Abstract
The improved automatic dampening water replenisher has two flow sensors that respectively measure the flow rates of stock solution and diluent water which are to be mixed to prepare dampening water with which the tank of dampening water is to be replenished, and this enables the concentration of dampening water in its tank to be maintained within a predetermined range at all times. If desired, the apparatus (the replenisher) may be equipped either with components for computing, displaying and storing the total flows of stock solution and diluent water or with an emergency alarm generator which issues an alarm indicating the occurrence of aberrations in the concentration of dampening water in its tank. This offers the advantage that normal operation of the apparatus can be resumed as soon as power failure is remedied, or the suspension of water supply and other troubles can be readily identified and corrected to avoid unwanted variations in the concentration of the dampening water.
