<p><P>PROBLEM TO BE SOLVED: To provide a production method in which mixing of foreign matters and contaminants is sufficiently reduced, and a resin composition solution with a reduced amount of foreign matters and contamination is efficiently obtained. <P>SOLUTION: The resin composition solution is produced by using a tank 10 equipped with a non-contact type liquid level meter 40 that measures the liquid surface in a non-contact way with the liquid contained inside. The liquid level meter 40 adopts, as a detecting means for detecting the liquid level position in non-contact manner, anyone of the measurement of the liquid weight, use of microwaves, use of a laser, use of ultrasonic, and use of radiation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
