Ved brug af anlægget til vand, når befugtningspatronen først er forbundet, strømme under tyngdekraftens indvirkning fra flasken 15 til befugtningspatronen 30 via forbindelsesorganerne 25 og 34. Vandet vil herved stige op i befugntingspa-15 tronen 30 og til sidst afbryde luftforsyningen til det niveaufølsomme rør 31.Using the water system, once the wetting cartridge is first connected, under the action of gravity, flow from the bottle 15 to the wetting cartridge 30 via the connectors 25 and 34. The water will thereby rise in the wetting cartridge 30, eventually interrupting the air supply to the level sensitive tube 31 .

Vandet vil fortsætte med at stige i det niveaufølsomme rør 31 og frembringe et undertryk i flaskens luftrum 40. Ved ligevægt 20 vil niveauet i det niveaufølsomme rør 31 være det samme som niveauet i flasken 15. Undertrykket i flasken vil være lig med det hydrostatiske tryk, der er ækvivalent med forskellen i niveauerne imellem vandet i flasken og vandet i befugtningspa-tronen 30.The water will continue to rise in the level-sensitive tube 31 and produce a negative pressure in the airspace of the bottle 40. At equilibrium 20, the level in the level-sensitive tube 31 will be the same as the level in the bottle 15. The vacuum in the bottle will be equal to the hydrostatic pressure. which is equivalent to the difference in the levels between the water in the bottle and the water in the wetting cartridge 30.

Ved ikke-cyklisk svingende, kontinuerlig strømning vil fordampning bevirke, at vandniveauet inden i befugtningspatronen 30 vil falde, og herved vil bunden af det niveaufølsomme rør 31 blive udsat for luft. Noget af vandet i det niveaufølsomme 30 rør vil strømme ud og blive erstattet af luft fra det indre af befugtningspatronen 30. Dette vil medføre en ubalance, således at vandet vil strømme fra flasken 15 igennem forbindelsesorganet 25 og røret 26 samt forbindelsesorganet 24 ind i befugt-ningspatronen 30. Denne cyklus vil gentage sig, efterhånden 35 som vandet i befugtningspatronen opbruges, og som følge heraf vil der blive opretholdt et konstant vandniveau.With non-cyclic, continuous flow, evaporation will cause the water level within the wetting cartridge 30 to fall, thereby exposing the bottom of the level-sensitive tube 31 to air. Some of the water in the level sensitive tube will flow out and be replaced by air from the interior of the wetting cartridge 30. This will cause an imbalance so that the water will flow from the bottle 15 through the connector 25 and tube 26 as well as the connector 24 into the humidifier. This cycle will repeat as the water in the wetting cartridge is used up, and as a result, a constant water level will be maintained.
