Abstract: The invention relates to a method for the real-time determination of the filling level of a cryogenic tank intended to house a two-phase liquid/gas mixture, in which at least one of the the level, volume or mass contained in the tank is calculated for the liquid or the gas at each time step. The method includes the use of a thermal model at each time step to calculate the average temperatures of the liquid and the gas in the tank on the basis of the measured pressure differential and at least one of the pressures of said differential; calculation of the change over time in at least the density of the liquid on the basis of the average temperature of the liquid and the pressures in the tank.

Abstract: Method of tracking the performance of an industrial appliance (E), in which an estimate (We) of the quantity representing the electrical power consumed is calculated, in real-time, using the model (M), based on the values of the set (F) of operating parameters of the industrial appliance (E), the difference between the measured value (W) of the electrical power consumed (W) and the estimated value (We) provided by the model (M) is calculated, to obtain the overconsumption value, based on a statistical test on the overconsumption variable, using the distribution of this variable, an overconsumption score is deduced from this corresponding to a probability of overconsumption (p1) and an alarm is triggered if the probability of overconsumption (p1) exceeds a given overconsumption probability threshold (sp1), so constituting an overconsumption indicator.

Abstract: The invention relates to a method for the real-time determination of the filling level of a cryogenic tank (1) intended to house a two-phase liquid/gas mixture, in which at least one of the following variables is calculated for the liquid and optionally for the gas at each time step (t, t+ ?t . . . ), namely: the level, volume or mass contained in the tank (1), whereby, at each time step, the method includes the measurement of the pressure differential (DP=PB?PH) (in Pa) between the upper and lower parts of the tank and at least one of the pressures (PH, PI) of said differential. The invention is characterised in that the method includes the following steps: use of a thermal model at each time step (t, t+ ?t . . . ) to calculate the average temperatures of the liquid (Tl) and the gas (Tg) in the tank (1) on the basis of the measured pressure differential (PB?PH) and at least one of the pressures (PH, PI) of said differential; calculation of the change over time (t, t+ ?t . . .

Abstract: The invention provides a device for dispensing accurately-controlled small quantities of at least one liquid, comprising a liquid supply (L); a gas supply (G), arranged to selectively supply a gas pressure; and a capillary duct (20) adapted to be filled with liquid to be dispensed, and to eject the liquid. The device has a filling configuration wherein liquid from the supply is in contact with an end (20a) of the capillary duct to fill the capillary duct with liquid; and a liquid separation and ejection configuration, in which liquid remaining in the liquid supply is separated from liquid that fills the capillary duct to form a discrete quantity (V) of liquid filling the capillary duct (20) out of contact with the remaining liquid of the liquid supply. The capillary duct, filled with this discrete quantity (V) of liquid then has one end in contact with the gas supply and another end in contact with the atmosphere.
