An automatic detection system is provided for detecting disruptions in the flow of liquid from a liquid container or containers to a dispensing apparatus. Two embodiments of the system are disclosed. In the first embodiment, a single liquid container is utilized. In the second embodiment, two liquid containers are utilized. In both embodiments, an optical sensor is employed to detect a disruption in the flow of liquid from the liquid containers to the dispensing apparatus.

A mobile fluid transfer system. The system includes a fluid evacuation system, a fluid refill system, a sensing system and a control system. The fluid evacuation system comprises a first fluid storage container. The fluid refill system comprises a second fluid storage container. The sensing system is coupled to the fluid evacuation system and the fluid refill system. The control system is coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control system is configured to determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

An automatic detection system for detecting disruptions in the flow of liquid from one more liquid containers to a dispensing apparatus. If the system detects an interruption of the flow of liquid to the dispensing apparatus, a visual alarm, an audio alarm, or a data alarm is activated. Three embodiments of the system are disclosed.

A dispensing unit is operatively associated with a refrigeration appliance for selectively dispensing water and ice at a dispensing station. The dispensing unit includes an actuator that is movable to selected positions in order to support the dispensing of the water and ice. The dispensing unit can include a passageway through which ice is dispensed, and an ice door can be provided for selectively opening and closing the passageway to the dispensing of ice. In one aspect, the ice door can be opened and closed mechanically and in another aspect, the ice door can be opened and closed electromechanically. The dispensing unit also can provide for the position of a water-dispensing nozzle to be adjusted for the purpose of dispensing water to receptacles outside a recessed area at which the nozzle is located and to provide for the activation of illuminating devices to indicate operating conditions at the refrigeration appliance.

A fuel dispenser comprises a fuel nozzle configured to be connected to a vehicle fuel system. Fuel piping configured to transfer fuel from at least one fuel storage tank associated with the fuel dispenser through the fuel nozzle into the vehicle fuel system is also provided. A flow control valve and a flow measurement device are located along the fuel piping, the flow measurement device having a housing defining a flow path therethrough. The flow measurement device includes a first exciter for producing a first wave in fuel moving along the flow path. A second exciter produces a second wave in the fuel which passes through the first wave, wherein the second wave has a higher frequency than the first wave. At least one sensor is spaced apart from the first exciter and the second exciter, the at least one sensor being configured to detect at least one measurable characteristic of the second wave from which flow rate can be derived.
