Embodiment

The liquid level gauge cross-sectional view that the utility model provides sees also Fig. 1, and it comprises the main body pipe 1 that communicates with container, magnetic buoy 11, inditron 2 and the magnetic indicateing arm 22 parallel with the main body pipe.Magnetic buoy 11 is positioned at main body pipe 1, and magnetic indicateing arm 22 is positioned at inditron 2.Magnetic indicateing arm 22 is made up of some indication magnets 223 of series arrangement in inditron.When magnetic buoy in the main body pipe 1 11 with container in during the liquid level change in location, in the inditron 2 parallel with main body pipe 1, corresponding indication magnet 223 south poles are pointed to arrangement angle and will be changed, so can be according to the variation of described arrangement angle, identify magnetic buoy position in the main body pipe, realize the indication of liquid level in the container.As shown in Figure 1, magnetic buoy 11 is a magnetic ball buoy, and the indication magnet 223 in the inditron 2 is indication magnetic ball.Magnetic ball buoy 11 is installed in the main body pipe 1 by two hold-down barss 12 that are parallel to the main body tube wall that pass its south poles respectively.So fixedly the south poles of magnetic ball buoy is pointed to, and avoids its south poles to point to the display result of variable effect indication magnetic ball.

For ease of the arrangement of directly pointing to by indication magnetic ball 223 south poles in the visual inspection inditron 2, avoid utilizing other modes to discern 223 south poles sensing arrangement of indication magnetic ball and raising liquid level gauge cost of manufacture in the inditron 2, inditron 2 selects for use transparent material directly to be made as transparent tube.Just can know the purpose of distinguishing that some indication magnetic ball 223 south poles sensings are arranged for only reaching by naked eyes, can indicate at each and coat the color of distinguishing on the magnetic ball 223.See also Fig. 2 and indication magnetic ball 223 colors shown in Figure 3 are coated with the method synoptic diagram.With Fig. 2 is example, and indication magnetic ball 223 is that its South Pole hemisphere and arctic hemisphere scribble two kinds of different colors respectively.With Fig. 3 is example, and indication magnetic ball 223 is to point to south poles to be divided into two hemisphere, and these two hemisphere scribble two kinds of different colors.223 two hemisphere institutes of indication magnetic ball coating colour is respectively green and white in the present embodiment.Inditron 2 is pointed in the arctic according to magnetic ball buoy 11 among Fig. 1, is convenient to the color of eye-observation to comparatively eye-catching indication magnetic ball, and the arctic hemisphere of indication magnetic ball 223 shown in Figure 2 is painted green, and South Pole hemisphere is white.Green comparatively remarkable to the visual stimulus of human eye, green and white contrasts strong, and human eye is easy to differentiate.

With indication magnetic ball of tinting shown in Figure 2 is example, and when consulting in the main body pipe shown in Figure 4 magnetic ball buoy and arriving in the main body pipe a certain position, the south poles of indication magnetic ball is pointed to the distribution of arrangement angle in the inditron.As shown in Figure 4, the straight line at the south poles of magnetic ball buoy 11 sensing place vertically passes the tube wall of main body pipe 1 and inditron 2 simultaneously, and particularly, arctic N points to indication magnetic balls in the inditron 2.The dotted line that has arrow is the lines of magnetic induction distribution schematic diagram of magnetic ball buoy 11.Magnetic induction the closer to magnet south poles two is strong more, and this is known physics conclusion.The physics conclusion can be derived thus, and the influences that indication magnetic ball south poles in the inditron 2 are pointed to of the lines of magnetic induction that distributes of the magnetic ball buoy 11 that points to of south poles are very remarkable as shown in Figure 4, especially to the south poles of the indication magnetic ball parallel with magnetic ball buoy 11.If the observer observes the shown color that goes out of indication magnetic ball in the inditron from Fig. 4 left side, the green arctic of the indication magnetic ball parallel with magnetic ball buoy 11 simultaneously is fully towards the observer's.With this green arctic is separation towards the indication magnetic ball on a left side fully, is positioned at the green arctic of the above indication magnetic ball of this indication magnetic ball gradually up until pointing to the inditron top fully; Be positioned at the green arctic of the following indication magnetic ball of this indication magnetic ball gradually down until pointing to the inditron bottom fully.Therefore point to by indication magnetic ball south poles in the Direct observation inditron and arrange the position of judging magnetic ball buoy in the main body pipe.
