Abstract

The present disclosure provides thermal gas property sensors and compensated differential pressure sensors, as well as methods for measuring a physical property of a gas and methods for compensating differential pressure sensors. A reference overpressure of a gas is generated in a cavity. Based on the flow of the gas from the cavity through a channel, properties of the gas are identified.
