Abstract
A mass flow meter includes a flow pathway through the mass flow meter, wherein the flow pathway comprises a first cavity and a second cavity. The mass flow meter also includes a laminar flow element adjacent to the first cavity and the second cavity, wherein the first cavity is upstream of the laminar flow element and the second cavity is downstream of the laminar flow element. A pressure transducer is positioned in at least one of the first cavity or the second cavity, wherein the pressure transducer includes at least one diaphragm and measures linear and non-linear responses of the at least one diaphragm to a first pressure to determine a voltage signal indicative of a pressure. The mass flow meter converts the pressure reading obtained from the pressure transducer into a signal indicative of a mass flow rate through the laminar flow element.
