Abstract

PURPOSE:To automatically check the liquid quantity stored in an accumulator, by connecting to a processing unit a pressure measuring device for measuring the operating pressure of the accumulator, and a liquid level measuring device provided in a liquid tank of a hydraulic pressure circuit. CONSTITUTION:An operating liquid is filled in a liquid tank 1. A level H of the surface of the liquid as a reference level is measured by a liquid level sensor 5. The operating liquid in the liquid tank 1 is supplied in a pressed condition to a hydraulic pressure circuit 2 by a pump 18. At this time, a gas enclosing pressure in a plug 7, namely, a liquid pressure is measured by a pressure sensor 6. The quantity of the liquid flowing into an actuator 4 is measured by a displacement meter 13 to be inputted to an external signal inputting/outputting device 14. Accordingly, the measured value of the liquid level sensor 5 and that of the displacement meter 13 are added together in a central processing unit 15, thereby to obtain a corrected liquid level. By comparing the corrected liquid level with the reference level, a stored volume or quantity in an accumulator is automatically indicated by a display device 17.
