Abstract: Methods and systems for intermittently mixing a fluid in a tank based on information received from at least two data acquisition devices that are vertically spaced on the tank and capable of obtaining at least one property or characteristic of the fluid that is in the tank and adjacent to each data acquisition device. A data analyzer compares data measurements received from the data acquisition devices and intermittently operates a mixer to maintain homogeneity of at least one chemical characteristic or physical property of the fluid both prior to and during dispensing of the fluid from the tank. The method further utilizes information received from the at least two data acquisition devices to assist in calculating a volume of fluid dispensed from the tank.

Abstract: A method is taught for maintaining a fluid within a tank. In this method an upper data acquisition device is operated which is capable of obtaining at least one characteristic of the fluid in a tank adjacent to the upper data acquisition device. A lower data acquisition device is also operated which is situated below the upper data acquisition device, capable of obtaining at least one characteristic of the fluid in the tank adjacent to the lower data acquisition device. A data analyzer is then utilized which is capable transmitting a data packet to the intermittent mixer. The method then automatically turns on the intermittent mixer from the data received from the data packet. Afterwards, the method automatically turns off the intermittent mixer from the data received from the data packet resulting in the at least one characteristic from the upper data acquisition device is within specifications of the at least one characteristic from the lower data acquisition device.

Abstract: In one embodiment, the present system describes a system wherein a first fluid is within a tank. An intermittent mixer is used for agitating the first fluid within the tank. At least one data acquisition device within the tank is capable of measuring at least one characteristic within the first fluid. In the embodiment, at least one data analyzer is capable of receiving the characteristics within the first fluid, comparing the characteristics within the first fluid to the characteristics of a second fluid, generating a data packet which contains a calculated operational speed and an operational time needed for the intermittent mixer to agitate the first fluid to obtain the characteristics of the second fluid and transmitting the data packet to the intermittent mixer. In this system the intermittent mixer is capable of altering the first fluid within the tank into the second fluid.
