美国SKC电子皂膜流量计ULTRAFLO
美国SKC气泡膜校准仪，也被称为皂膜流量计，用于精确校准采样器。用膜流量计，流速是根据测量仪器固有的，不变的特性。
一级标准
简单的使用
样品只接触玻璃和不锈钢
刻度线包围方便阅读的管
SKC流量计ULTRAFLO要校准的取样泵附在含有少量液体肥皂的体积玻璃管的顶部。由于泵把空气通过管子，平坦的肥皂泡插在流动路径。当气流使肥皂膜从一个体积标记移动到另一个体积时，用秒表测量旅行时间。流量可以直接计算使用的旅行时间和已知的管体积，或它可以读取从流程图。测试是快速和容易执行。
流量计组件被校准到一个主标准，在流量计上标注的体积的2%。

外文参考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.
