，需定做

。">Note: the wetted materials for use in 316, is a model for the LZB-Bo, can be customized.

。">For stainless steel PTFE is type LZB-BF (or BoF), can be customized.

、選用方法：">Six, selection method:

。">1, measurement. 、壓力大小、化學(xué)性質(zhì)

。">Measuring the media type, size, pressure and chemical properties. 、氣體介質(zhì)，對具腐蝕性的介質(zhì)則應(yīng)選擇耐腐流量計

。">Such as liquid and gas medium, the corrosive medium should choose corrosion resistance meter.

、流量計本身性能。">2, the performance of flowmeter.

，若價格沒有大的變化

，可優(yōu)先選用針閥置于流量計上部的；有較大流通孔的

，是直接流量刻度的

；結(jié)構(gòu)簡單的；外部尺寸較小的等等

。">The above conditions are identified in general, if the price is no big change, may be preferred needle valve is arranged on the upper part of the large circulation flow meter; hole, direct flow scale; simple structure; small exterior dimensions etc.. ，則可選用球浮子式，因它測量時穩(wěn)定

、不易積塵

。">Generally speaking, the high price of high precision. ，經(jīng)試運(yùn)行調(diào)整

，以后需始終穩(wěn)定這個通過量，那么精度就是次要的

。">According to the measurement instruments such as precision grade, only through the medium of control measure, the operation adjustment, after always stabilize the throughput, so the accuracy is minor.

、使用注意事項：">Seven, matters needing attention:

、不要把前罩殼去掉使用，因為玻璃管易爆破

，罩殼起到保護(hù)作用

。">1, don't put the front cover removed, because the glass tube easy blasting, shell to protect.

，應(yīng)當(dāng)注意保暖

，如果夜間不使用，要把流量計內(nèi)殘留液體放掉

，免得把玻璃管凍破

。">2, when used in winter, should pay attention to keep warm, if the night is not used, the residual liquid in the flow discharged, so as not to freeze broken glass tube.

，首先要看上

、下游管道是否在一條直線上

。">3, to the pipeline installation, first look at the downstream pipeline is in a straight line.

，不僅會影響儀表的測量準(zhǔn)確度，而且會損壞流量計

。">If not in a straight line, will not only affect the measuring accuracy of the instrument, but also will damage the flowmeter.

、開啟閥門時，一定要緩緩的開啟

，如果估計流量能夠浮動轉(zhuǎn)子

，而轉(zhuǎn)子并沒有向上移動，立即停止繼續(xù)開閥

，輕輕敲打管道

，使轉(zhuǎn)子能慢慢的上升。">4, when the valve is opened, will slowly open, if the estimated flow to floating rotor, and the rotor does not move up, immediately stop valve, tap the pipeline, so that the rotor can slowly rise.

、首先觀察流量計內(nèi)的玻璃管是否完好

，玻璃管極易破損；其次是去掉轉(zhuǎn)子的固定物

，輕輕的倒向看轉(zhuǎn)子能否自由的上下滑動

。">5, first observed within the flow tube is intact, glass tube is easy to damage; second is to remove the rotor fixture, gently slide backward to see whether the rotor freely up and down.

。">If not free to slide, vibration plate gently.

，就需要請專業(yè)人員解決。">If we can not slide, would need professional solutions.
