Abstract
A device determines the weight of a hydraulic accumulator () during its operation in a hydraulic facility. A pressurised liquid is introduced into a pressure vessel at least partially filled with a gas. The pressurised liquid compresses the gas and is stored in such a way that when it leaves the accumulator () hydraulic energy is emitted to the facility. The respective current weight of the hydraulic accumulator () is detected by a weighing device () applied to the hydraulic accumulator ().
