成される。However, according to the present invention, the purpose of the lever is to sense changes in the liquid level in the tank using the float, and measure the amount of movement of the float via the tape.
In the liquid level gauge that transmits information to the liquid level display, the tape reel for winding the tape that hangs the float is composed of a double reel consisting of an outer reel and an inner reel that is rotatable relative to the outer reel.
This is achieved by drawing out the tape wound around the inner reel through a through hole provided in the outer reel, attaching a float to the tip of the tape, and then fixing the inner and outer reels to each other.

に浮子２を取付ける。The end of the tape 3 is wound around the inner reel 5b, pulled out through the through hole 15 provided in the outer reel 5α, and the float 2 is attached to the tip of the tape 3.
次に使用法及び動作について説明する。Next, usage and operation will be explained.
油貯蔵タンク１に本発明の液面計をセントするに際し、
液面表示部１６の目盛テープ１０を零位置にし、リール
５の外側リール５αと内側リール５ｂは相互にフリーに
しておく。When placing the liquid level gauge of the present invention in the oil storage tank 1,
The scale tape 10 of the liquid level display section 16 is set to the zero position, and the outer reel 5α and the inner reel 5b of the reel 5 are kept free from each other.
内側リール５ｂに巻かれているテープ３を外側リール５
αの貫通孔１５から引出せば、内側リール５ｂのみが回
動しテープ３は繰り出されていく。The tape 3 wound on the inner reel 5b is transferred to the outer reel 5.
When the tape 3 is pulled out from the through hole 15 at α, only the inner reel 5b rotates and the tape 3 is fed out.
このテープ３の先端には浮子２を取付け、該浮子３がタ
ンク１の底板に接したところでテープ３の引出しを止め
、ネジ１４を用いて外側リール５αと内側リール５ｂと
を相互に固定する。A float 2 is attached to the tip of the tape 3, and when the float 3 comes into contact with the bottom plate of the tank 1, the tape 3 is stopped from being drawn out, and the outer reel 5α and the inner reel 5b are fixed to each other using screws 14.
このようにすれば・、テープ３は貫通孔１５の端から外
側リール５αに巻き始められることになシ、チー′プ３
にはリール５αを介して定トルクスプリング７により常
に一定の巻回方向への張力が加えられる。In this way, the tape 3 will start winding on the outer reel 5α from the end of the through hole 15,
A constant tension in the winding direction is always applied by a constant torque spring 7 to the reel 5α.
一方、目盛テープ１０はこの状態では液量零の位置にあ

これで液面計のセントが完了し、タンク１内に油を入れ
ると、浮子２は油面の上昇に従って上昇し、その分だけ
テープ３は外側リール５αに巻取られ、同時にリール９
及びリール１１は第１図で時計方向に（９）転し、目盛
４−プ１０も移動して油量表示数は増加する。This completes the centing of the liquid level gauge, and when oil is put into the tank 1, the float 2 rises as the oil level rises, and the tape 3 is wound on the outer reel 5α by that amount, and at the same time, the reel 9
Then, the reel 11 rotates clockwise (9) in FIG. 1, the scale 4-10 also moves, and the number of oil amount displayed increases.
また、タンク１内の油を排出した場合は、油面が下がる
とともに浮子２も下がシ、外側リール５αからテープ３

テープ１０の油量表示数は減少する。In addition, when the oil in the tank 1 is drained, the oil level goes down and the float 2 also goes down, and from the outer reel 5α to the tape 3
is fed out, the reels 5, 9, and 11 are reversed, and the number of oil amounts displayed on the scale tape 10 decreases.
