The RTM3 flowmeters are pressure compensated flowmeters #1 that delivers an accurate prescribed flow of gas to the patient from a regulated pressure gas source. They are suitable for most types of respiratory therapy. They are available for use with oxygen, air, carbon dioxide, and carbogen, air/oxy mixture, and in a range of different flow capacities.
All models, except the 1.5 l/min model, have a flush flow feature that allows a flow of approximately 50 l/min when the flow control spindle is wound completely open, (the 1.5 l/min model maximum flow is limited to 6 l/min).
All models can be fitted with an optional maximum flow-limiting orifice by adding the suffix R after the part number. This orifice will limit the maximum flow from a 5 l/min model to a maximum of 10 l/min, from a 15 l/min model to 22 l/min and from a 30 l/min to 40 l/min
