METHOD OF CHARGING HIGH-PRESSURE BOTTLES WITH GAS Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: prior to feeding the gas to bottle, is shall lose its weight; to this end, it shall be submerged in liquid whose density provides for zero buoyancy of bottle or it shall be sunken in liquid with the aid of weight; in this case, zero buoyancy is ensured due to compensating reservoir secured to bottle; water is forced out of this reservoir; mass of gas fed to bottle is checked by weighing it in the course of charging. Weighing of high accuracy is ensured because measuring system determines mass of gas only, without masses of bottles. EFFECT: high accuracy of determination of mass of gas. 3 cl, 1 dwg
