A fluid dispenser, includes: a fluid dispensation pipe, for receiving a fluid and controlling a dispensation the fluid; a MEMS sensor, for sensing a movement of the fluid dispenser, wherein when the movement is determined to be in an abnormal status, the MEMS sensor generates an alarm signal; and a dispensation stopper, for stopping the dispensation of the fluid according to the alarm signal.

A system, methods, and apparatus for preventing receptacle overfilling are presented. The system can include a sensor member configured to couple with a receptacle and sense a material level within the receptacle, such as via a sight glass of the receptacle. The system can include a controller in operable communication with the sensor member and configured to instantiate the shutoff of material flow from a material dispensing system if a particular material level is detected by the sensor member. The system can include an intermediate member configured to relay communications between the sensor member and the controller. The intermediate member can be coupled to a fluid line and can further act as a holster for the sensor member, such as by facilitating the coupling of the sensor member to the intermediate member and/or the fluid line.

Systems and methods for regulating the flow rate of fluid at a fluid dispensing nozzle. In one embodiment, a nozzle includes a body, a spout coupled with the body, and at least one fluid flow path disposed within the body. The at least one fluid flow path is configured for fluid communication with a fluid dispensing hose. An ultrasonic transducer is disposed within the body and operatively coupled with the at least one flow path. Control electronics are in electronic communication with the ultrasonic transducer. The control electronics are operative to cause the ultrasonic transducer to transmit ultrasonic waves into the at least one fluid flow path. The ultrasonic waves are modulated with information representative of a desired fluid flow rate.

A fuel dispenser system is provided including a partition part to separate a fuel dispensing unit from at least one electrically powered component. The partition part can be configured and arranged to seal the at least one electrically powered component from exposure to gas vapors emitted from the fuel dispensing unit. The fuel dispenser unit can include a fuel dispensing nozzle and a hydraulic component. The system can include additional fuel dispensing units. The fuel dispensing nozzle can be configured to dispense CNG, and the additional fuel dispensing nozzle can be configured to dispense CNG or another type of fuel. The at least one electrically powered component may include a transaction terminal.

A system and method for dispensing fluid from a reservoir cleanly using compression and negative pressure is disclosed. The system (herein referred to as System) is essentially comprised of a nozzle and a portable fluid jug (herein referred to as a reservoir). Two embodiments have a nozzle with a compression portion that when pushed against a tank neck allows fluid to flow from the reservoir. When the tank is full, fluid reaches the nozzle and blocks an internal vent line within the nozzle. This blockage builds negative pressure inside the reservoir, subsequently halting the flow of fluid through the nozzle. An object of the System is to allow fluid to flow quickly and cleanly into a fluid tank (such as those on vehicles, motor cycles, small engines, etc.) Other objects, details and embodiments of the System will be examined in further sections of this disclosure.
