A gas/liquid accumulator (8) for a level difference measuring apparatus based on the measurement of the hydrostatic head of a liquid column and particularly intended for use in a piece of construction equipment, said equipment having its boom system (2, 4) equipped with a liquid-filled hose (14) extended between a point (6) separate from the boom of the equipment and the pivotal fastening joint of said attachment, one end of said hose being provided with a transducer (5) capable of measuring the hydrostatic pressure prevailing in said liquid-filled hose (14). The gas/liquid accumulator comprises a liquid compartment (9) communicating with said hose (14) and a gas compartment (10), said compartments (9, 10) being separated from each other by means of a resilient diaphragm (8c). The invention also relates to a level difference measuring apparatus utilizing said gas/liquid accumulator (8). |
