   Zur Lösung dieser Aufgabe wird gemäss vorliegender Erfindung in der Flüssigkeit ein Verdrängerkörper angeordnet von solchem Volumen, dass das Produkt seines Volumens und seines kubischen Ausdehnungskoeffizienten gleich ist der Differenz der Produkte von Volumen und Ausdehnungskoeffizient des Gefässes und der Flüssigkeit. Wenn die Aufgabe so lautet, dass bei einer Temperaturänderung nicht der Druck oder der Flüssigkeitsstand unverändert bleiben soll, sondern einen bestimmten vorgeschriebenen Wert erreichen soll, so kann dies

  Device for compensating the influence of temperature on the liquid level in one. Vessel, on the internal pressure of the liquid-filled vessel or the like.



   In the case of liquid-filled vessels, the task is often to keep the level of the liquid at a certain level despite the changing temperature, for example to make the height of the liquid column in a narrow tube connected to the vessel dependent on the temperature or, if it is an all-round one closed vessel, completely filled with the liquid, is to make the internal pressure independent of the temperature of the vessel and the liquid.
 EMI1.1
 instruments that have liquid containers and in which the liquid level or pressure should be kept independent of temperature.



   To solve this problem, according to the present invention, a displacement body is arranged in the liquid of such a volume that the product of its volume and its cubic expansion coefficient is equal to the difference between the products of volume and expansion coefficient of the vessel and the liquid. If the task is such that when the temperature changes, the pressure or the liquid level should not remain unchanged, but should reach a certain prescribed value, then this can be done
