Issues related to the usage of high-pressure gas cylinders
Thread Content
We often use helium in cylinders here; the internal pressure when it arrives is 140 kilograms, and we reduce it to 10 kilograms before using it. I’d like to install a gauge to keep track of how much helium has been used and how much is left after each use. What kind of gauge should I use?
Can’t you calculate it based on the pressure and volume before and after use?
Agree with the second floor; the idea from the third floor is a bit complicated!
For this, you can use a weighing scale to record the data on weight and pressure, do the calculations, create a statistical table, and then simply look up the weight in the table
