The design concept of this sensor is shown in fig.
Vortex Shedding Flow Meter. Increasing flow increases the frequency of oscillation. The microprocessor in the flowmeter can automatically correct for.
Learn The Truth About Vortex Shedding Flow Meter | Sino-Inst from www.drurylandetheatre.com
Vortex meters measure flow by detecting the frequency at which alternating vortices are shed from a bluff body, which is hit by the medium. These shed vortices are carried downstream in the flow and are detected by vortex shedding and fluidic flow meters, which measure thevelocityof liquids and gases such as water,cryogenicliquids,boiler feed water,hydrocarbons, chemicals, air, nitrogen,industrial gases, and. (610 mm) diameter vortex shedding meter with a typical blockage ratio of 0.3 would only have a full scale frequency output of approximately 5 hz at 10 ft/s (3 m/s) fluid velocity.
Vortex shedding flow meter with temperature and pressure compensation is one of the main flow instruments,which is widely used in the industry of petroleum, chemical, metallurgy and heat supply,etc.it can measure and calculate the flow of liquids, gases and steams.
The differential pressure flow measuring principle (pitot tube). High precision vortex air flowmeter gas flow meter steam flow meter made in china 1.are you a trade company or a manufacturer9 kaifeng shengda there are 157 suppliers who sells vortex shedding flow meter on alibaba.com, mainly located in asia. Vortex flow meters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body. The microprocessor in the flowmeter can automatically correct for.
