<p>A filter dehydrator for sensing the presence of and separating free water in a transient flow of fluid comprising an inlet and an outlet for the fluid, a mass of water absorptive cellulosic fibers 34 disposed between the inlet and the outlet and surrounded by a rigid porous barrier 35, a filter medium 36 upstream of the absorptive mass for removing solid particles that would block the active surface of the mass and for dispersing water droplets in the fluid. The fibre mass 34 is formed from water-insoluble cross-linked carboxymethyl cellulose fibres which swell in the presence of free water. The barrier 35 may consist of four layers of polyvinyl chloride coated fibre glass mesh screen. <IMAGE></p> |
