CO2 FLOWMETER

  • Calibrated to accurately deliver CO2 to ANY Chamber.
  • Small profile with an easy to set Flow-Rate and 3-way ball valve for quick chamber fill when needed.
  • Barb fitting for connecting to 5/16" or 1/4" ID hose. Wall-mount option.

Example Calculations for 20% Chamber Vol/min
Large Rat Cage

19” x 10” x 8” = 1520 in3.
1520 in3 x 0.20 = 304 in3 (flow rate wanted 304 in3/min).
304 in3/min divided by 61.024 = 4.98 l/min AIMS CO2flowmeter setting.

π x Radius2 x Height
3.14 x 4”2 x 7” = 352 in3.
352 in3 x 0.20 = 70 in3 (flow rate wanted 70 in3/min).
70 in3/min divided by 61.024 = 1.15 l/min AIMS CO2flowmeter setting.


Which CO2 Flowmeter to use? Calculate the total volume of your chamber in cubic inches (in3). Your chamber volume should fall between the min and max of the selected CO2 flowmeter for the selected Chamber Displacement Rate (CDR).

AVMA Guidelines for CO2 Euthanasia
General recommendations—Carbon dioxide is acceptable......using a gradual fill method is less likely to cause pain due to nociceptor activation by carbonic acid prior to onset of unconsciousness; a displacement rate from 10% to 30% of the chamber volume/min is recommended......... The practice of immersion, where conscious animals are placed directly into a container prefilled with 100% CO2, is unacceptable. From AVMA Guidelines for the Euthanasia of Animals:2013 Edition.
