What is vortex flow. In this flow vortices are created at the back of the body and detach periodically from either side of the body. Vortex flow meters use the von karman effect to measure the rate of flow of a fluid or gas. Universal flow monitors inc. Welcome to vortek instuments llc turbine flow meters vortex flow meters turbine flowmeters vortex flowmeters.
Vortices form in stirred fluids and may be observed in smoke rings whirlpools in the wake of a boat and the winds surrounding a tropical cyclone tornado or dust devil. In fluid dynamics a vortex plural vorticesvortexes is a region in a fluid in which the flow revolves around an axis line which may be straight or curved. The rosemount 8800d series vortex flow meter is available in wafer flanged reducer flange dual sensor and high pressure designs. The whole assembly can then be inverted and the process repeated.
The vortex panel method is a method for computing ideal flows flows in which the effects of compressibility and viscosity are negligible. The vortex panel method applet is a computational tool for students studying the aerodynamics of airfoil sections. In fluid dynamics vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff as opposed to streamlined body at certain velocities depending on the size and shape of the body. Vortices are a major component of turbulent flow.
A vortex flow meter is a flow measurement device best suited for flow measurements where the introduction of moving parts presents problems. Early in the 20th century a hungarian american mathematician and physicist theodore von karman discovered that a fluid or gas flowing perpendicularly pass a bluff body would generate alternating vortices on both sides of. Learn about types of vortex flow meters how they work. Vortek instruments manufactures precision multivariable flowmeters such as turbine flow meters vortex flow meters for the measurement of liquid gas and steam in commercial industrial and municipal applications for the water and waste water chemical petrochemical oil gas.
Manufactures vane style vortex shedding rotameters and laminar flow element flowmeters for use in industry. What is the von karman effect. Applications of special interest are circulating lubrication fluid cooling water industrial gas corrosives and brine. Vortex flow meters measure fluid velocity using a principle of operation referred to as the von karman effect which states that when flow passes by a bluff body a repeating pattern of swirling vortices is generated.
The all welded non clog design on the rosemount 8800d series vortex flow meter eliminates impulse lines ports and gaskets which improve reliability.
