ABSTRACT:
A method of and device for gauging a liquid meter, the device comprising an enclosure containing a piston and hydraulically connectable to the measuring member of the meter, the piston being a plunger piston with a cross-section smaller than that of the enclosure and being mounted for a sliding motion in fluid-tight relationship through a wall mounted transversely within the enclosure to there define two fluid-tight capacities between which the piston moves in plunging relationship.
