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
包含带有两个电磁夹的玻璃流量管，一小段Tygon管和一个挤压灯泡。 不包含立架。

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.
