6.5 Calculating the quantity of gas
supplied
The quantity of gas supplied can be calculated if the system is equipped with
a gas flow meter of some type. The procedure here is usually to measure
how long it takes for the burner to consume a certain quantity of gas.
To measure:
t = Time for a certain quantity of gas consumed by the burner. [h]
M = Quantity of gas consumed. [m 3 ]
V = Actual gas flow [m

This means that the quantity of gas read from the gas meter should actually
be read off as 1.11 . the calculated flow in a normal state.
