A method for controlling a rotary tablet press comprises the steps of consecutively supplying material into each die of a die table, subjecting the material to a pre-compression and a main-compression, measuring, during the pre-compression, a value representative of the weight of material compressed, and during the main-compression, a value representative of the hardness of the resulting tablet. The quantity of material supplied to each die is regulated on the basis of a deviation between a measured value representative of the weight and a first set value. The degree of compression during main-compression is regulated on the basis of a deviation between a measured value representative of the hardness and a second set value.

An apparatus for determining total hardness in a fluid stream utilizing an ion exchange column in a monovalent cationic form having an inlet and an outlet, where one or more monovalent ion selective electrodes are positioned either at an inlet, outlet, or at both locations simultaneously. The monovalent cation selective electrodes are in electrical communication with one another, and in fluid communication with one or more valves incorporated within a fluid path in order to introduce feed water/softened water to the monovalent cation selective electrodes. Additionally, one blending valve may be incorporated in the ion exchange column to allow a fraction of the feed (hard) water to mix with a fraction of the softened water. In this manner, the blending valve may be utilized to adjust the hardness of the water at the output.
