Abstract

There is provided a device (2) for measuring total gas content in a liquid where said liquid is contained in a closed system (1), the device (2) comprising means for isolating a portion of the liquid from the system in an analysis container (4), means for decreasing the pressure in the analysis container, a gas collecting space (8) in fluid connection with the analysis container and arranged above the analysis container (4) such that gas will be collected in the gas colleting space (8) such that an interface (12) between the liquid and the gas may form in the gas collecting space (8) , a first electrical pole (9) being elongated and arranged in the gas collecting space (8) such that it extends through the interface (12) between the liquid and the gas, and a second pole (10) formed by the inner surface of the gas collecting space (8) , means for determining the capacitance between the first pole and the second pole, such that the determined capacitance is related to the volume of gas collected in the gas collecting space (8).
