Abstract:
1. A device for manufacturing a gas dissolved solution, comprising: a gas supply source having gas flow rate adjusting means; a gas dissolver in which gas and solution are to be introduced from the gas supply source; solution flow rate adjusting means for controlling the flow rate of the solution introduced into the gas dissolver to be constant; and a take-out pipe for taking out a solution from the gas dissolver, the manufacturing device further comprising: a measuring device for measuring the quantity of gas bubbles existing in the take-out pipe; and a control device for computing the gas concentration of the solution based on a relational expression between the quantity of bubbles and gas concentration measured preliminarily under a condition that the solution flow rate and gas flow rate are constant and a measured value from the measuring device and controlling the gas flow rate adjusting means and/or the solution flow rate adjusting means based on the computation result.
