Separated solids monitoring system

A separated solids monitoring system comprising a pressurised solids accumulator for receiving separated process solids, a weighing platform located inside the accumulator and arranged to carry process solids as they settle in the accumulator, a force transducer located inside the pressurised accumulator and mechanically coupled to the weighing platform to provide a weight signal which is a measure of gravitational force on the weighing platform, and mechanically based pressure compensation means integrated within the force transducer comprising a load cell contained in a sealed chamber filled with an incompressible fluid, and part of a wall of the chamber being flexible to form a diaphragm which allows external pressure from the accumulator vessel to be applied to the incompressible fluid so that the fluid is at the same pressure as the external fluids in the accumulator vessel, whereby the force transducer is arranged substantially to compensate and remove a force offset in the weight signal due to the pressure of fluids in the solids accumulator thereby allowing a fuller measurement range of the force transducer to be used and substantially dedicated to indicating a mass of solids on the weighing platform.
