    摘要: A vortex flowmeter has first and second process connections with a meter inlet and outlet, respectively, therein. The first and second process connections are configured to connect, respectively, to upstream and downstream segments of a fluid pipeline. A fluid conveyance system conveys fluid from the inlet to the outlet and divides the fluid into separate fluid streams that flow through separate passages. Each of the passages has its own vortex metering unit configured to generate and detect vortices in the respective fluid stream. A processing system is configured to calculate a sum of the flow rates through all of the fluid streams.

    摘要: A vortex flow meter that senses the alternating pressure variations generated by a fixed vortex shedding generator. The alternating pressure variations of the vortices within the rows on each side of the vortex shedding generator act upon flexible elements producing forces on long columns that are transmitted to remotely located piezoelectric force sensors. The alternating forces upon the two columns are used to determine the passage of a vortex and thereby the flow. Improved output signal by minimizing loss of parasitic energy. 97% of the available signal is applied to the piezoelectric force sensors as compared to conventional 60%. Process influences such as vibration in all planes and pumping pulsations are equal and opposing and are rejected by the sensor. A capability of operating at extreme process temperatures is assured for the high temperature of the process is dissipated to the environment along the long columns. Reliability of operation is assured for the sensor has no process seals and is easily replaced by technicians, without interrupting flow or venting process. Improved process containment is realized with construction having a high safety factor and multiple stages of process containment. Wafer form reduces installation costs and an optional redundant sensor improves reliability of operation, decreases pumping losses, and only requires one K-factor. Process up-time is assured with an economical redundant sensor.

    摘要: A flowmeter having a vortex type detection means with a measurement tube provided in a flow passage that allows passage of a fluid therethrough, and having a vortex generator provided in the measurement tube that is opposed to a flow of the fluid. The flowmeter also includes a vortex detector detecting a change based on a Karman vortex generated by the vortex generator, a thermal type detection means having a temperature sensor and a heating temperature sensor protruding into the flow passage, and a flow rate converter controlling a power supply amount related to heating of the heating temperature sensor for attaining a fixed difference in temperature between the temperature sensor and the heating temperature sensor and calculating a flow rate of the fluid from the power amount. The flow rate converter also calculates the flow rate of the fluid from a detection value obtained by the vortex detector.

    摘要: A flowmeter having no moving parts and including a vortex shedder mounted transversely in a conduit forming a passage for the fluid being measured. The shedder is provided with an axially-extending gap perpendicular to the direction of fluid flow in the conduit, and means to establish a magnetic field in the gap whose lines of flux are parallel to the direction of flow. Fluid oscillations produced in the gap as a result of Karman vortices are detected on the induction principle by a pair of electrodes mounted on said shedder at axially-spaced positions within said gap. The frequency of the signal developed at the electrodes is proportional to the flow rate or flow velocity and is undisturbed by common mode flow noise.
