The watertrap itself includes “water fuses” in both the “measurement” and the “drainage” paths,
consisting of a material that swells when getting wet (when the reservoir is full or when fluid penetrates
the separation filter and enters the “measurement” path) and blocks the respective path at the inlet of
the unit. Once the “water fuses” are blown, any passage of fluid is blocked and the gas flow resistance
increases so that an occlusion is detected.
