Abstract: Disclosed is a system and method for ultrasonic measurement of the average diameter and roundness profile of a tube. A roundness algorithm represents the angular dependence of the tube surface profile as a sum of Fourier components, each component being a harmonic representing an integer number of undulations per revolution, with “0” (the first harmonic) corresponds to an average circle associated with the tube outer surface. A calibration block is used to calibrate the first harmonic, representing the average tube diameter.

Abstract: An ultrasonic transceiver array provides for measurement and determination of flow rate of oil, water and gas in a multiphase flow in a pipe or conduit. The transceiver array is mounted externally and non-invasively in an elliptical arrangement on the pipe surface, resulting in an ellipsoid section of the flow cross-sectional area to be interrogated. The single ultrasonic transceiver array forms a tomographic image of multiphase flow to determine volume fraction of each phase; measure the total flow velocity to determine flow rate of individual phases and thus provide a three phase measurement capability. Both phase fractions and flow velocities can be determined at the same time, eliminating the need for two different systems to achieve that purpose.

Abstract: A testing platform tests an electrical and mechanical system such as an HVAC unit according to an algorithm that reduces the total testing time of the components of the system, while ensuring the safety of the system during system-wide testing. The platform uses constraints that are checked both before and during the testing to ensure that HVAC operating conditions are acceptable for starting and maintaining component tests. Preferably, the platform uses finite-state machines for each device to organize the component tests, allowing for monitoring of constraints and starting, pausing, and stopping component tests. Preferably, total test execution time is reduced by running component tests in parallel, running component tests based on loads of the components, or combinations of both.
