Working principle According to Archimedes principle of body submerged in a liquid. A rod with a density similar to the measured liquid is suspended by a spring to maintain an equilibrium with its weight. This rod is always submerged in the liquid (not floating on the surface) A variation in the liquid level (1) produces a change in the weight of the rod (partially submerged), which can be measured by the extension or compression of the spring that supports the rod (2). The variation in the length of the spring is transmitted to the indicating needle via a magnetic coupling (3). This...
