    摘要: A test apparatus (100) to test operation of a gas meter (108). The test apparatus (100) may include metrology devices, namely, a master meter (110) and a measuring device (112), typically with a sensor to measure ambient conditions that prevail at the master meter (110) and the gas meter (108). Each of the metrology devices (110, 112) can be configured as a self-contained, independent unit that can process analog signals to generate a digital signal (114). A controller (128) may process these digital signals (114) to convey information that defines flow volume for gas (122) that flows through the gas meter (108). The controller (128) may also be configured to verify a regulatory status for the metrology devices (110, 112). These configurations can use validation data stored on the metrology devices (110, 112) separate and independent of the controller (128). In this way, the test apparatus (100) assumes a modular structure that allows the metrology devices (110, 112) to swap into and out of the test apparatus (100).

    摘要: A locking mechanism for a stop flange is provided with a screw having a head with at least one circumferential channel, and a screw gasket disposed on the at least one circumferential channel. A bushing receives the head in a cavity that forms a housing for the head and screw gasket. The bushing may be provided with a lip that engages a shoulder on a radial bore in a stop flange.

    摘要: Embodiments of devices and methods distribute power in a remote pumping system to avoid charge imbalances in energy storage devices of an array. These embodiments identify certain energy storage devices in the array in which the output voltage is less than or equal to a threshold value. In one example, power from a plurality of power sources is directed to the non-performing energy storage devices to expedite recharging of these energy storage devices.

    摘要: Embodiments of a system and method manipulate the position of inlet guide vanes and the drive speed for optimizing performance of a compressor device (e.g., a centrifugal compressor). In one embodiment, the systems and methods can correlate setpoints (e.g., inlet volume flow and discharge pressure) desired for installation and/or implementation of the compressor device with reference data collected as part of in-situ performance testing. This reference data identifies, in one embodiment, a position for the inlet guide vanes and a drive speed for a number of different setpoints at a set of reference conditions (e.g., ambient temperature and ambient pressure).

    摘要: Embodiments of a diffuser assembly incorporate a diffuser vane with a trailing edge that changes position to improve flow performance of a compressor device. In one embodiment, the trailing edge rotates about the leading edge. This configuration maintains the position of the leading edge on the diffuser vanes relative to the orientation of the working fluid.
