Produce, cause use cost high；Particularly in some special operation condition, such as HTHP, low medium proportion
Or under several simultaneous environment of operating mode, it applies weak effect.
The solution bill of existing issue includes: 1, increase wall thickness, and the method that inside adds support, although floating
Sub-compressive property strengthens, but its weight is also significantly increased, it is difficult to adapt to high pressure, in low Media density
Operating mode；2, reserve aperture at buoy top, make inside and outside float isobaric, but the easy feed liquor of float sinks.
Due to the limitation of the technical scheme of existing float, constrain the range of application of liquid level gauge, increase and use
And maintenance cost, reduce operating efficiency.
