Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle behind this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the .

Engineering & Technology: Gravimetric Feeder Controls

The Gravimetric coal feeders calculates the coal flow by measuring the instantaneous weight of coal on the coal-belt.For this the load-cell output (in mV) must be correlated with a standard weight.For this purpose we subject the load-cells to a standard weight and run the empty belt.In this condition the tachogenerators are measuring the speed of the belt .Simultaneously the speed of the belt ...
