  • Publication number: 20250137825
    Abstract: A flow conditioning assembly for a flow velocity and mass flow measurement apparatus utilizing micromachined flow sensing elements is disclosed for maintaining high metrological performance. The assembly introduces a flow profile shatter and redistribution mechanism before the flowing fluid enters the flow straightener and flow profiler combined flow conditioning. The assembly further removes the probability of flow clogging, has a low flow resistance, and relaxes the metrological requirements of the connecting pipework system. An alternative build with a bypass flow chamber with a flow redistribution channel allows the measurable flow velocity to extend to more than three times the configuration where the micromachined flow sensing elements are placed inside the center of the main flow channel.
