Abstract
An apparatus for assisting with measurement of a fluid pressure includes a cover layer having a leading cover edge and upper and lower cover surfaces. A cover aperture fluidly connects the upper and lower cover surfaces. A spacer layer has oppositely facing upper and lower spacer surfaces. A cavity has an upper cavity surface, defined by the lower cover surface, which includes the leading cover edge and the cover aperture. A measuring tube is located adjacent to the upper cover surface. The measuring tube includes a tube lumen. When the lower spacer surface is connected to the substrate, the substrate defines a lower cavity surface and extant fluid is present within the cavity. Variable fluid flowing toward the cavity exerts pressure on the extant fluid to generate an extant fluid pressure level which is physically transmitted through the apparatus and made available for measurement as an extant fluid pressure level.
