True energy calculation
During test and verification the heat meter’s energy calculation is compared to the ”true energy” calculated
according to the formula of EN 1434-1:2004 or OIML R75:2002.
An energy calculator like the one shown below can be ordered from Kamstrup A/S:
The true energy at the most frequently used verification points is indicated in the table below.
