General description

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.
The most basic configuration of a bubble flowmeter is a calibrated tube, a stopwatch, and a good eye. The bubble is timed as it moves up the calibrated tube between two markings. Flow tubes are graduated as follows:
  • 10 mL tube in 1 mL increments
  • 25 mL tube in 5 mL increments
  • 50 mL tube in 10 mL increments
  • 100 mL tube in 20 mL increments
Includes glass flow tube with two magnetic clamps, a short piece of Tygon tubing and a squeeze bulb. Stand not included.

Application

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.[1]
