Abstract: In one embodiment, a method for delivering a gas at a predetermined rate includes providing a gas flow control apparatus comprising a gas flow path extending from a gas inlet to a gas outlet, a proportional valve coupled to the gas flow path, an on/off valve coupled to the gas flow path, a volume being defined between the proportional valve and the on/off valve, and a flow restrictor having a flow impedance located downstream of the proportional valve. The volume is pressurized with the gas to a target set point by opening the proportional valve while the on/off valve is in an off state. Finally, the on/off valve is moved to the on state, delivering gas to the gas outlet.

Abstract: The LFFC technology allows for accurate measurement and metering of fluids in a HVAC system-based on parameters such as pressure, velocity, volume, particles, and temperature. A procedure in a processor allows for the calibration of the aperture devices thru various methods in real time based on the actual system performance. The fluid aperture device calibration curves can be developed in a lab environment, on calibrated flow stands and/or field calibration methods using adaptive learning software based on sensor data. The procedure can rely on calibration curves, characterizations, equations, predictive analysis, machine learning, artificial intelligence, simulation software, calibrated flow stands, duplicating environmental conditions, various sensor data and programming software executed by a processor or system software. Upstream and downstream reference points for temperature, flow, particles, and pressure can be used as additional data to auto calibrate/commission the system thru the software.

Abstract: A method can include calibrating a model using pressure and flow rate data to generate a calibrated model; receiving an upstream pressure value and a downstream pressure value that define a pressure differential across a flow device; and computing a flow rate through the flow device using the upstream pressure value, the downstream pressure value and the calibrated model.
