METHOD AND DEVICE FOR DETERMINING A FLOW VOLUME GUIDED THROUGH A WATER PIPE, PARTICULARLY FOR LIMITING THE FLOW VOLUME IF A PREDETERMINED SET FLOW VOLUME IS EXCEEDED

摘要

The present invention relates to a kind of determining airflow volumes to be conducted through water pipe, if being more than in particular for the limitation scheduled flow volume of airflow volume. According to the present invention, it includes that solvent and component dissolve wherein that chamber (17,39), which is provided with solution,; The concentration of the component of dissolution is solution in room (17,39); The room is fluidly connected to corresponding water pipe (21), to be moved back into or water pipe (21) when the water pipe (21) of the lateral flow of the open electric circuit of the water pipe (21) when room (17,39) are moved, thus, the concentration of solution is reduced in chamber (17,39) via open flow circuit, the flow volume determines water pipe (21), or more particularly limit, according to the concentration of solution in chamber (21) 0, (21) 1.
