According to an exemplary embodiment of the present invention, there is provided a fuel tank liquid level sensing apparatus, which is adapted to be mounted to a fuel tank, for example, provided with a mounting flange (not shown), wherein the fuel tank is formed with (e.g., on the mounting flange thereof) a plurality of mounting holes 6 for mounting the level sensing device, and for different types of fuel tanks, the possibility of having a layout of the plurality of mounting holes 6 thereon with multiple orientations, in other words, the layout of the plurality of mounting holes 6 with multiple orientations that are selectable (four different orientations of the five mounting holes 6 are shown in figures 7A-7D by way of example for a tank with a five-hole mounting flange, and the orientation of the five mounting holes 6 on a certain tank may be any one of these four orientations), that is, the orientation of the plurality of mounting holes on different fuel tanks may be one of the plurality of orientations; the oil tank liquid level sensing device comprises a first flange plate 1, a second flange plate 2 and a sensing assembly 3 connected to the second flange plate 2; wherein the first flange plate 1 can rotate to different orientations during installation so that the plurality of connecting holes 11 are respectively aligned with the plurality of mounting holes 6; an arc-shaped groove 21 corresponding to the connection hole 11 in the radial direction and extending in the circumferential direction is formed in the second flange 2, the arc-shaped groove 21 being provided: for each of the plurality of orientations of the plurality of mounting holes 6, a fastener is permitted to pass through the attachment hole 11, the arcuate slot, and into the mounting hole 6 to secure the first and second flanges 1, 2 (and the sensing assembly carried thereon) to the fuel tank.

Furthermore, as the first flange plate 1 is only provided with the plurality of connecting holes 11 which cover the second flange plate 2 with the arc-shaped groove, the dustproof and waterproof effects on the interface of the oil tank for installing the sensing device are achieved.
In fig. 2A-2D and 3, by way of example, five connection holes 11 are shown in the first flange 1, and correspondingly five mounting holes are shown in the mounting flange of the fuel tank, said arc-shaped slots being arranged: for each of the orientations of N × 90 ° of the connecting hole 11 and the mounting hole, the five fasteners are allowed to sequentially pass through the corresponding connecting hole 11 and the arc-shaped groove and enter the mounting hole, wherein N is any one of 0, 1, 2 and 3.
For a five hole fuel tank mounting flange, it has four mounting orientations according to industry standards, namely N x 90 ° orientation, where N is any one of 0, 1, 2, 3.

The arrangement of the arcuate slots in the second flange 2 is shown in figures 4 and 7A-7D. As can be seen from fig. 7A-7D, when the mounting holes 6 (although the first flange plate is not shown in fig. 7A-7D in order to better illustrate the relationship of the arcuate slots and the mounting holes, the connection holes 11 of the first flange plate are aligned with the mounting holes 6) are at 0 ° (fig. 7A), 90 ° (fig. 7B), 180 ° (fig. 7C), 270 ° (fig. 7D), the through arcuate slots are aligned with the connection holes 11 and the mounting holes 6 to allow fasteners to pass through the connection holes and the arcuate slots into the mounting holes 6. Therefore, the arrangement of the arc-shaped groove of the second flange 2 enables the oil tank liquid level sensing device to be adapted to oil tanks of four different types, namely to the oil tanks of the mounting holes in four different directions.
As an example, as shown in fig. 4, the arc-shaped slots 21 include a plurality of first arc-shaped slots 211 and a plurality of second arc-shaped slots 212 which are concentrically arranged, wherein a central angle of the first arc-shaped slots 211 (i.e., an included angle between a line connecting both ends of the arc-shaped slots and a center of the arc-shaped slots) is larger than a central angle of the second arc-shaped slots 212, and the first arc-shaped slots 211 and the second arc-shaped slots 212 are alternately arranged, and adjacent first arc-shaped slots 211 and adjacent second arc-shaped slots 212 are spaced apart by a solid portion 24.

The cable 33 may be used to transmit signals of the sensing assembly. The arrangement of the housing 23 on the second flange 2 provides water protection to the interior of the tank. As can be seen in fig. 2A-2D, the housing 23 is disposed atop the second flange 2 and extends from the central aperture 12 of the first flange 1.
In order to accommodate different tank depths, the sensing device further comprises a support arm as described above, which support arm is fixedly connected at one end to the second flange 2 at a side remote from the first flange 1 and at the other end to said sensing member 3, wherein the height of the support arm 4 is adjustable. Because the height of the supporting arm is adjustable, the liquid level sensing device can be suitable for oil tanks with different depths.
Illustratively, as shown in fig. 5 and 6, the supporting arm 4 includes a first arm 41 fixedly connected to the second flange 2 and a second arm 42 connected to the first arm 41, and the sensing assembly 3 is disposed at an end of the second arm 42 away from the first arm 41, wherein one of the first arm 41 and the second arm 42 has an elongated slot 401 formed therein and the other has a fixing hole 402 formed therein, so that a fastener passes through the elongated slot 401 and the fixing hole 402 to fix the second arm 42 to the first arm 41. In fig. 5 and 6, it is schematically shown that the upper end of the second arm 42 is provided with 4 fixing holes 402 so that four fasteners can pass through the four fixing holes 402 and the elongated slot 401 to fix the second arm 42 to the first arm 41.
The sensor assembly 3, which is an example tank level sensor arrangement, may comprise a float 32, a sensor housing 5 arranged at the lower end of the support arm 4, and a substantially horizontally extending float arm 31, one end of the float arm 31 being connected to the float 32 and the other end being arranged in said sensor housing 5 for triggering said sensor element. As an example, sensing elements such as reeds and resistive patches may be provided in the sensor housing 5, although other types of sensing elements may be used. The float arm may be designed to have the greatest length of the float arm lengths required for all tanks to which the sensing device is likely to be applied, and during installation, the float arm is custom tailored to the particular size of the tank.
In the above exemplary embodiments, the liquid level sensing device can be applied to the oil tank mounting flange with mounting holes in different orientations by the design of the mounting mechanism of the first flange and the second flange with the arc-shaped groove; through the design of the supporting arm with adjustable length, the liquid level sensing device can be suitable for oil tanks with different depths; the float arm is designed to be the maximum length required by a common oil tank and cut on site, so that the liquid level sensing device can be suitable for oil tanks with different lengths.
