DEVICE FOR CONTROLLING THE CHARACTERISTICS OF A COOLING LIQUID AND METHOD USING SAME |
摘要 |
The invention concerns a device and a method for controlling the protective temperature and alkalinity reserve of a cooling liquid, obtained by diluting an anti-freeze compound containing carboxylic compounds. The device comprises at least a refractometer, pH paper and a test tube in a portable closed chamber. The invention is characterised in that the test tube is graduated in protective temperature, each division corresponding to a volume X of cooling liquid having a known protective temperature varying with the dilution rate C of said anti-freeze compound in the water, and a minimal required alkalinity reserve, X corresponding to (10 x VA)/(RA x C), VA being the volume of acid, RA the alkalinity reserve and C the anti-freeze compound concentration in the cooling liquid, expressed in percentage. |
