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主要特點是不受溫度與壓力變動的影響，其顯示讀數直接指示氣體的質員流量。它具有一系列優點：
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. 可在常溫、100度，甚至又高的溫度下正常運行。
2 in the normal temperature, 100 degrees, normal operation and high temperature.
3. 適用的量程范圍寬，既能用于實驗室內小流量的場所也可用于工廠生產中的大型裝置。
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.輸出電訊號，可遠傳顯示，還便于與其他儀表配合后實現流量記錄．自控或累計。 質量流量計是一種熱導式儀表早在本世紀初，托馬斯(Thomas)提出了它的原型，后幾經變革慚趨完善。目前許多國家有這類流星計的工業產品，廠泛應用于各個工業生產及科學實驗的領域。雖具體結構各有差異，但其原理是基本一致的。我國自1976年以來，也已有幾種產品陸續間世，較多地應用于原子能工業及半導體制造工業。我們曾用于80大氣壓微型催化反應裝置中計量氫氣流量，己取得了成功的經驗。若能把它推廣應用于石油、化工業的各個方面必將收到良好的效益。
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.
