About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Flowmeters for Oxygen
To prevent contaminating your oxygen line, these flowmeters are specially cleaned and bagged. As oxygen flows through, it pushes an indicator up the scale, showing you the flow rate. Mount these flowmeters vertically inline with your oxygen system, so oxygen flows up from the bottom. The flow-control knob lets you open and close the valve at the inlet to adjust the flow rate within the range.
These flowmeters are calibrated with oxygen but can be used with other gases. If you’re using these with a gas other than oxygen, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your gas.
