Abstract
The utility model relates to a meter-type device, relating to a pneumatic liquid level sensor measuring the height and liquid level, comprising an air supply and a pipe. The pipe is equipped with gas pressure sensor. One side of the pipe is connected with the interior of the liquid; the pipe can be inserted into the interior of the liquid directly; the pipe can be inserted into the interior of the liquid from one side; has the advantages of simple structure, high precision, low cost, and adaptability to working under any environments.
Description
Technical field
The utility model belongs to the meters device, relates in particular to a kind of pneumatic type liquid level sensor of measuring the liquid level height.
Background technology
At present, the liquid level sensor that uses mostly is installed in the scene usually, in the relatively harsher place of some environmental baselines, sensor can't be installed, even can't work, and maintenance also is very inconvenient, so, require to use round-about way to carry out the liquid level of tracer liquid.The known liquid level sensor that is installed in the scene, because near on-the-spot, damage easily, serviceable life is shorter, and failure rate simultaneously, because of the damage of liquid level sensor can not be sent correct liquid level signal, thereby is brought dangerous consequence than higher.Liquid level sensor needs operation at the scene mostly in addition, and a part is not suitable for the place of the working environment of personnel's arrival and then can't measures, and can't safeguard.
Summary of the invention
The purpose of this utility model be to overcome deficiency of the prior art and provide a kind of simple in structure, accuracy rate is high, with low cost, be suitable for the pneumatic type liquid level sensor of in any environment, working.
The purpose of this utility model is achieved in that the utility model comprises source of the gas, pipeline, and pipeline is provided with gas pressure sensor, and an end of pipeline leads to the inside of liquid.Described pipeline can directly insert liquid internal.Described pipeline can insert liquid internal from a side.
The utlity model has simple in structure, accuracy rate is high, with low cost, both can in any environment, work, can realize the advantage of remote tracer liquid liquid level again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises source of the gas, pipeline 1, and pipeline 1 is provided with gas pressure sensor 2, and an end of pipeline 1 leads to the inside of liquid.Described pipeline 1 can directly insert liquid 3 inside.Described pipeline 1 can insert liquid internal from a side.
Source of the gas of the present utility model can be air compressor, pressurized air is provided with gas pressure sensor 2 by pipeline 1, one end of pipeline 1 leads to the inside of liquid 3, the other end be arranged on liquid 3 liquid level above, gas pressure sensor 2 is arranged on the top of pipeline 1, blows in pipeline 1 from top simultaneously, this moment is because the effect of air pressure, liquid 3 in the pipeline 1 will be discharged by the bottom from pipeline 1, and this moment is according to the gaseous tension of measuring, and can indirect calculation go out the height of liquid 3; Pipeline 1 can insert the inside of liquid 3 from a side.
Claims (3)
1, a kind of pneumatic type liquid level sensor comprises source of the gas, pipeline (1), and it is characterized in that: pipeline (1) is provided with gas pressure sensor (2), and an end of pipeline (1) leads to the inside of liquid.
