Abstract

The utility model relates to a liquid level meter for monitoring the liquid level of a large-sized storage tank, which is composed of a float, a float guiding device, a traction steel wire, guide wheels, a heavy hammer and an encoder, wherein, the encoder comprises a code wheel, a shaft and a codedisc which is provided with a slit; the code wheel and the codedisc are arranged on the shaft; the code wheel is wound with the traction steel wire which is among the guide wheels and rotates along with the displacement of the traction steel wire. The liquid level meter has the advantages of high measuring precision, easy installation and reliable operation.

Description

Liquid level meter

The utility model relates to a kind of liquid level gauge, mainly is used for the liquid level of large-scale storage tank is monitored for departments such as oil, chemical industry and communications and transportation.

Existing liquid level gauge can be with reference to figure 1, place the float 7 on storage tank 13 liquid levels, be under the guiding of floater guiding device 8 of guide pole at steel wire 9 with tensioning, float 7 is followed the lifting of liquid level and is done fluctuating of level along guiding steel wire 9, lie in traction steel wire 10 on the float under the guide effect of a plurality of guide wheels 11, make the weight that lies in steel wire 10 other ends do vertical decline and rising with the float lifting, the displacement of weight promptly characterizes out the changing value of liquid level in the storage tank.Its weak point is: measuring accuracy is low.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of liquid level gauge is provided.

The purpose of this utility model can reach by following measure:

The utility model is made up of float, floater guiding device, traction steel wire, guide wheel, weight and scrambler, and scrambler comprises code wheel, axle and code-disc, and slit is arranged on the code-disc, and code wheel and code-disc are loaded on the axle, and code wheel is around on the traction steel wire between the guide wheel.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a general assembly drawing of the present utility model.

Fig. 2 is scrambler figure of the present utility model, and the code wheel that is loaded on a last left end is not expressed.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to Fig. 1 and Fig. 2, code wheel 1 on the scrambler replaces the guide wheel that prior art Central Plains is positioned over this place, make traction steel wire 10 walk around code wheel 1, code wheel 1 and code-disc 3 fixedly be loaded on respectively the axle 2 about the end, slit 4 is arranged on the code-disc 3, there is light-emitting component 5 on code-disc the right, and there is receiving element 6 on the code-disc left side.When the liquid level change of liquid in the storage tank 13, float 7 is followed liquid level and is risen or descend, the traction steel wire 10 that connects float is subjected to displacement thereupon, thereby driving code wheel 1, axle 2 and code-disc 3 rotates together, slit 4 on the code-disc alternately cuts off the light path of coming self-emission device 5, this light signal carries out opto-electronic conversion by receiving element 6, convert the angular displacement of axle 2 rotations to electric impulse signal, by converting digital quantity output after the single-chip microcomputer processing to, this numeral is consistent with actual level value, thereby measures and demonstrate the level value of storage tank to be measured.

The utility model contrast prior art has following advantage: the certainty of measurement height; Simple installation, reliable operation.

Claims

1, a kind of liquid level gauge that is used to measure the large-scale storage tank liquid level, comprise float, floater guiding device, traction steel wire, guide wheel and weight, it is characterized in that, also include the scrambler of forming by code wheel, axle and code-disc, slit is arranged on the code-disc, code wheel and code-disc are loaded on the axle, and code wheel is around on the traction steel wire between the guide wheel.
