<p>Apparatus and method for accurate measuring and mixing of chemicals is disclosed. The apparatus includes one or more metered vessels (12) having a container (42) of predetermined volume and at least one constricted vent tube (44) therein. By mounting a sensor (54) on the constricted vent tube, a greatly amplified measurement of the precise chemical volume in the metered vessel is provided. The apparatus and method of the present invention readily lends itself to a variety of applications and can be adapted to handle virtually any form of chemical mixing, diluting, or generating process.</p> |
