美國(guó)SKC電子皂膜流量計(jì)ULTRAFLO

美國(guó)SKC氣泡膜校準(zhǔn)儀，也被稱為皂膜流量計(jì)，用于精確校準(zhǔn)采樣器。用膜流量計(jì)，流速是根據(jù)測(cè)量?jī)x器固有的，不變的特性。

一級(jí)標(biāo)準(zhǔn)

簡(jiǎn)單的使用

樣品只接觸玻璃和不銹鋼

刻度線包圍方便閱讀的管

SKC流量計(jì)ULTRAFLO要校準(zhǔn)的取樣泵附在含有少量液體肥皂的體積玻璃管的頂部。由于泵把空氣通過(guò)管子，平坦的肥皂泡插在流動(dòng)路徑。當(dāng)氣流使肥皂膜從一個(gè)體積標(biāo)記移動(dòng)到另一個(gè)體積時(shí)，用秒表測(cè)量旅行時(shí)間。流量可以直接計(jì)算使用的旅行時(shí)間和已知的管體積，或它可以讀取從流程圖。測(cè)試是快速和容易執(zhí)行。

流量計(jì)組件被校準(zhǔn)到一個(gè)主標(biāo)準(zhǔn)，在流量計(jì)上標(biāo)注的體積的2%。

SKC流量計(jì)ULTRAFLO性能參數(shù):

外文參考Bubble Film Calibrators, also known as soap film flowmeters, are used to accuray calibrate air samplers. With a film flowmeter, flow rates are based upon the inherent, unchanging properties of the measuring apparatus.

• Primary Standard
• Simple to use
• Sample contacts only glass and stainless steel
• Calibration lines encircle the tube for easy reading

The sampling pump to be calibrated is attached to the top of a volumetric glass tube containing a small amount of liquid soap. As the pump draws air through the tube, a flat soap bubble is interposed in the flow path. While the air flow causes the soap film to move from one volume mark to another, the travel time is measured with a stopwatch. The flow rate can then be directly calculated using the travel time and the known tube volume, or it can be read from the flow chart. The test is quick and easy to perform.

The Flowmeter Kits are calibrated to a primary standard, ±2% of the volumes marked on the flowmeter.
