“…2b . In addition, our PC based system can work across a wide range of water-cuts and potentially detect three-phase flow with a single set of measurements, without the limitations, such as specific fluid conditions, composition, and operational modes required by other intrusive methods 15 , 37 – 40 .…”

“…Multiphase flow measurements (MPFM) consist of a collection of technologies to infer flow characteristics such as, phase fractions 14 – 18 , flow rates 19 – 22 , and flow morphology. Conventional techniques to determine these flow characteristics are cumbersome to implement, prone to fouling and error, and require regular calibration 15 . This includes microwave-based phase fraction measurements which either do not sample the entire flow cross-section, or require a support structure or an alternative low-frequency RF band to allow for energy transmission through fluid mixtures with a high water cut 15 .…”

Multiphase flows are ubiquitous in industrial settings. It is often necessary to characterize these fluid mixtures in support of process optimization. Unfortunately, existing commercial technologies often fail to provide frequent, accurate, and cost-efficient data necessary to enable process optimization. Here we show a new physics-based concept and testing with lab and field prototypes leveraging photonic crystals for real-time characterization of multiphase flows. In particular, low power (~1 mW) microwave transmission through photonic crystals filled with fluid mixtures may be interrogated by deep learning analysis techniques to provide a fast and accurate characterization of phase fraction and flow morphology. Moreover when these flow characteristics are known, the flow rate is accurately inferred from the differential pressure necessary for the flow to pass through the photonic crystal. This insight provides a basis to develop a unique class of inexpensive, accurate, and convenient techniques to characterize multiphase flows.

“…Accurate flow metering of complex fluids is a critical need in many industries, with a spectrum of applications ranging from quality control in foods, cosmetics, and pharmaceuticals to field optimization in petroleum production [1][2][3][4][5]. Systems such as these are inherently multi-phase, and can comprise many combinations of gas phases, multiple solid phases and multiple liquid phases.…”

We present techniques to measure fluid flow rates in single- and multi-phase fluid flows by detecting the motion of injected tracers. Our methods exploit acoustic impedance differences between liquids and gases to allow one to sense the presence of micron-sized gas bubbles in a liquid when it is irradiated with ultrasonic energy. By cross-correlating signals at multiple locations along the path of flow, the velocity of the moving fluid can be accurately estimated. We report experimental results in single- and two-phase fluid flows and describe the methodologies used in each case that are necessary to enable accurate measurements. In cases of single- and two- phase flows, respectively, flow rates can be measured to less than 5% and less than 10%–15% of known flow rates. While our experiments leveraged differences in acoustic properties, the methods may be generalized to other means of measurement.

“…One of the common limitations is that they are flow regime dependent and can only work on one flow regime. Others are intrusive, disturb the flow pattern and create an unwanted pressure drop in the system [7]. Non-invasive measurement techniques such as gamma densitometry will obviously not disturb the flow pattern or create a pressure drop.…”
