and prevents vertical movement of the instrument enclosure [100].

    [0037] A field instrument [110] can be directly mounted, affixed, or otherwise attached to the standpipe [104] or other suitable standing structure that limits contact of the instrument with the instrument enclosure [100]. The mounting plate [203] provides support to the instrument enclosure [100] separately and apart from the support of the field instrument [110].

    [0038] In addition, the illustrated field instrument [110] is attached to process line tubing [111,112] configured to provide a process flow, as well as measurable parameters, to the field instrument [110]. The illustrated instrument enclosure assembly [100] includes a rigid or semi-rigid instrument enclosure [100] configured to be attached to standpipe [104] or mounting plate [203] such that the instrument enclosure [100] encompasses field instrument [110] while permitting ingress/egress for the process line tubing [111,112].

    [0039] In one embodiment, field instruments [110] having similar operating requirements can be used in tandem allowing more than one field instrument [110] to be included within the instrument enclosure [100].

    [0040] In a further embodiment, the arched recess [107] can be provided in any suitable shape that can accommodate a suitable standing structure other than a standpipe [104] having a cylindrical shape. These recesses [107] may be shaped in accordance with the shape of the standpipe [104]. For the circular embodiment of the standpipe [104] presented, each recess [107] may define a semicircular arc.

    [0041] The field instrument [110] can be attached to the standpipe [104] using a single attachment as shown in FIG. 4, FIG. 5, and FIG. 6, or a double attachment as shown in FIG. 1, FIG. 2, and FIG. 3.

    [0042] FIG. 3 illustrates the inner assembly of the lower portion of an instrument enclosure [100]. The left and right bottom base sections [312,313] are mirror images and therefore are arranged in a reverse configuration when compared to the other. The left bottom base section [312] is distinct and detachable from the right bottom base section [313]. The bottom base sections [312,313] are connected together along respective L-shaped edges [314-1, 314-2] forming the bottom base [415] (shown completed in FIG. 4). Hinges [403] (shown in FIG. 4) or other suitable attachments can be provided. Hinges [403] may enable top casing [601, shown in FIG. 6] to rotate between an open position as best shown in FIG. 6 and a closed position (shown in FIG. 7).

    [0043] The bottom base sections [312,313] may be connected by one or more fasteners 105-2, which may be implemented as hinged fasteners or as any other suitable type of rigid fastener. The bottom base sections [312,313] are joined atop the mounting plate [203] where a portion of the left and right mounting plate sections [101,102] are left accessible under the bottom base [415], as shown in FIG. 4, for the mounting of the left and right bottom casing segments [401,402].

    [0044] FIG. 5 illustrates the attachment of the right bottom casing segment [402] to the right bottom base section [313].

    [0045] Each bottom base section [312,313] includes a lower planar portion [320] and an upper planar portion [321] that is perpendicular or substantially perpendicular to the lower planar portion [320].

    [0046] As illustrated in the figures, the lower planar portions [320] of the bottom base sections [312, 313] are oriented in a substantially horizontal plane while the perpendicular upper planar portions [321] of the bottom base sections [312,313] are oriented in a substantially vertical plane. Each lower planar portion [320] may include or define a recess [107] configured to engage standpipe [104] such that the two bottom base sections [312,313] may be attached to one another while engaging the standpipe [104].

    [0047] Each upper planar portion [321] may include or define a lipped recess [322] having a lip [323] configured to engage the top [316] and bottom portal plates [317] having dual concavity sections [318] that when joined form ingresses [416,417] (shown in FIG. 4) that can be used for additional portals for data collection and monitoring. A gasket [319] or other suitable sealing means is fitted within the lip [323] of the lipped recess [322] of the upper planar portion [321] to provide additional environmental isolation between the environment and enclosed space(s) defined when the instrument enclosure [100] is in a closed configuration. The outward edges of the ingresses [416,417] of FIG. 4 are sealed with a transparent or translucent glass or plastic lens [418], that can be planar, convex, concave or otherwise shaped for optimization of the field instrument(s) [110] enclosed within the instrument enclosure [100].

    [0048] In further embodiments, the lenses [418] can be made of any suitable material or combination of materials that allows for optimal function and data collection of the field instrument(s) [110] within the instrument enclosure [100].

    [0049] The top casing [601] and complete bottom casing [602, which is consists of 312, 313, 401, 402] illustrated in FIG. 6, are substantially triangular in cross section as best illustrated by the substantially triangular side panel [611] of top casing [601] and the substantially triangular side panels [612] of bottom casing [602]. A front panel [613] of top casing [601] is illustrated with an optional window [645] to enable visual inspection of the instrument enclosure [100] without opening the instrument enclosure [100]. A window [645] may be comprised of tempered glass or any other sufficiently transparent and durable material.

    [0050] As best illustrated in FIG. 6, the instrument enclosure [100] is in an open position, with a top section casing [601] that includes first, second, third, and fourth edges [641-1, 642-1, 643-1, and 644-1]. Similarly, a bottom section casing [602] includes first, second, third, and fourth edges [641-2, 642-2, 643-2, and 644-2]. The first edge [641-2] of the bottom casing [602] may be hinged or otherwise rotatably-affixed to the first edge [641-1] of the top casing [601] via one or more hinges [403] or other suitable attachment means, in which second, third, and fourth edges [642-1, 643-1, and 644-1], of top casing [601] are in contact with or in close proximity to second, third, and fourth edges [642-2, 643-2 and 644-2] of the bottom casing [602].

    [0051] Although the figures illustrate hinging between the top casing [601] sections and the bottom casing [602] sections along first edges [641] of the top casing [601] sections and the bottom casing [602] sections , embodiments of the instrument enclosure [100] may include additional hinging between top casing [601] and bottom casing [602] sections to provide variations of open and closed configurations of instrument enclosures [100] in addition to the open and closed configurations supported by the illustrated hinging. Such additional hinging may include, without limitation, fixed or detachable hinging between second edges [642], fixed or detach hinging between third edges [643], and fixed or detachable hinging between fourth edges [644].

    [0052] In the closed position, the top casing [601] and bottom casing [602] cooperatively define an instrument enclosure space within which a field instrument [110] may be located as described in more detail below. In at least some embodiments, top casing [601] and bottom casing [602] sections cooperatively form a cubic or substantially cubic instrument enclosure [100]. In at least some other embodiments, the top casing [601] and bottom casing [602] sections cooperatively form a rectangular cuboid or substantially rectangular cuboid instrument enclosure [100].

    [0053] The left and right bottom base sections [312,313] illustrated in FIG. 3-FIG. 6 further include or define notches [315], configured to engage tubing [433] and provide for enclosing power wires [436], and notches [315], configured to engage tubing [434] that also encloses communication wires or fibers [437]. The upper planar portions [321] define corresponding notches [315] configured to engage process line tubing [111,112] such that the lower and upper planar portions [320,321] may be connected to each other while engaging process line tubing [111,112], allowing for process line tubing [111,112] to enter the instrument enclosure [100]. While the notches [315] are illustrated in FIG. 3 as smooth and continuous arcs, embodiments may incorporate grooves and/or other elements to better restrict or engage the applicable pipes, tubing, or other structural elements.

    [0054] Gaskets or other type of sealing structures (not depicted) may be employed to provide additional environmental isolation between the environment and enclosed space defined when the instrument enclosure is closed.

    [0055] The illustrated instrument enclosure [100] is configured for independent attachment to the support and includes three mutually adjustable parts—top casing [601] section, left bottom casing segment [401], and right bottom casing segment [402], that provide structure for removing and replacing the instrument enclosure [100] for a field instrument [110] attached to the process line tubing [111,112] without detaching the field instrument [110] from the standpipe [104] or other support structure or from the process line tubing [111,112].

    [0056] In a similar embodiment, the mounting plate assembly [203, not shown] may include a field instrument column [667] as shown in FIG. 6 that extends from a mounting plate [203, not shown] and further fitted with the left and right bottom casing segments [312,313]. In such assemblies, even though field instrument column [667] occupies volume analogous to the volume occupied by standpipe [104] shown in FIG. 1 through FIG. 5, the mounting plate embodiment illustrated in FIG. 6 enables a beneficial pre-field attachment of the field instrument [110] to the field instrument column [667], i.e., attachment of the instrument to the enclosure before the field instrument [110] is brought to the field, thereby greatly easing the burden experienced during installation. In other mounting plate embodiments, the field instrument may be attached directly to the mounting plate [203] thereby achieving the pre-field attachment feature described above for the embodiment depicted in FIG. 7, but also potentially enabling an instrument enclosure with a smaller footprint, an instrument enclosure with more interior space, or both.

    [0057] Supporting the field instrument may include one or more operations including: attaching the field instrument to the standing structure, wherein the instrument enclosure defines an aperture configured to receive a terminal portion the standing structure and attaching the field instrument to one or more attachment features of the instrument enclosure.
