Abstract
First and second elongated conduits each have an inlet and an outlet. First and second resistive elements having a resistance related to their temperature are disposed in the first and second conduits, respectively, in heat transfer relationship with gas flowing therethrough. A mixture of a first gas and a second gas having a different thermal conductivity than the first gas is supplied to the inlet of the first conduit in a fixed ratio. A mixture of the first and second gases is supplied to the inlet of the second conduit in a variable ratio related to a variable pressure to which a branch of a T-network is exposed. The sensor is specifically employed as a flowmeter, a micrometer, or a pressure sensor.
