氣體質量氣密性檢測裝置流量計的優點有哪些？

目前所用各種型式的氣體流量計，絕大部分是計量氣體的體積流量。由于氣體的體積隨溫度與壓力的不同而變動，所以常發生較大的計量誤差。如工作壓力經常變動，更使計量發生困難。 氣體質量氣密性檢測裝置流量計的(de)(de)主要(yao)特點是不受溫度與(yu)壓(ya)力變動的(de)(de)影響，其顯示讀數直接(jie)指示氣體的(de)(de)質員流量。它具有一(yi)系(xi)列(lie)優點：

At present, the gas flowmeter types, most of the gas volume flow measurement. While changes due to the different gas volume with temperature and pressure, so often happen measurement errors. If the pressure changes frequently, more make the measurement difficulties. The main characteristics of gas tightness detection device quality flow meter is not influenced by temperature and pressure changes, quality staff flow readings directly indicate the direction of gas. It has a series of advantages:

1. 在常壓、高壓或負壓的條件下均可選用。

1 can be used in atmospheric pressure, high pressure or negative pressure condition.

2. 可在常(chang)溫(wen)、100度(du)，甚至又高的溫(wen)度(du)下正常(chang)運行(xing)。

2 in the normal temperature, 100 degrees, normal operation and high temperature.

3. 適用(yong)的量程范(fan)圍寬，既能(neng)用(yong)于實驗室(shi)內小流(liu)量的場(chang)所也可用(yong)于工廠生產中的大型裝置(zhi)。

3 applicable range wide, can be used not only for can also be used for large-scale equipment factory production of small flow in the laboratory in place.

4. 流量計的阻力降極微。

4 meter of resistance at.

5. 抗介質腐蝕的能力強。

5 anti corrosion ability.

6. 計量精度高。

6 high precision measurement.

7.輸(shu)出(chu)電訊號，可遠傳顯示，還便于(yu)與其他(ta)儀表配合(he)后實(shi)現流量(liang)(liang)(liang)記錄．自(zi)控(kong)或累計(ji)。 質量(liang)(liang)(liang)流量(liang)(liang)(liang)計(ji)是(shi)(shi)一種熱導式儀表早在本世紀初，托馬斯(Thomas)提出(chu)了(le)它(ta)(ta)的(de)原型，后幾經變革慚趨完善。目(mu)前許(xu)多國家有(you)(you)這類流星計(ji)的(de)工(gong)業(ye)產(chan)品，廠泛應用(yong)于(yu)各個工(gong)業(ye)生產(chan)及(ji)科學實(shi)驗的(de)領域。雖具(ju)體(ti)(ti)結構各有(you)(you)差異，但其原理是(shi)(shi)基本一致(zhi)的(de)。我(wo)國自(zi)1976年以(yi)來(lai)，也已(yi)有(you)(you)幾種產(chan)品陸續間世，較多地應用(yong)于(yu)原子能(neng)工(gong)業(ye)及(ji)半導體(ti)(ti)制造工(gong)業(ye)。我(wo)們(men)曾用(yong)于(yu)80大氣壓(ya)微(wei)型催(cui)化反應裝置中計(ji)量(liang)(liang)(liang)氫氣流量(liang)(liang)(liang)，己取(qu)得了(le)成功(gong)的(de)經驗。若能(neng)把它(ta)(ta)推廣應用(yong)于(yu)石油、化工(gong)業(ye)的(de)各個方面必(bi)將(jiang)收到(dao)良(liang)好(hao)的(de)效(xiao)益。

The 7 output signals, remote display, convenient and implementation flow recording other instrument with automatic control or cumulative. Mass flowmeter is a kind of thermal conductivity instrument in the early years of this century, Thomas (Thomas) proposed its prototype, after several changes and perfect. At present this kind of meteor meter industrial products in many countries, is widely used in various industrial production and scientific experiments in the field. Although the concrete structure is different, but the principle is the same. Our country since 1976, also have several products have been among the world, widely applied to atomic energy industry and semiconductor manufacturing industry. We have used for the measurement of hydrogen flow rate of 80 atmospheric pressure micro catalytic reactor, has obtained the successful experience. If you can make it applied to petroleum, chemical industry, each will receive good benefit.
