氣體質(zhì)量氣密性檢測裝置流量計的優(yōu)點(diǎn)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(fā)生較大的計量誤差。如工作壓力經(jīng)常變動，更使計量發(fā)生困難。 氣體質(zhì)量氣密性檢測裝置流量計的主要特點(diǎn)是不受溫度與壓力變動的影響，其顯示讀數(shù)直接指示氣體的質(zhì)員流量。它具有一系列優(yōu)點(diǎn)：
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(fù)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(yùn)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(shí)驗室內(nèi)小流量的場所也可用于工廠生產(chǎn)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(zhì)腐蝕的能力強(qiáng)。
5 anti corrosion ability.
6. 計量精度高。
6 high precision measurement.
7.輸出電訊號，可遠(yuǎn)傳顯示，還便于與其他儀表配合后實(shí)現(xiàn)流量記錄．自控或累計。 質(zhì)量流量計是一種熱導(dǎo)式儀表早在本世紀(jì)初，托馬斯(Thomas)提出了它的原型，后幾經(jīng)變革慚趨完善。目前許多國家有這類流星計的工業(yè)產(chǎn)品，廠泛應(yīng)用于各個工業(yè)生產(chǎn)及科學(xué)實(shí)驗的領(lǐng)域。雖具體結(jié)構(gòu)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(chǎn)品陸續(xù)間世，較多地應(yīng)用于原子能工業(yè)及半導(dǎo)體制造工業(yè)。我們曾用于80大氣壓微型催化反應(yīng)裝置中計量氫氣流量，己取得了成功的經(jīng)驗。若能把它推廣應(yīng)用于石油、化工業(yè)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.
