Abstract: Means indicating displacement of a coil spring comprises a flexible tube having one closed end and partially filled with a liquid forming a meniscus in the tube. The liquid-containing portion of the tube is coiled between adjacent convolutions of the spring and in an abutting relationship therewith. A scale means is provided adjacent to the meniscus in said tube for determining change in position of the meniscus as the spring is compressed or extended.
