Title
(EN) REDUCING NOISE IN A VORTEX FLOW METER
Abstract
(EN)

A vortex flow meter is within a flow conduit. The vortex flow meter includes a housing defining a flow passage substantially in-line with the flow conduit. An actuable buff body is within the flow passage. A sensor is downstream of the actuable buff body and is attached to the housing. The sensor is configured to detect vortex shedding. A controller is configured to send a drive signal to an oscillator to oscillate the buff body. The controller is configured to receive a vortex stream from the sensor. The vortex stream is indicative of vortexes shed by the buff body within a fluid. The controller is configured to determine a flow velocity responsive to the received vortex stream.
