1. A method of generating a desired ratio of a mixed fluid delivery system, the method comprising:
communicating a mixture of a first fluid and a second fluid to a container;
measuring a flow of the second fluid with a linear transducer and determining a volume associated with the first fluid communicated to the container and measuring a flow of the first fluid communicated to the container with a flow meter that is exposed to the flow of the first fluid;
determining a flow of the first fluid by subtracting the measured flow of the second fluid from a volume of the mixture communicated to the container; and
adjusting calibration of the flow meter associated with the first fluid flow if a comparison of the determined flow of the first fluid to a flow value detected by the flow meter is beyond a desired threshold.
