  • Patent number: 4886528
    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).
