An Air Venturi Tube consists of a tapered tube with a narrow throat section in the middle. The tube is made of a durable material that can withstand the flow conditions and pressures involved. When air flows through the venturi tube, it passes through the constricted throat section. As the flow area decreases, the velocity of the fluid increases according to the principle of continuity. Attributes:• Provide accurate and reliable flow measurements • The hose's inner diameter gradually changes from 88.9mm to 76.2mmApplications:An Air Venturi Tube measures the flow rate of air passing through it and achieves this by creating a constriction in the flow path, which causes a pressure difference between the upstream and throat sections of the tube.
