Abstract
Abstract The invention relates to a water separator for a gas analyzer, comprising a tube (12) for passing a gas sample into the water separator, wherein water separation is effected in a tubular passage by dividing the flow into two partial flows. The wall or walls (3) of a first tubular passage (17) are made of a porous material, readily permeable to gas, and this main flow, which has penetrated the wall, is passed into a second tubular passage (4) and via a tube (10) on to measuring sensors (5 and 6) but the water, which is not able to penetrate the porous wall of first passage (17), is passed along with a minor amount of gas down a passage (17, 13) into a water receiver (15) and this many times lesser side flow further via a tube (14) into a third tubular passage (16), through its porous wall (3) into a fourth tubular passage (18) and via a tube (11) through a flow throttle (7) on to a pump (8).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
A water separator for a gas analyzer, comprising a housing, a first chamber disposed within said housing, a second chamber disposed within said housing, a wall formed of a gas permeable and liquid impermeable material separating said chambers, means for introducing a gas sample containing a liquid into said first chamber with a first portion of the gas passing through said wall to the second chamber and a second portion of the gas and said liquid remaining in the first chamber, means for flowing said first portion of the gas from the second chamber to a measuring unit, a receptacle mounted on the housing, a first conduit connecting said first chamber and said receptacle for conducting said second portion of said gas and said liquid to said receptacle, and a second conduit connecting the upper end portion of said receptacle with a source of vaccum for removing said second portion of said gas from said receptacle.
Claim 2
Dependent Claim
156 words
A water separator for a gas analyzer, comprising a housing, a first chamber disposed within said housing, a second chamber disposed within said housing, a wall formed of a gas permeable and liquid impermeable material separating said chambers, means for introducing a gas sample containing a liquid into said first chamber with a first portion of the gas passing through said wall to the second chamber and a second portion of the gas and said liquid remaining in the first chamber, means for flowing said first portion of the gas from the second chamber to a measuring unit, a receptacle mounted on the housing, a first conduit connecting said first chamber and said receptacle for conducting said second portion of said gas and said liquid to said receptacle, and a second conduit connecting the upper end portion of said receptacle with a source of vaccum for removing said second portion of said gas from said receptacle.
Claim 3
Dependent Claim
39 words
