13.6 True energy calculation
During test and verification the heat meter’s energy calculation is compared to the ”true energy”, which is calculated
according to the formula of EN1434-1:2015 and OIML R75:2002.
The below-mentioned energy calculator can be supplied electronically by Kamstrup A/S.
The true energy at the most frequently used verification points is indicated in the table below:
