    摘要: Systems and methods for flow verification and validation of mass flow controllers are disclosed. A mass flow controller may be commanded to a specified flow and flow measurement commenced. During an interval, gas is accumulated in a first volume and measurements taken within this volume. The various measurements taken during the interval may then be used to calculate the flow rate. The flow rate, in turn, may be used to determine the accuracy of the mass flow controller relative to a setpoint.

    摘要: A burner for a conventional gas burning barbecue of the type having a pair of gas feed valves. The burner comprises a pair of gas burner tubes, a portion of each of which is rectangularly configured. The rectangularly configured portion of one of the burner tubes is centrally positioned within the rectangularly configured portion of the other. Each of the burner tubes has an air/gas inlet tube, communicating with its rectangular portion, which is positioned to receive a gas outlet tube from a different gas feed valve of the barcecue so as to enable independent control of the gas flowing to each rectangularly configured portion.
