Measurement of density of swimmers body includes weighing in air, and submerged in water for processor calculation of density

摘要

The apparatus includes a ladder and weighing device for measuring the bodys weight firstly in air, then secondly when totally immersed in the water of a swimming pool. A processing system is used to determine the density of the body, with knowledge of the two weights, the volume of liquid displaced and the density of the liquid. The system for determining the bodys density includes an apparatus for measuring the bodys weight firstly in air, then secondly when totally immersed in liquid, preferably the water of a swimming pool. A processing system is used to determine the density of the body, with knowledge of the two weights, the volume of liquid displaced and the density of the liquid. The support comprises a ladder (10) extending above and below the water level. The upper end of the ladder includes U-shaped rails which turn back parallel to the main length of the ladder, to be embedded in a support (11) in the side (31) of the s wimming pool. The weighing device (12) is fitted at the bottom of the ladder support (32), and linked to a display (143) mounted on a pillar above the side of the pool.
