Why is the gas cylinder empty after only a few uses?
Make sure you disconnect the regulator/flow valve from the calibration cylinder during storage as this may cause gas leak if the valve of the regulator/flow valve is not fully closed.
If possible, keep a record of the cylinder usage. This way the amount of gas left in the cylinder will be known.
