Abstract: A sensor probe comprises a tube, a sensor element and an absorber mass. The tube is for placement in a process fluid flow within a fluid conduit and comprises a first end for coupling to the fluid conduit and a second end for insertion into the process fluid flow. The sensor element is in communication with the tube. The absorber mass is coupled to the tube and is configured to dampen vibration of the tube when inserted in the process fluid flow.

Abstract: A process variable transmitter is configured as a flowmeter for measuring flow of a process fluid through a conduit. The transmitter includes 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 is mounted on the pitot tube and coupled to the flow of process fluid to sense an upstream process variable of the process fluid. A downstream process variable sensor is mounted on the pitot tube downstream of the upstream process variable sensor and coupled to the flow of process fluid to sense a downstream process variable of the process fluid. Measurement circuitry determines the flow of the process fluid based upon the upstream process variable and the downstream process variable.
