Abstract: A displacement pump has multiple gas compression stages and serial gas flow through the compression stages. The gas is initially compressed in a first compression stage by a first fluid displacement member. The gas from the first compression stage flows to a second compression stage. The gas in the second compression stage is compressed by a second fluid displacement member and output from the pump.

Abstract: An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacement member to drive axial reciprocation of the fluid displacement member. A drive mechanism is disposed between and connected to each of the rotor and the fluid displacement member. The drive mechanism receives a rotational output from the rotor and provides a linear input to the fluid displacement member. A controller controls operation of the motor based on an operating state of the motor to control pumping by the displacement pump.

Abstract: A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

Abstract: A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

Abstract: A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.
