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, and 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.

Surface acoustic wave (SAW) weighing apparatus and related methods are provided for measuring weight of a load employing a displaceable elastic member that is displaced by the load. A piezoelectric SAW transducer is coupled to the elastic member. The piezoelectric transducer along with an amplifier electrically coupled thereto form a delay line oscillator circuit that is configured to generate an oscillating signal in response to displacement of the elastic member by the weight of the load. A magnet is spaced from a Hall effect sensor. The magnet produces a magnetic field, and the Hall effect sensor is configured to measure strength of the magnetic field which is related to displacement of the elastic member and the weight of the load. Circuitry generates frequency data that characterizes frequency of the oscillating signal. The frequency data is related to displacement of the elastic member and the weight of the load.

An electronic measurement device or electronic scale including an arrangement of multiple low-cost sensors to measure a physical property of an object is disclosed. The electronic measurement device or electronic scale utilizes an accurate and effective calibration method that compensates for the idiosyncrasies of using individual sensors. The electronic measurement device positions a plurality of sensors at predetermined observational locations to provide sensor output signals in response to sensing physical characteristics of the physical property of the object to be measured and combines the different sensor output signals by applying a combined calibration transfer function that represents a calibration function for each of the plurality of sensors to provide a cumulative measurement signal that represents the measurement of the physical property of the object. A centroid of the mass of the object is computed and used to execute different applications.
