Title
(EN) DUAL SENSOR VORTEX FLOWMETER
(FR) DÉBITMÈTRE À TOURBILLON À DEUX CAPTEURS
Abstract
(EN)
A vortex flowmeter includes a housing having an interior cavity, a vortex shedder supported by the housing and extending into the interior cavity, an ultrasonic sensor, a bending moment sensor and a controller. The ultrasonic sensor is configured to produce an ultrasonic flow rate output that is indicative of the flow rate of a fluid flow through the interior cavity. The bending moment sensor is configured to produce a bending moment flow rate output that is indicative of the flow rate of the fluid flow through the interior cavity. The controller is configured to generate a flow rate measurement that is indicative of the flow rate based on the ultrasonic flow rate output and/or the bending moment flow rate output.
(FR)
Le débitmètre à tourbillon comprend un boîtier présentant une cavité interne, un générateur de décollement de tourbillon soutenu par le boîtier et s'étendant dans la cavité interne, un capteur ultrasonore, un capteur de moment de flexion et un contrôleur. Le capteur ultrasonore est conçu pour produire une sortie de débit ultrasonore qui indique le débit d'un fluide dans la cavité interne. Le capteur de moment de flexion est conçu pour produire une sortie de débit de moment de flexion qui indique le débit du fluide dans la cavité interne. Le contrôleur est conçu pour générer une mesure de débit qui indique le débit sur la base de la sortie ultrasonore et/ou de la sortie de moment de flexion.
