FIELD: fire-fighting, particularly special adaptations of indicating, measuring, or monitoring equipment.
SUBSTANCE: fire-fighting device comprises cylinder filled with fire-extinguishing composition and means to indicate gas losses owing to gas leakage from the cylinder. The means comprises capacitive sensor calibrated in temperature range below and above critical carbon dioxide temperature.
EFFECT: increased reliability of gas leakage determination without cylinder weighting.
