<p>The invention relates to a manometer including a round dial (1) and an indicator (2) with a central shaft, characterised in that the dial carries lines (50, 60, 70) defining pressure zones (A, B, C, D), one (6) of these indicating a normal pressure and the others an abnormal pressure. This manometer also carries a temperature scale extending radially from the centre of the dial, so that along the indicator the current temperature reference point then indicates the zone of the compensated pressure. Application to ensuring that a vessel is correctly filled with gas. <IMAGE></p> |
