ABSTRACT:
Methods and systems for determining the identity and flow rate of a fluid are provided. Linearized output signals are provided. To determine fluid flow, a test fluid is passed through a conduit. A heater associated with the conduit is maintained a temperature greater than the temperature of the conduit in the presence of the test fluid. A measuring voltage is generated, wherein the measuring voltage is indicative of the voltage required to maintain the heater at the specified temperature. A data set is provided to a computer, which compares the measuring voltage with a reference voltage and determines the identity of the test fluid. Further, a flow function is applied to the data set and the fluid flow rate is calculated.
