A throttling component and a conditioning and flowrate measurement device including a throttling component. The throttling component comprises a central throttling element and multiple peripheral throttling elements. The multiple peripheral throttling elements are sequentially sleeved on the exterior of the central throttling element, and are coaxial to the central throttling element; annular fluid channels are respectively formed between the central throttling element and its adjacent peripheral throttling element, and between adjacent peripheral throttling elements. A sensitive and clear differential pressure signal is generated while the throttling component stabilizes the flow, so that the accuracy and reliability of flowrate measurement can be improved.

The insertable flow meter assembly also includes an end cap configured to engage an exterior surface of the receiving structure and to couple to the receiving structure at an end of the flow passage. The end cap is configured to block movement of the flow measuring device out of the end of the flow passage.

New and/or alternative approaches to determine mass flow using a flow measurement device in a pulsatile flow context. The flow measurement device is configured to generate a delta-pressure measurement. A semi-physical valve model is generated for the flow measurement device, and the delta-pressure measurement is then is isolated using the model. A discharge coefficient map is determined for the flow measurement device by testing using sets of operating parameters for a system. The operating parameters of the system are then used to determine the discharge coefficient for use in estimating mass flow with the semi-physical valve model. The resultant estimated mass flow can be used to control the system, and a Factor of Effective Area estimate generated using the valve model can be used to determine the status of the flow measurement device and identify or predict a need for maintenance.
