Abstract
An electronic flow meter that is configured to use localized flow conditions to determine volumetric flow. The embodiments may include a body forming a pass-through channel and a by-pass channel; a semiconductor device comprising a sensor disposed proximate the by-pass channel, the sensor configured to generate a signal with data that reflects localized pressure and localized temperature of a stream in the by-pass channel; and a processing component coupled with the sensor to receive and process the signal so as to identify a flow condition for the stream, select a calculation for volumetric flow rate in response to the flow condition, use data for localized pressure and localized temperature in the calculation to generate a value for the volumetric flow rate; and generate an output with data that reflects the value for the volumetric flow rate.
