The operating process of this from the electronics soap film flowmeter of movable property bubble is as follows：First, soap lye, edge are added from the top of soap pipe 11
Tube wall annular is instilled, it is ensured that soap inside pipe wall uniform wet.Liquid Level Regulation System is moved up and down, weight is located at liquid level top, and
And soap intraluminal fluid position is less than air inlet lower edge, now, stop liquid feeding, as shown in Figure 3.Liquid Level Regulation System is due to the work of magnetic force
It is aerial with being suspended in.Tested source of the gas is connected with soap pipe air inlet by flexible pipe, is applied to around interface with soap lye, there is no bubble to produce
Raw explanation air-tightness is good.Magnet coil is controlled to power up by host computer procedure, or hand switch is powered up to magnet coil, electromagnetism
After coil energization, magnetic field is produced, attract pull bar to move down, drive weight to immerse in soap lye downwards, liquid level rises, when soap pipe
When interior liquid level rises to soap pipe air inlet upper edge, the gas of air inlet is blocked in outside, it is impossible to enter, and forms fluid-tight,
As shown in Figure 4.Give magnet coil power-off, weight rises together with pull bar, liquid level declines in liquid storage pipe, the liquid level in soap pipe with
Reduction, in this process, the pressure to be formed as liquid level declines of gas that outside blocks reduces, under gas pressure effect
Constantly inwardly stretch, gas-liquid interactive interface gradually increases, form a thin layer soap-film, under the promotion of gas, move up, such as scheme
Shown in 5.When soap-film is by lower photoelectric sensor, due to the interception of soap-film, block what photoelectric sensor transmitting terminal sent
Infrared light, makes receiving terminal to receive, and produces low level signal；Soap-film is continued to move up, and when leaving, infrared light again can be by
Receiving terminal is received, and forms high level signal.Switching of the external circuit by recognizing high and low level reaches record soap-film and starts to set out
Time.Similarly, the photoelectric sensor on top also experiences identical process, and difference is that upper photosensor record is
Soap-film terminates the time.Both differences are the time required for soap-film is accumulated by this segment body, so as to be calculated the average of gas
Flow.By after upper photosensor, through time delay after a while, magnet coil continues to power up soap-film, is produced next time
Bubble process, so as to reach from movable property bubble, goes round and begins again, and forms a kind of electronics soap film flowmeter from movable property bubble.
In specific implementation process, with the gas flow of the flow measurement dead axle flow fan.From internal diameter 15.5mm, external diameter
18.0mm, overall length 443mm, are nominally the soap pipe 11 of 50mL.Soap pipe air inlet 12 passes through reducing and flexible pipe with aerofoil fan outlet
Connection.40g liquid detergent foaming agents are weighed with 500mL beakers, by liquid detergent:The mass ratio of deionized water is 1:10 are configured to soap
Liquid, is stirred with glass bar.Soap inside pipe wall is drained to along glass bar from the top of soap pipe 11, glass bar is clockwise along soap inside pipe wall
Rotate, reach the purpose of soap lye uniform wet soap inside pipe wall.Liquid Level Regulation System is put to extreme lower position, makes liquid level in soap pipe 11
Less than the lower edge of soap pipe air inlet 12, Liquid Level Regulation System is constantly lifted, untill soap lye face is exposed in the bottom of weight 21, then
It is finely adjusted, weight 21 is slightly above liquid level in liquid storage pipe 22.The supply voltage of magnet coil 19 is 6V, and rated current is 3A, is given
Magnet coil is powered, and pull bar 17 is moved down, and compresses upper springs 18, promotes weight 21 to immerse in soap lye downwards, liquid storage pipe
In 22 liquid level rise, liquid level also rises therewith in soap pipe 11, when liquid level rise on soap pipe air inlet 12 along when, charge air flow quilt
