什麼是渦流流量計
渦流流量計的組成
渦流流量計,包括:流量感測器,其可操作以感測由於流體在通道中的渦流脫落引起的壓力變化,並將壓力變化轉換為電信號形式的流量感測器信號;以及信號處理器,其用於接收流量感測器信號,並生成與由於通道中流體渦流脫落而引起的壓力變化相對應的輸出信號。
工作原理
當介質以一定速度流過布拉夫體時,在布拉夫體側面的後面會產生交替排列的渦流帶,稱為“馮·卡爾曼渦流”。由於渦流發生器的兩側交替產生渦流,因此在發生器的兩側都會產生壓力脈動,這會使檢測器產生交變應力。封裝在檢測探頭主體中的壓電元件在交變應力的作用下產生與渦旋頻率相同的交變電荷信號。這些脈衝的頻率與流量成正比。信號經過前置放大器放大後,發送到智能流量累加器進行處理
在雷諾數的一定範圍內(2×10 ^ 4〜7×10 ^ 6),渦流釋放頻率,流體速度和渦流產生器面對流動表面寬度之間的關係可以用以下公式表示:
f=St×V/d
其中,f是卡門渦流的釋放頻率,St是Strouhal數,V是速度,d是三角形圓柱的寬度。
渦流流量計的應用
1.智慧管道監控應用
流量計在工業應用中很受歡迎的主要原因是其設計和製造方式。它們沒有運動部件,幾乎沒有阻礙直通的流路,不需要溫度或壓力校正,並在很寬的流量範圍內保持精度。通過使用雙板流量調節元件可以減少直管段,並且安裝非常簡單,並且不會造成管道侵入
但是,在許多應用中,流體的熱性能可能取決於流體成分。在此類應用中,實際操作期間流體成分的變化會影響流測量。因此,對於流量計供應商而言,重要的是要了解流體的成分,以便可以使用適當的校準係數來準確確定流量。供應商可以為其他氣體混合物提供適當的校准信息,但是流量計的精度取決於實際的氣體混合物與用於校準目的的氣體混合物相同。換句話說,如果實際流動的氣體具有不同的成分,則針對給定的氣體混合物校準的流量計的精度將會降低
2.CVD設備
甚麼是CVD設備
氣相沉積(CVD)是一種真空沉積方法,用於生產高質量,高性能的固體材料。該工藝通常在半導體工業中用於生產薄膜
在典型的CVD中,晶片(基材)暴露於一種或多種易揮發的前體中,該前體在基材表面上發生反應和/或分解以產生所需的沉積物。通常還會產生揮發性副產物,這些副產物會被流過反應室的氣流除去

What is Vortex flow meter
Composition of vortex flowmeter[edit]
A vortex flowmeter comprising: a flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal,in the form of an electrical signal;and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to vortex-shedding of the fluid in the passage.[2]
Working principle[edit]
When the medium flows through the Bluff body at a certain speed,an alternately arranged vortex belt is generated behind the sides of the Bluff body, called the “von Kármán vortex“. Since both sides of the vortex generator alternately generate the vortex,the pressure pulsation is generated on both sides of the generator,which makes the detector produce alternating stress. 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 directly proportional to flow rate. The signal is sent to the intelligent flow totalizer to be processed after being amplified by the pre-amplifier.
In certain range of Reynolds number(2×10^4~7×10^6),the relationship among vortex releasing frequency, fluid velocity, and vortex generator facing flow surface width can be expressed by the following equation:[3]
f=St×V/d
Wherein, f is the releasing frequency of Carmen vortex,St is the Strouhal number, V is velocity, and d is the width of the triangular cylinder.[4]
Vortex Flow meter application
1.Smart piping monitor
The primary reason thermal mass flow meters are popular in industrial applications is the way they are designed and built. They feature no moving parts, nearly unobstructed straight through flow path, require no temperature or pressure corrections and retain accuracy over a wide range of flow rates. Straight pipe runs can be reduced by using dual-plate flow conditioning elements and installation is very simple with minimal pipe intrusions.
However, in many applications, the thermal properties of the fluid can be dependent upon fluid composition. In such applications, varying composition of the fluid during actual operation can affect the thermal flow measurement. Therefore, it is important for the thermal flow meter supplier to know the composition of the fluid so that the proper calibration factor can be used to determine the flow rate accurately. Suppliers can provide appropriate calibration information for other gas mixtures, however the accuracy of the thermal flow meter is dependent on the actual gas mixture being the same as the gas mixture used for calibration purposes. In other words, the accuracy of a thermal flow meter calibrated for a given gas mixture will be degraded if the actual flowing gas has a different composition.[2]
2.CVD machine
What is CVD
hemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.
In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit. Frequently, volatile by-products are also produced, which are removed by gas flow through the reaction chamber.
Microfabrication processes widely use CVD to deposit materials in various forms, including: monocrystalline, polycrystalline, amorphous, and epitaxial. These materials include: silicon (dioxide, carbide, nitride, oxynitride), carbon (fiber, nanofibers, nanotubes, diamond and graphene), fluorocarbons, filaments, tungsten, titanium nitride and various high-k dielectrics.
