Whether or not the ore density affects the accuracy of the % Solids measurement will depend on the standard deviation of the ore density and desired accuracy of the % Solids measurement.
Knowing these two values will allow an easy estimation of possible inaccuracy of the measurement due to the ore density variations. Yes, this is the limitation that any measuring device will have for the conversion of the bulk density into the % Solids.
We suggest that in the case of a significant discrepancy between the ore density value at the time of the last setup activity and the present ore density, the updated value of the ore density should be inputted into the measuring instrument. The Ultimo Density Meter is equipped with both an easy to use interactive wizard and an advanced setup GUI that allows for direct inputting of any setup parameter including the ore density.
