Abstract
An encapsulated measuring device is described which includes a hollow body, a scale defining a measuring direction, and a sensing unit disposed to move along the scale within the hollow body. An entrainment member is pivotably secured to the sensing unit and extends out of the hollow body. Sealing members provide a seal between the movable entrainment member and the hollow body, and these sealing members protrude beyond the hollow body so that liquid in the hollow body can flow down onto the sealing members and out of the hollow body through openings between the sealing members and the entrainment member. Because the pivotable articulation allows the entrainment member to be adjusted with respect to the sensing unit, the angle at which the entrainment member protrudes from the hollow body may be adjusted according to the requirements of the individual installations. The configuration of the sealing members allows fluid to drain from the hollow body for a range of orientations of the entrainment member.
