In some embodiments, an electronic fuel management control and accounting system may include: a server having a management logic in a memory and executable by a processor; a client device having an interface logic in a memory and executable by a processor; and a dispenser control device communicatively coupled to a material providing system to control dispensing of a material from the material providing system. A dispensing logic may be stored in a memory of the dispenser control device and executable by a processor of the dispenser control device. The dispensing logic may communicate with the management logic of the server via the interface logic of the client device thereby allowing the management logic to control dispensing of the material from the material providing system. The system may enable any number of client devices, such as cell phones, to instantly provide access to the material providing system.

In one embodiment, a liquid dispenser includes a liquid reservoir, a measurement device providing at least one signal indicative of the amount of liquid remaining in the liquid reservoir, an electrically actuated valve coupled to a tube outlet exiting from a bottom of the liquid reservoir, and a processor. The processor is electrically connected to the measurement device and operatively coupled to and controlling operation of the valve. Further, the processor is configured to determine a valve open time for dispensing a requested amount of liquid. The valve open time depends upon a preliminary time based on the requested amount and at least one signal from the measurement device, and an adjustment to the preliminary time based on a difference between a requested amount and a measured amount determined by the measurement device for at least one previous dispense.

A liquid supply system is provided. The liquid supply system includes a liquid tank configured to store a liquid. The liquid supply system also includes a liquid measurement module positioned outside the liquid tank and fluidly connected two connecting ports that are located at opposite sides of a surface of the liquid stored in the liquid tank, The liquid tank includes a tube extends parallel to a height direction of the liquid tank. The liquid tank also includes a floating member located in the tube and configured to float on the liquid. The liquid tank further includes a detection member configured to emit a detection signal toward the floating member.

Food blending can include maintaining a reservoir for holding a liquid for use in blending a set of food ingredients; and dispensing the liquid from the reservoir into a container for blending the food ingredients in the food blending system.
