Method and device for dispensing liquids
First Claim
1. A method of dispensing a user-defined quantity of one or more additive liquids to a cementitious mixture comprising:
- (a) moving an additive liquid to a manifold;
(b) moving said additive liquid from said manifold to a flow meter;
(c) measuring the quantity of said additive liquid while said additive liquid is moving through said flow meter;
(d) moving said additive liquid from said flow meter to a cementitious mixture;
(e) optionally, repeating (a)-(d) for one or more additional additive liquids;
(f) purging at least one of said manifold and said flow meter with a purgative fluid, wherein at least a portion of said purgative fluid is moved to a cementitious mixture;
wherein there is substantially no accumulation of additive liquid in the manifold or any components downstream of said manifold.

Abstract
Disclosed is a method and apparatus for dispensing a user-defined quantity of one or more liquids for use in a cementitious mixture. The method includes moving a liquid from a liquid supply to a manifold; moving the liquid from the manifold to a flow meter; measuring the liquid while it moves through the flow meter; moving the liquid to a cementitious mixture; repeating these steps for any additional liquids; flushing any remaining liquid from the manifold with a purgative fluid; and moving purgative fluid and flushed liquid to the cementitious mixture.

21. A device for dispensing liquids comprising:
-
an additive liquid supply; a purgative liquid supply; a manifold comprising a plurality of inputs, a flow path in fluid communication with each of said plurality of inputs, and an output in fluid communication with each of said flow paths, wherein output is substantially equidistant from each of said plurality of inputs and wherein said flow paths comprise a substantially same volume; and a flow meter in fluid communication with said manifold capable of measuring the quantity of said additive liquid while said additive liquid is moving through said flow meter.
