The glass overstatement generally used the measurement of fluid density measures, but when physical property of fluid is each different, then
It needs to select different glass overstatements according to the requirement of Surveying Actual Precision, for example, to measure density range is about 650kg/m3
~2000kg/m3Fluid density when, since the measuring range of different glass overstatements is extremely limited, that is, need at least 39 glass
Glass overstatement could be measured accurately, although the scale division value in some glass overstatements can reach 2/10000ths and ten thousand currently on the market/
Between five, but in real work, first, this high-precision glass overstatement is not continually to use, generally used in work
Work intensity meter be scale division value be one thousandth, and use cost is higher, it is extremely inconvenient to operate, second is that this high-precision
Glass overstatement in order to realize high-precision, generally require scale division value being made thin, this makes this high-precision glass overstatement
Measuring limit range is extremely limited, easily beyond measuring range during measurement, so as to be measured using branched glass overstatement
Corresponding measurement task could be completed, operation is extremely inconvenient, third, glass overstatement is in use, the weight of float is smaller, in reality
Any one in the work of border comes from motive power caused by outside environmental elements can be to the stable state of glass overstatement
It has an impact, such as the flowing of wind, the variation of liquid tension and the vibration on ground etc. can make glass overstatement by partial load,
Balance is not achieved with gravity in buoyancy in testing liquid, affects the accuracy of reading.

The present invention also provides a kind of measuring method for being used to measure the densitometer of fluid density using this, including following step
Suddenly：
Step 1：Testing liquid is provided：Testing liquid is contained in container；
Step 2：Densitometer is vertically put into step 1 testing liquid, measurement body 2 is made to submerge in testing liquid；
Step 3：Observation of steps two are put into the densitometer in testing liquid, when densitometer is stablized, reading and testing liquid
The reading on corresponding fluid level scale 4 that liquid level flushes obtains and measures the bulking value that body 2 is immersed in testing liquid；
Step 4：Bulking value in the immersion testing liquid of body 2 is measured according to step 3, is read from density scale 3 to be measured
The density value of liquid.
The density range that survey crew pre-estimates the liquid according to the physical property of testing liquid first is surveyed, so i.e. head
The measurement range first reduced, then weighing suitable mass, to be contained in measurement internal, then densitometer is put into testing liquid,
Densitometer is made to submerge in testing liquid, therefrom reads the volume that densitometer is submerged into testing liquid, is selected further according to the bulking value
With the density scale of different scale division values, the range of measurement is further reduced in this way, is directly read from density scale to be measured
The density value of liquid so as to reach simplified measurement process, can be measured accurately using a densitometer and be obtained in larger survey
Density value in the range of amount facilitates operating personnel's use, more fast, meanwhile, measurement body is larger compared to identifying body volume, weight
Measure heavier, the center of gravity of densitometer makes densitometer be easier to stablize and keep the flat of buoyancy and gravity in testing liquid in lower part
Weighing apparatus, it is smaller by outside environmental elements, measurement accuracy is improved, in addition, can also measure in body being contained at any time as needed
The weight of mass is replaced, and to meet different use demands, is convenient to use, and on the other hand, density scale can live
It is dynamic to replace, so as to make the measurement range bigger of densitometer.
