Abstract

1. A method of monitoring the extraction of gas from a hydraulic circuit comprising a reservoir (10, 23) the high point of which is connected to a vacuum pump (12, 32) in which the gas extraction operation is carried out maintaining the vacuum above the liquid substantially constant, characterized in that the gas extraction operation is carried out maintaining in addition, the temperature and the exposed surface area of the liquid in the reservoir (10, 23) substantially constant, and in that the gas extraction is monitored by measuring the instantaneous flow of gas extracted by the vacuum pump (12, 32), this flow being a function of the total percentage of gas, dissolved and in suspension, contained in the liquid at the same instant.
