ABSTRACT:
A method and apparatus for determining selected fluid properties including thermal conductivity, pressure and/or temperature using a single heater element of the sensor, and in a relatively short period of time. This is accomplished by measuring a variable phase or time lag between an input signal provided to the heater element and a subsequent transient temperature response of the heater element.
