Abstract: the precession vortex flowmeter scale and scale vortex flowmeter fundamental difference information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. First of all, though, these two kinds of flowmeter is the use of fluid oscillation of the principle of flow meter, but separately using two different works. Vortex flowmeter is by using the theory of karman vortex flowmeter: when fluid through a cylindrical object, in this. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a type of precession vortex flowmeter scale and vortex flow meter scale the fundamental difference between article details. First of all, though, these two kinds of flowmeter is the use of fluid oscillation of the principle of flow meter, but separately using two different works. Vortex flowmeter is by using the theory of karman vortex flowmeter: fluid after a cylindrical objects, and can produce vortices on either side of the object back to fluid, depressed when side vortex happens on the other side of the spiral, when on one side of the vortex development to a certain extent from columnar objects follow fluid and to produce new vortex in situ, at the same time, on the other side of the vortex loss of repression and happen, and stressed the new vortex, alternately on each side of pillars above process, the frequency of associated with the flow velocity of fluid, detecting the frequency velocity can be obtained, and then flow value is obtained. Due to release of vortex behind alternately fluid as the road on both sides of the object in the general arrangement, so this kind of phenomenon is also called the vortex. According to the principle of the work of the flowmeter is called vortex street flowmeter or karman vortex flowmeter. Precession vortex flowmeter is the use of precession model: principle of vortex flowmeter in the pipeline is set a group of twisted blade vortex generator, rotating in the fluid passes, and form vortex near the center line of the pipeline, the vortex at the center of the side revolve around the center line of the pipeline, along with the fluid forward while expanding radius of turn, makes the vortex center into a similar precession of conical spiral movement. At this time in the vortex generator on the rear wall of a point, it will happen through the fluid velocity of a cyclical change, its frequency associated with the flow velocity of fluid, detecting the frequency velocity can be obtained, and then flow value is obtained. According to the principle of the work of the flowmeter is called vortex precession flowmeter or type of vortex flowmeter vortex flowmeter is generally refers to the vortex flowmeter. Measuring gas, steam and liquid medium. It is to use the principle of karman vortex street flowmeter. Main structures include circular measuring tube, vortex occurred ( Triangle, cylindrical, etc. ) , sensing head, temperature and pressure components, etc. Precession vortex flowmeter is a kind of special measuring gas of a meter. Mainly consists of a venturi sounding pipe body, on the front and rear rectifier, sensing head, and the temperature and pressure components. The above information is provided by golden lake dahua automation instrument and hope will be helpful to you. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
