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.

Abstract: A system for identifying location of a plunger that moves along a length of a well, includes an acoustic source carried in the well configured to transmit an acoustic signal when the plunger reaches a sense location in the well. An acoustic receiver is positioned at a top of the well and is configured to receive the acoustic signal processing circuitry processes the received acoustic signal and provides an output indicative of the plunger reaching the sense location.
