25. When the flow meter used for quantification purposes does not correct for the temperature and pressure of the biogas at standard conditions, the promoter must measure the biogas pressure and temperature separately and correct the flow values using Equation 12. The promoter must then use the corrected flow values for quantification purposes.

Equation 12: Correction of biogas volume at standard conditions

BGd,t = BGuncorrected ×	293.15	×	P
	T		101.325

Where:

BGt = Corrected volume of biogas sent to reclamation or destruction device d during time interval t, in cubic metres at standard conditions;

d = Reclamation or destruction device;

t = Time interval shown in Appendix E for which CH4 flow and content measurements are aggregated;

BGuncorrected = Uncorrected volume of the biogas captured during time interval t, in cubic metres;

T = Measured temperature of the biogas for the given time interval, in Kelvin (°C + 273.15);

P = Measured pressure of the biogas for the given time interval, in kilopascals.
