Abstract
A measurement device comprising a curved container containing a liquid, a first indicator that is less dense than the liquid, and a second indicator that is more dense than the liquid, where the liquid substantially fills the container so that the position of the first indicator and/or second indicator in the container relative to the reference indicia may indicate an angle-related property of the device.
Claims15
A measurement device comprising:
- a curved container containing, the curved container following a circular path, wherein the circular path extends along an arc, and
- a liquid, and
- a first indicator that is less dense than the liquid, and
- a second indicator that is more dense than the liquid, where the liquid substantially fills the curved container;
- wherein the first indicator is free to move in the liquid to its highest local point relative to the gravitational vertical axis as determined by the confines of the container, and the second indicator is free to move in the liquid towards its lowest local point relative to the gravitational vertical axis as determined by the confines of the container;
- and wherein the measurement device further comprises reference indicia arranged relative to the container so that the position of the first indicator and/or second indicator in the container relative to the reference indicia may indicate an angle-related property of the device.

A kit comprising:
- a curved container containing a liquid, a first indicator that is less dense than the liquid, and a second indicator that is more dense than the liquid, where the liquid substantially fills the container, wherein the first indicator is free to move in the liquid to its highest local point relative to the gravitational vertical axis as determined by the confines of the container, and the second indicator is free to move in the liquid towards its lowest local point relative to the gravitational vertical axis as determined by the confines of the container;
- and
- a plurality of frames, wherein the container is removably attachable to each of the plurality of frames;
- wherein each of the plurality of frames includes reference indicia so that when each of the frames is individually attached to curved container, the reference indicia are arranged relative to the container so that the position of the first indicator and/or second indicator in the container relative the reference indicia may indicate an angle-related property of the container.
