Method for measuring a gas flow rate and a gasmeter therefore |
摘要 |
Gasmeter for determining a flow rate of gas within a channel is provided. The gasmeter includes a channel for passing through it a flow of gas along a first sensor and a chamber which is arranged for receiving and containing at substantially stand still gas from the channel and in which a second sensor is arranged. The sensors are heated during heating periods and subsequently let cooled down in cooling periods. The cooling rate of the sensors is determined and are used to calculate a value of the flow rate through the channel which is compensated for change of density of the gas.
