一般描述

Bubble flowmeter is a simple and precise way to measure flow rates of gases. It determines the volumetric flow rate by measuring the time taken by the gas stream to move a soap bubble through a specific volume. Bubble flowmeters can be used to check splitter or detector flow or to calibrate personal pumps for accurate air sampling.
气泡流量计的最基本配置为校准管、秒表和好的眼力。气泡在两个标记之间沿校准管上移过程被计时。流量管的刻度如下：

• 10 mL管，以1 mL为增量
• 25 mL管，以5 mL为增量
• 50 mL管，以10 mL为增量
• 100 mL管，以20 mL为增量

应用

Bubble flowmeter may be used to manually control the flow at the system outlet during analysis of perfluorobutane (PFB) in the exhaled rat air using respiration-metabolism chamber system and a GC-MS method.
