Abstract

See full text

A method for controlled dosing of a gas with fluctuating supply pressure (PSupply). Dosing of the gas through a valve (6) is performed while a valve (5) is closed, and the decrease in control-volume pressure (PCV) is recorded. The control-volume pressure (PCV) is raised by closing dosing valve (6) and opening the valve (5). The amount of the dosed gas is calculated based on the known volume (VCV) of the control volume (4) and at least one of the change in control-volume pressure (PCV) and control-volume temperature (TCV) in the period where valve (5) is closed. The amount of dosed gas is compared with a target or set-point to adjust or regulate the subsequent dosing period or dosing event.
