What is a vortex flowmeter
The composition of the vortex flowmeter
A vortex flowmeter, comprising: a flow sensor operable to sense pressure changes due to vortex shedding of fluid in a channel and convert the pressure changes into flow sensor signals in the form of electrical signals; and a signal processor , which is used to receive the flow sensor signal and generate an output signal corresponding to the change in pressure due to vortex shedding of the fluid in the channel.
working principle
When the medium flows through the Braff body at a certain speed, alternately arranged vortex bands are generated behind the sides of the Braff body, called "von Kalman vortices". Since eddy currents are alternately generated on both sides of the vortex generator, pressure pulsations are created on both sides of the generator, which can cause alternating stress to the detector. The piezoelectric element encapsulated in the detection probe body generates an alternating charge signal with the same frequency as the vortex under the action of alternating stress. The frequency of these pulses is proportional to the flow rate. After the signal is amplified by the preamplifier, it is sent to the intelligent flow accumulator for processing
In a certain range of Reynolds number (2×10^4~7×10^6), the relationship between the vortex release frequency, fluid velocity and the width of the vortex generator facing the flow surface can be expressed by the following formula:
f=St×V/d
where f is the release frequency of the Karman vortex, St is the Strouhal number, V is the velocity, and d is the width of the triangular cylinder.
The application of vortex flowmeter
1. Smart pipeline monitoring application
The main reason for the popularity of flow meters in industrial applications is the way they are designed and manufactured. They have no moving parts, have virtually no obstruction to a straight flow path, require no temperature or pressure correction, and maintain accuracy over a wide flow range. Straight pipe runs can be reduced by the use of double-plate flow conditioning elements, and installation is very simple and does not cause pipe intrusion
However, in many applications the thermal properties of the fluid may depend on the fluid composition. In such applications, changes in fluid composition during actual operation can affect flow measurements. Therefore, it is important for flow meter suppliers to understand the composition of the fluid so that the appropriate calibration factors can be used to accurately determine flow. Vendors can provide appropriate calibration information for other gas mixtures, but the accuracy of the flowmeter depends on the actual gas mixture being the same as the one used for calibration purposes. In other words, the accuracy of a flowmeter calibrated for a given gas mixture will decrease if the gas actually flowing has a different composition
2. CVD equipment
What is CVD equipment
Vapor deposition (CVD) is a vacuum deposition method used to produce high-quality, high-performance solid materials. This process is commonly used in the semiconductor industry to produce thin films
In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors that react and/or decompose on the surface of the substrate to produce the desired deposit. Often volatile by-products are also produced, which are removed by the gas flow through the reaction chamber

When the medium flows through the Braff body at a certain speed, alternately arranged vortex bands are generated behind the two sides of the Braff body, which are called "Von Karman vortices". Since eddy currents are alternately generated on both sides of the vortex generator, pressure pulsations are generated on both sides of the generator, which causes alternating stress on the detector. The piezoelectric element encapsulated in the detection probe produces an alternating charge signal with the same frequency as the eddy current under the action of alternating stress. The frequency of these pulses is directly proportional to the flow rate. After the signal is amplified by the preamplifier, it is sent to the intelligent flow totalizer for processing.
Within a certain Reynolds number range (2×10^4~7×10^6), the relationship between the vortex release frequency, fluid velocity and the width of the upstream surface of the vortex generator can be expressed by the following formula:[3]
f=St×V/d
Among them, f is the release frequency of Karman vortex, St is the Strouhal number, V is the velocity, and d is the width of the triangular prism [4].
Vortex Flowmeter Application
1. Smart Pipe Monitor
The main reason thermal mass flow meters are popular in industrial applications is the way they are designed and manufactured. They have no moving parts, a virtually unobstructed, straight-through flow path, require no temperature or pressure correction, and maintain accuracy over a wide range of flow rates. The use of a double plate flow regulating element allows for less straight piping and very easy installation with minimal piping intrusion.
In many applications, however, the thermal properties of a fluid may depend on the fluid composition. In such applications, changes in fluid composition during actual operation can affect thermal flow measurements. Therefore, it is important for thermal flow meter suppliers to know the composition of the fluid so that the flow can be accurately determined using the appropriate calibration coefficients. Suppliers can provide appropriate calibration information for other gas mixtures, but the accuracy of a thermal flow meter depends on whether the actual gas mixture is the same as that used for calibration purposes. In other words, the accuracy of a thermal flow meter calibrated for a given gas mixture will decrease if the gas actually flowing has a different composition. [2]

Chemical Vapor Deposition (CVD) is a vacuum deposition method used to produce high quality, high performance solid materials. The process is commonly used in the semiconductor industry to produce thin films.
In typical CVD, a wafer (substrate) is exposed to one or more volatile precursors that react and/or decompose on the substrate surface to produce the desired deposit. Often, volatile by-products are also produced, which are removed by the gas flow through the reaction chamber.
Micromachining processes widely use CVD to deposit various forms of materials including: single crystal, polycrystalline, amorphous and epitaxy. These materials include: silicon (silicon dioxide, carbides, nitrides, oxynitrides), carbon (fibers, nanofibers, nanotubes, diamond, and graphene), fluorocarbons, filaments, tungsten, titanium nitride, and various High-k dielectric.
