Hi there,

Archimedes' principle states that a body wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced.

A level or density instrument is sensitive to the apparent weight of an immersed displacer.

If the cross-sectional area of the displacer and the density of the liquid are constant, then a unit change in level will result in a reproducible unit change in the apparent weight of the displacer.

The important thing to note is that the displacer must be heavier than the process liquid.

So first of all, you need to work out the total volume of the displacer chamber when filled with the process liquid. If it is a cylinder - Volume = Height x pi x Radius^2

You can then convert that to mass with the SG of the process liquid. (Mass = Volume x Density)

You would then speak to your supplier to select a displacer that is heavier than the process liquid mass that you calculated.

Regards,

Craig
