PRECISION VOLUMETRIC MEASURING AND MIXING APPARATUS |
摘要 |
<p>An apparatus for mixing a first liquid with at least a second liquid includes a tank having a mixing chamber to which is connected a first and a second supply line from each of a first and a second source of liquid. A gross control valve disposed in each of the first supply lines and a fine control valve disposed in each of the second supply lines. A noncontacting detector measures the total volume of liquid present in the mixing chamber. A controller, operable in response to signals output from the detector representative of the total volume within the mixing chamber as continuously measured by the detector, actuates in accordance with a predetermined sequence the gross and the fine control valves in the respective first and second supply lines from the first source and from the second source in accordance with a predetermined sequence.</p> |
