    Abstract: A method and equipment for determining (measuring) the level/height, h1 - hx, of one or more interfaces between two or more fluid phases of different density that are contained in a vessel, tank (1) or the like. The position (the level) of the different interfaces in a tank (1) is determined by measuring the pressure and thus indirectly determining the density of the fluid in the tank over the height of the tank by using a pressure measuring rod (2) equipped with pressure sensors (3) which is positioned in and extends over the height of the tank (1). For determining the interfaces, a mathematical model or algorithm is used which calculates how the density and hence the pressure vary over the height of the tank as a function of the fluid properties of the respective fluids in the tank, the interface, on the basis of the density being the same within each layer of the respective fluid, being defined as a respective point (level) at which the density changes from one layer to the next in the tank.

    Abstract: A method for the operation and control of gas filling from a filling station to a receiver is comprising actively controlling essential filling variables within the receiver such as temperature, pressure, and density of the gas; continuously updating estimates of the filling variables based on filling station side measurements interpreted using physical and thermodynamic relations as to make the variables available even when the receiver is not communicating with the filling station in so-called non-communication fueling; and continuously updating the estimated capacity of the receiver based on station side measurements in a non-communication fueling.

    Abstract: A method of controlling the annular pressure in a well during a well construction operation. The operation comprises pumping a fluid down a tubing located within the well and extracting the fluid that flows back through an annulus within said well and surrounding the tubing. The method comprises defining a set pressure pref, determining a desired extraction flow rate qc of fluid from said annulus in dependence upon the set pressure pref and a pumped flow rate into the annulus, and configuring an extraction path to achieve said desired extraction flow rate.

    Abstract: A plant for storing and supplying compressed gas comprises a storage tank (1) for gas, at least one pressurization tank (2) for gas and a buffer tank (3) for a pressure support fluid to be filled into or evacuated from lower portions of the storage and pressurization tanks. The lower portions of the storage and pressurization tanks are communicating with the buffer tank via fluid flow lines (4, 5) to fill fluid during supplying from and pressurizing gas in the plant, and a flow line (7) for evacuating fluid during refilling of the pressurization tank. According to a preferred embodiment the lower portions of the storage and pressurization tanks are communicating with one another via a fluid flow line (6) to exchange fluid between the storage and pressurization tank, whereas gas being pressurized in the pressurization tank is moved into the storage tank via a gas flow line (8) communicating the pressurization and storage tanks with one another, the gas flow line being situated between upper portions of the pressurization and storage tanks.
