Patent ID: 8201457

Claim:
A fluid measuring device comprising: a. a hollow body for receiving and emitting a fluid, the hollow body comprising: (i) an exterior surface, an interior surface, and a chamber with a first diameter within the hollow body; (ii) a first beveled surface at a first end of the hollow body configured to connect inline with an upstream conduit; and (iii) a second beveled surface at a second end of the hollow body configured to connect inline with a downstream conduit; b. a conical section mount and a support member in the hollow body, wherein the conical section mount is concentrically disposed within the hollow body, and wherein the conical section mount comprises mounting surfaces; c. a sensor mount flush on the exterior surface comprising: (i) an upstream pressure port extending into the chamber proximate the first end of the hollow body; (ii) a downstream pressure port extending into the support member downstream from the upstream pressure port; (iii) a temperature port extending into the support member for sensing a temperature of the support member representing a temperature of the fluid at the conical section mount; and (iv) a downstream diagnostic port extending into the chamber proximate the second end of the hollow body; d. a detachable and re-attachable conical area ratio changer connected to the mounting surfaces of the conical mount section, wherein the detachable and re-attachable conical area ratio changer comprises a central bore; e. a bore in the conical section mount and in communication with the downstream pressure port; and f. a hollow fastener disposed through the central bore and the bore, wherein the hollow fastener is configured to align and center the detachable and re-attachable conical area ratio changer to the conical section mount and the support member.
