    Abstract: A method for determining an average temperature of a fluid in a closable container (1) comprising: providing a duct (4) with first opening (11a) and second opening (11b), positioning a flow preventing element (7) in the duct (4), positioning a density sensor (3) or first pressure sensor (3) inside the duct (4) or container (1), attaching the duct (4) to a container outside wall, stabilizing a temperature of the duct wall (10) to a constant reference value, determining a difference between a first pressure of the fluid on one side and a second pressure of the fluid on the other side of the flow preventing element (7), measuring a local density of the fluid by the density sensor (3) and/or a local pressure by the first pressure sensor (3), and deriving the average temperature from the local differential pressure, the local density and the reference duct temperature.

    Abstract: A method and device for operating a fluid-insulated electrical apparatus (1) are disclosed. The insulation fluid (10) of the electrical apparatus (1) comprises at least two fluid components (A,B) which are a priori ingredients of the insulation fluid (10). The method comprises the step of carrying out at least one optical measurement and/or at least one gas chromatographic measurement on the insulation fluid (10). Using this measurement or these measurements or at least one additional measurement on the insulation fluid(10), a first concentration (cA) of the first fluid component (A) and a second concentration (c B ) of the second fluid component (B) are derived. Then, using the first concentration (c A ) and the second concentration (c B ), and, advantageously, a dielectric breakdown strength E bd of the insulation fluid (10), an operating state (O) of the electrical apparatus (1) is derived.

    Abstract: A method and device (1) for estimating a density value ρ m indicative of a true density ρ or for estimating a viscosity value η m indicative of a true viscosity η of a fluid (F) is disclosed. For this, a first resonance frequency f R of a first mechanical oscillator (10) in a reference volume (RV) and a second resonance frequency f F of a second mechanical oscillator (20) in contact with the fluid (F) are measured. The estimated value ρ m or η m is then derived using these resonance frequencies f R and f F . During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid (F) is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid (R). Thus, fundamental errors in the derivation of the estimated value ρ m or η m are reduced and the estimated value becomes more reliable.
