Abstract: A fluid dispenser has a housing in which fluid flow control components are located and at least one fluid conduit completing first and second fluid flow paths between the at least one fluid storage tank and a nozzle coupled to the housing. The fluid dispenser also has a fluid flow meter located along said fluid flow path, a control system, and a recirculation subsystem. The recirculation subsystem has a bypass valve located along one of the first and second flow paths. The bypass valve is operative to prevent fluid communication between the first and second fluid flow paths when the fluid dispenser is in use and to allow fluid communication between the first and second fluid flow paths when the fluid dispenser is not in use. Methods of measuring the flow rate of a fluid in the fluid dispenser are also disclosed.

Abstract: A Coriolis flow meter having a first end structure, a second end structure, and a flow path extending therebetween. The first and second end structures are connectable with a conduit such that fluid flowing in the conduit enters at one of the first and second end structures, travels along the flow path, and exits at the other of the first and second end structures. The flow path has a measurement tube having first and second ends and a damper assembly. The damper assembly has at least one damper element disposed between the first end structure and the measurement tube first end. The measurement tube is not fixed with respect to the first end structure. At least one transducer is coupled with the measurement tube and is operative to sense vibration of the measurement tube and output electrical signals representative thereof.

Abstract: A fluid dispenser has a housing in which fluid flow control components are located and a fluid conduit completing a fluid flow path between a fluid storage tank and a nozzle coupled to the housing. The fluid dispenser further has a control system, at least one controllable valve and a fluid flow meter located along the fluid flow path. The fluid dispenser further has a fluid temperature conditioning subsystem located along the fluid flow path upstream of the flow meter. The control system selectively operates the fluid temperature conditioning subsystem upon detection of a predetermined temperature. At least one controllable recirculation valve may also be provided, and the control system may selectively actuate the controllable recirculation valve such that the fluid flows back to the fluid storage tank. A method of measuring the flow rate of a fluid in the fluid dispenser is also disclosed.

Abstract: A remote transaction system for contactless payment and user identification at dispensers, payment terminals, kiosks, or points-of-sale is provided. The remote transaction system comprises a compact assembly, a control system, and communications electronics. The compact assembly is adapted to be attached to a surface, such as a bezel, and comprises at least one antenna. Also, the compact assembly may comprise antennas operating at different frequencies and at least one audio or visual element. Further, antenna arrays may be formed comprising a second antenna arrangement separate from the compact assembly and coupled to the surface. The compact assembly and/or a second antenna arrangement may comprise a tuning element, such as a tuning ring. The communications electronics are adapted to wirelessly communicate with at least one remote communications device and provide wireless communications to the control system for processing. A method for attaching the compact assembly to a surface is also provided.
