Abstract: The present invention provides a fluid measurement apparatus, including a pressure sensing element and a data processing element. The pressure sensing element is disposed in direct contact with a measured fluid, the pressure sensing element is a sealed element, and includes a first surface and a second surface that are disposed opposite to each other, the measured fluid directly impacts the first surface and the second surface, and pressure values generated when the first surface and the second surface are impacted by the measured fluid are detected. The data processing element is connected to the pressure sensing element, and a flow velocity and/or a flow rate of the measured fluid are/is calculated by using the pressure value detected by the pressure sensing element. The present invention resolves a problem that the fluid measurement apparatus cannot operate normally due to clogging of a pressure tap hole.
