In this paper, a hydrostatic force measuring device is developed which is a simple and inexpensive measuring device. The need for metering occurs in several ways. By measuring, we measure the measured results with the measuring unit. The device has the ability to measure in laboratory conditions, but also in the field. The paper is conceived in several units where in the introduction briefly describes the Pascal law, the effect of force on the surface, the pressure and the principle of the connected vessels. In the second embodiment, the force sensors used in the measurement are shown. The third unit shows the structure of the hydrostatic device and the two configurations of which the optimum is selected. In the fourth, there is a calculation of the hydrostatic device. The fifth unit explains how to make devices from individual parts such as cylinder, clip, cover, connector for measuring instrument, seals and working fluid. The sixth unit contains laboratory equipment that is connected to the unit. Seventh unit shows laboratory measurements where tables and diagrams of pressure, time, force and temperature are found. The final section is a conclusion of a work that illustrates the full work of the hydrostatic force measuring device.
