Abstract: An apparatus includes a pipe through which a multiphase fluid flows, with a transparent window structure formed in the pipe. A collimated light source emits light through the transparent window structure into the pipe having a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the pipe to impinge upon the photodetector. The photodetector has an actual dynamic range for collimated light detection. Processing circuitry is configured to continuously adjust a power of the collimated light source dependent upon an output level of the photodetector so as to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range, and determine a property of the multiphase fluid as a function of the power of the collimated light source.

Abstract: Multiphase flowmeters and related methods are disclosed herein. An example apparatus includes a flowmeter and a fluid conduit to provide a flow path for a fluid relative to the flowmeter. The example apparatus includes a sensor coupled to the fluid conduit to generate data indicative of at least one of a presence, an absence, or a mass flow rate of solids in the fluid during flow of the fluid through the fluid conduit. The example apparatus includes a processor. The sensor is to be communicatively coupled to the processor. The processor is to selectively determine flow rates for one or more phases of the fluid based on data generated by the flowmeter and a first algorithmic mode or a second algorithmic mode selected based on the sensor data.

Abstract: Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.
