Heater strip is installed in groove, offers round rectangle hole, remaining 1/3rd outer wall of main body tube on the housing
The face round rectangle hole, and it is provided with graduated scale on the part in vacuum cylinder body outer wall face round rectangle hole.Work of the present invention
When making, after main body tube is connected by upper valve, lower valve with fluid reservoir, flow of liquid medium enters in main body tube, by vacuum cylinder
Graduated scale show, you can the liquid level in fluid reservoir is correctly shown；When carrying out level gauging at low ambient temperatures, to prevent
Liquid medium solidification in main body tube, is provided with spiral salient, in spiral salient and main body pipe outer wall structure in main body pipe outer wall
Into helicla flute in be fixed with heater strip, and added and vacuum cylinder in the outer of main body tube so that main body pipe outer wall and vacuum cylinder
A vacuum area is formed between body, the heated situation of the cold air interference main body tube in the external world is prevented, when heating wire works start
Adstante febre, its caused heat start to spread on main body tube wall and in vacuum area simultaneously, and then cause main body tube
Generally in the state being heated evenly on outer wall, and spiral salient is located at 2/3rds parts of main body pipe outer wall, and main
Face round rectangle hole at body pipe outer wall remaining three/part so that spiral salient and heater strip are without interference with observation
The sight of liquid level, ensure to read the accuracy of data.
Also include blowoff valve and water injection valve, the blowoff valve, water injection valve are extended through in the top and bottom of housing and master
Body pipe connects.After liquid level test terminates, upper valve and lower valve are closed, is arranged the liquid medium in main body tube by control of sewage disposal valve
Go out, while washed away liquid medium totally by injecting cleaning agent into main body tube in water injection valve, avoid occurring in main body tube
Liquid medium remain, under the influence of one-shot measurement precision.
The material of the main body tube is heat resistant glass.Preferably, main body tube uses heat resistant glass material, it can bear
Drastically difference variation, it is ensured that main body tube keeps its stable physical characteristic under the heat effect of heater strip, avoids because main
There is cataclysm and causes main body tube to burst in temperature between body liquid in pipe medium and main body tube wall, and that improves the present invention uses the longevity
Life.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention adds and vacuum cylinder in the outer of main body tube so that forms one between main body pipe outer wall and vacuum cylinder
Individual vacuum area, the heated situation of the cold air interference main body tube in the external world is prevented, when heating wire works start adstante febre, it is produced
Heat simultaneously start to spread on main body tube wall and in vacuum area, and then cause main body tube outer wall on generally in
The state being heated evenly, and spiral salient is located at 2/3rds parts of main body pipe outer wall, and main body pipe outer wall is remaining
Face round rectangle hole at three/part so that spiral salient and heater strip regarding without interference with observation liquid level
Line, ensure to read the accuracy of data；
2nd, the present invention is after liquid level test terminates, closing upper valve and lower valve, by control of sewage disposal valve by the liquid in main body tube
Body medium is discharged, while is washed away liquid medium totally by injecting cleaning agent into main body tube in water injection valve, is avoided in main body
Occur liquid medium residual in pipe, under the influence of one-shot measurement precision；
3rd, main body tube of the invention uses heat resistant glass material, and it can bear drastically difference variation, it is ensured that main body tube
Its stable physical characteristic is kept under the heat effect of heater strip, avoid because in main body tube liquid medium and main body tube wall it
Between temperature there is cataclysm and cause main body tube to burst, improve the present invention service life.
