Using localized flow characteristics on electronic flow meter to quantify volumetric flow

An apparatus, comprising:

• a body having a pass-through channel forming a main fluid stream and at least one by-pass channel coupled with the pass-through channel;
• a semiconductor device comprising a sensor disposed proximate the at least one by-pass channel, the sensor configured to generate data that reflects measured conditions comprising at least one value for pressure and at least one value for temperature of a portion of the main fluid stream in the at least one by-pass channel;
• and
• a processing component coupled with the sensor to receive the data, the processing component comprising a processor, memory coupled with the processor, and executable instructions stored on the memory and accessible by the processor, the executable instructions comprising instructions that, when executed by the processor, configure the processor for:
• using one or both of amplitude characteristics of the data and temporal characteristics of the data to identify a flow regime for the main fluid stream and flow parameters thereof;
• selecting a process to determine a volumetric flow rate of the main stream in response to the flow regime;
• using data for the at least one value for pressure and the at least one value for temperature in the process to generate a value that defines the volumetric flow rate of the main stream;
• and
• generating an output with data that reflects the value for a reported volumetric flow rate of the main stream.
