摘要： Disclosed are systems and methods for measuring flowrates. The systems and methods may include passing a fluid from a unit under test into a cavity. The pressure of the fluid within the cavity may be measure and a slidable element located within the cavity may be repositioned to maintain a desired pressure within the cavity. The distance traveled by the slidable element in order to maintain the desired pressure may be determined along with a time for the slidable element to travel the distance. Using the distance traveled by the slidable element, a crosssectional area of the slidable element in contact with the fluid, and the time for the slidable element to travel the distance the volumetric flowrate for the fluid may be determined.

摘要： An apparatus and method for use in determining one or more fluid flow properties of a fluid in a conduit is disclosed. The apparatus includes a substrate including a barrier, a first flow sensor coupled to the substrate and a second flow sensor coupled to the substrate. The first flow sensor is located at a first sensor distance from a first barrier surface, and the second flow sensor is located a second sensor distance from the second barrier surface. The first sensor distance is substantially equal to the second sensor distance. In operation, the first flow sensor produces a first sensor signal, and the second flow sensor produces a second sensor signal. The direction of flow for the fluid is determined by comparing the first sensor signal to the second sensor signal.
