Inverted isosceles triangle, division board 10 is connected to midline and division board 10 lower end and the baffle plate 18 of the above-below direction of baffle plate 18
Lower end concordant.In addition, the first cavity gas collection unit 9 of other similar structures forms and the second cavity gas collection unit 11, also may be used
To realize the purpose of the gas collection of the present embodiment, here is omitted.
Enumerator 17 is connected with centrally-pivoted axle 8, and for counting to the rotation situation of centrally-pivoted axle 8, enumerator 17 can
Think mechanical counter, enumerator 17 can also be sensor counter.Mechanical counter can be by centrally-pivoted axle 8 no outer
Mechanical Driven in the presence of power, certainly, when the first cavity gas collection unit 9 and the second cavity gas collection unit 11 drive centrally-pivoted axle 8
Without mechanical counter, but reed or mercoid switch one class on centrally-pivoted axle 8 can also be may be mounted at picture during rotation
Sensor, then an external electronic logger just can record the accumulation gas of generation.This gas counter 17 can set
Count into the correction system that can connect readable.
The operation principle of the gas flowmeter of the controlled resolution of the present embodiment is：
Gas to be measured connects air inlet pipe 1 by external pipe and is passed in the liquid medium 3 in hermetic container 4, and shape
Become the final liquid level floating by close cavity bottom from air inlet 12 of bubble 2, be then introduced into out subsequently into gas-phase space 13
Trachea 5.
Bubble 2 floats from air inlet 12 and then is temporarily collected in the cavity of back-off, the cavity body of back-off be a pair downward
The triangular cavity gas collection unit (the first cavity gas collection unit 9 and the second cavity gas collection unit 11) tilting, two gas collection units
Connected by balance cell body 7, and swung to both sides by centrally-pivoted axle 8, the division board 10 between two gas collection units is located at balance
The centre of cell body 7, in the separation realizing two gas collection units.
As shown in figure 3, when gas collection unit is in left and right sides non-horizontal position, the gas that enters from air inlet pipe 1 will be by
It is collected in one of gas collection unit (the first cavity gas collection unit 9 in left side), in this position, balancing cell body 7 is to the left
Tilt, and division board 10 division board bottom 16 is then on the right side of air inlet 12, in this way it can be ensured that air inlet can enter the first chamber
In body gas collection unit 9.
As shown in figure 4, when gas collection unit because buoyancy is converted to another one gas collection unit (second cavity on right side
Gas collection unit 11) when, two gas collection units swap work, and the gas being before collected in the first cavity gas collection unit 9 is released
After putting, bubble will be collected in the second cavity gas collection unit 11, and therefore, division board 10 division board bottom 16 moves to another
Side is it is ensured that gas enters in the second cavity gas collection unit 11.
First adjusting knob 15 and the second adjusting knob 16 are located at the left and right two ends balancing cell body 7, and adjusting knob can control
The position that gravity regulator 6 rolls in balance cell body 7, different positions produces different collection tolerance, to realize resolution
Change.The variation of the position of gravity regulator 6, so that the buoyancy that in two gas collection units, the accumulation gas of setting produces pushes away
Dynamic gas collection unit rotates around centrally-pivoted axle 8 so that gas collection unit tilts, and quick changing at two is changed between gas collection unit.One
Denier gravity regulator 6 moves past center, i.e. the vertical position of air inlet 1 and centrally-pivoted axle 8, and gas collection unit will be fixed up,
Until one of enough gas accumulation again to two gas collection units, when a gas collection unit trapping and accumulation gas
During body, the gas collection unit of previous captured gas can discharge gas to control gravity to adjust machine 6 to be rolled to contrary position, this
Power comes from accumulation gas and repeatedly exchanges and produces during gas collection unit.Above-mentioned step makes in each gas collection unit precisely
Accumulation gas conversion be repeated adjust, and do not have gas in transformation process and miss.
The exchange each time of the gas collection unit of this gas flowmeter is corresponding to a gas flow pre-setting, this gas
Flow will be recorded by enumerator 17.
The gas flowmeter of controlled resolution of the present utility model can adjust lifting force, to change measuring unit
Resolution, to adapt to the measurement of gas with various range of flow, meanwhile, can farthest avoid letting out of gas in measurement process
Dew is to ensure the accuracy measuring.Specifically, gas collection cavity (the first cavity gas collection unit 9 and the second cavity collection of a pair of balance
Gas unit 11) continual exchange trapping and release gas to be measured can be carried out by swinging of central pivot 8；First
The resolution of cavity gas collection unit 9 and the second cavity gas collection unit 11 mensure gas is adjusted by gravity regulator 6, and
Preset before measuring gas flow；The enumerator 17 of gas yield is counted by the rotation of centrally-pivoted axle, meter
Number mode includes mechanical count and sensor counts.
Embodiment of the present utility model is given for the sake of example and description, and is not exhaustively or to incite somebody to action
This utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
See.Select and description embodiment is in order to principle of the present utility model and practical application are more preferably described, and make this area
Those of ordinary skill is it will be appreciated that this utility model is thus design is suitable to the various embodiments with various modifications of special-purpose.
