• providing a computer electronically coupled with the first probe, the electrical pulse emitter, the electrical pulse sampler, and the database, and wherein the computer determines a time period between the electrical pulse emission into the first probe, and the receipt of the sensed electrical pulse reflection from the first probe, and wherein a resonance point of the volume fraction constituent is calculated by the computer from the determined time period by applying a Fast Fourier Transform to the determined time period, and wherein the computer further correlates the determined time period to the previously determined and known dielectric constant and to the previously determined and known resonance points of the volume fraction constituent as provided in the database to identify the volume fraction constituent in the fluid;
• providing a computer electronically coupled with the second probe, the electrical pulse emitter, the electrical pulse sampler, and the database, and wherein the computer determines a time period between the electrical pulse emission into the second probe, and the receipt of the sensed electrical pulse reflection from the second probe and wherein a resonance point of the volume fraction constituent is calculated by the computer from the determined time period by applying a Fast Fourier Transform to the determined time period, and wherein the computer further correlates the determined time period to the previously determined and known dielectric constant and to the previously determined and known resonance point of the volume fraction constituent as provided in the database so as to identify the volume fraction constituent in the fluid;
• generating a first output from the first probe when a volume fraction constituent is sensed by the first probe and generating a second output from the second probe when the same volume fraction constituent is sensed by the second probe, and communicating the first and second probe outputs to the computer;
• determining the volume of the volume fraction constituent sensed by the first probe by determining a velocity of the volume fraction constituent moving through the pipe by calculating a time difference between the first probe output and the second probe output and correlating the calculated time with the known total volume of fluid flowing through the pipe;
