Solving Oxygen Flow Rate Issue with One Cylinder

[tacticsnz]

I am trying to solve an oxygen flow rate issue that has me confused.

The goal is to have one portable oxygen cylinder (1500psi) provide 2 lines of oxygen at 15 litres/min.
The current oxygen cylinder is fitted with a regulator and flow meter that provides 0-15 litres/min.

I understand that if I were to simply attach a Y-connection I wouldn't get the full flow rate through each tube. However, cost if a factor and I am aiming to solve this without having to replace the regulator or flow meter.

Is there a way? (It is fine if both oxygen lines provide the same oxygen output, however both should equal up to 15 litres/min.)

Welcome to PF.
You seem to be suggesting that you could get two lots of 15l/minute from a single 15l/minute supply. That is clearly not possible so what exactly do you mean? You could try drawing a diagram, perhaps.

Thanks sophiecentaur. You're right that I need two 15L supplies. What I have is the oxygen with a regulator and flow meter and need to somehow provide two lines.

It looks like the only possible way is to change the flow meter or have two flow meters. What do you think?

It looks like it to me, too!

I would recommend exploring alternative solutions to achieve the desired oxygen flow rate without replacing the regulator or flow meter. One potential solution could be to use a flow splitter, which can evenly divide the oxygen flow from one source into two lines. This could potentially provide the 15 litres/min flow rate desired for each line. However, it is important to carefully consider the specifications and compatibility of the flow splitter with the existing equipment to ensure safe and effective results.

Another option could be to optimize the flow rate settings on the regulator and flow meter to achieve the desired flow rate for both lines. This may require some experimentation and fine-tuning, but it could potentially be a cost-effective solution.

Additionally, I would recommend consulting with a medical professional or oxygen equipment specialist to ensure the safety and effectiveness of any modifications made to the oxygen delivery system. It is important to prioritize the well-being and health of the individual receiving the oxygen.

In conclusion, while replacing the regulator or flow meter may seem like the most straightforward solution, it is worth exploring alternative options to potentially save on cost and find a feasible solution that meets the desired oxygen flow rate.
