Claim:
1. A flowmeter for measuring flow of a process fluid through a conduit, comprising: a pitot tube extending into the conduit which creates a differential pressure in the process fluid due to flow of the process fluid; an upstream process variable sensor mounted on the pitot tube and exposed to a pressure generated by the flow of process fluid configured to sense an upstream process variable of the process fluid and responsively provide a first output; a downstream process variable sensor mounted downstream of the upstream process variable sensor mounted on the pitot tube and exposed to a pressure generated by the flow of process fluid configured to sense a downstream process variable of the process fluid and responsively provide a second output; and a measurement circuitry configured to determine the flow of the process fluid based upon the first output from the upstream process variable sensor and the second output from the downstream process variable sensor; wherein the upstream and downstream process variable sensors comprise a brittle material having a cavity formed therein which deforms in response to applied pressure.
