Liquid, is stirred with glass bar.The solution prepared is poured into reservoir 42, in order to accelerate experimentation, then respectively to soap pipe
11 and collecting pipe 32 in be separately added into a certain amount of soap lye, soap pipe 11 liquid level and reach in the lower edge of air inlet 12, collecting pipe 32
Liquid level reaches the lower edge of photoelectric sensor transmitting terminal 3 33.When starting to occur upper soap lye Deng the inwall of soap pipe 11, startup program, weight
Hammer 21 is automatic in the presence of instruction to be declined with being lifted, and causes liquid level regularly fluctuation, soap-film is constantly produced in soap pipe 11, on
When position machine records that liquid level rises to overfall 26 in instantaneous delivery value, liquid storage pipe 22 in real time, soap lye is spilled in collecting pipe 32, when
When liquid level exceedes photoelectric sensor transmitting terminal 3 33, the soap lye in collecting pipe 32 is pumped to reservoir 42, so as to form dynamic
Circulation, this process is not required to artificial interference, all realized automatically by program, when stopping experiment, and weight 21 stops impacting liquid level,
Complete whole measurement process.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also should be regarded as with retouching.
