Abstract: The paper looks at the solution of a problem concerning the number of movements linked to weighing frequencies, which consists of developing the device for measuring the freight mass directly attached to the dump truck. According to the concept of using hydraulic sensors the recommended system is worked. This consists of a hydraulic sensing system with higher pressure oil pipelines of both the left and right pipe-line, hydraulic ram hydro pressure pipelines, a weight thorned petroleum pressure gage, a three-run distributive tap, an hydraulic ram for an oil tap, an oil pump, a low pressure gas pipeline, a rear pipeline and an intermediate stream. Oil pump is available with a working valve. The hydraulic sensors of left and right longerons are linked in parallel via a three-running dispensing tap and a bilateral action valve to a hydraulic high-pressure oil pipeline. The hydraulic sensors for the weighing of freight equipment operate in a similar way to hydraulic ram. The dependence which enables to determine the main device parameters for the left and right sensors based on the passed quantity of working flubid, Reynold number and pressure decreases in all elements of the hydraulic system, such as the internal diameter of the oil pipeline for liquid supply. The dependence is provided. The proposed device can be used in specific practical application in combination with the system for fixing the freight weight transported
