==Flowmeters==

Flowmeters are made up of a transparent tube with either a bobbin or ball, which float in the gas flow. The flow rate is marked on the tubing, and the gas flows around the bobbin or ball, where if the flow increases then the marker will rise indicating a higher flow rate. If a bobbin is present then the flow rate is read from the top of the bobbin whereas if a ball is present then the flow rate is read from the middle point of the ball. Again, flowmeters are often colour coded for the gas that they are controlling, with oxygen commonly being white, while nitrous oxide is blue.

If a bobbin is present then the flow rate is read from the top of the bobbin whereas if a ball is present then the flow rate is read from the line of the equator.

Flowmeters are supported along with the vapourisers and some other components on the backbar of anaesthetic machines.
