ABSTRACT:
The present invention relates to a method for determining the level of concrete in a concrete mixer comprising the steps of contacting the exterior of concrete mixing drum with a strip of thermal color sensitive material and observing the interface on the color sensitive material produced by the temperature differential between the concrete and the air above. This level can then be lined up horizontally with a graduated volume indicator, to yield the concrete volume in the truck to aid in determining an effective amount of additive to be added to the concrete.
