ABSTRACT:
In an exemplary embodiment, the liquid pressure to be measured is in a liquid container with an inner tube forming a measuring cell arranged in an outer tube, which measuring cell can be filled in part with a liquid and in the remainder with a gas. A conduit that can be filled with the liquid leads away from the measuring cell, which conduit is open on its end facing away from the measuring cell and can be directly connected with the fluid in the liquid container. A transducer for generating an electric magnitude which corresponds to the gas volume in the measuring cell is arranged in the measuring cell. A channel is left free between the outer tube and the inner tube for the passage of the fluid. The inner tube is closed on its end facing away from the measuring end of the pressure transducer.
