Improvements in hydrostatic dynamometers, in which the compressive or tensile force to be measured is transformed by means of a piston that moves in a cylinder or a membrane in a hydrostatic pressure that can be read by a manometer, possibly located at distance, characterized in that a device is provided by which at each discharge of the pressure gauge and the piston or membrane a complementary automatic filling of liquid occurs for example when a quantity of liquid has escaped as a result of a lack of tightness.
