摘要
A gas flow meter uses the principle of Boyle's law to measure the gas flow rate along a path. Gas flows through a valve into a reservoir until the pressure is maximized in the volume. The valve then vents the reservoir to ambient while blocking the inlet path. The pressure at maximum and minimum values is measured by a pressure sensor and used to generate the flow rate signal. An enlarged volume in the inlet path limits the pressure rise during the exhaust phase of the measurement cycle.
