Title (EN) VORTEX FLOWMETER HAVING INJECTION CLEANING PORTS
(FR) DÉBITMÈTRE À VORTEX AYANT DES ORIFICES DE NETTOYAGE PAR INJECTION
Abstract:
(EN) A vortex flowmeter for measuring a flow rate of a fluid has a flowtube and a bluff body positioned in the flowtube for shedding vortices in the fluid when the fluid flows through the flowtube. A sensor is positioned to detect the vortices. A cleaning port is positioned to allow a stream of fluid to be directed into the flowtube through the cleaning port toward the sensor for cleaning material away from the sensor. A method of cleaning the vortex flowmeter includes injecting a fluid into the vortex flowmeter toward the sensor through the cleaning port.
(FR) Débitmètre à vortex destiné à mesurer un débit d'un fluide comportant un tube d'écoulement et un corps non profilé positionné dans le tube d'écoulement pour éliminer les vortex dans le fluide lorsque le fluide s'écoule dans le tube d'écoulement. Un capteur est positionné pour détecter les vortex. Un orifice de nettoyage est positionné pour permettre à un flux de fluide d'être dirigé dans le tube d'écoulement par l'orifice de nettoyage vers le capteur pour nettoyer le matériau à l'opposé du capteur. Un procédé de nettoyage du débitmètre à vortex consiste à injecter un fluide dans le débitmètre à vortex vers le capteur par l'orifice de nettoyage.
