Liquid blending and dispensing apparatus |
摘要 |
Liquid dispensing apparatus for dispensing a blend of first and second liquids has flowmeters operable to measure the quantity of each liquid delivered. The flowmeter outputs are multiplied by a factor equal to the proportion of one liquid in the blend and used to control a stepping motor which operates a blending valve. An error correction circuit is provided to correct for any accumulated error, and the apparatus also includes a cost determining circuit.
