1) The measuring device is capable of calculating the volume flow, and other measured variables derived from
the volume flow, across all steam types with full compensation using the pressure and temperature. To
configure device behavior →  110
2) Gross calorific value: combustion energy + condensation energy of the flue gas (gross calorific value > net
calorific value)
3) Net calorific value: only combustion energy
Mass flow and energy flow calculation
NOTICE
The process pressure (p) in the process pipe is required to calculate the process
variables and the limit values of the measuring range.
‣
With the HART device, the process pressure can be entered via the 4 to 20mA current
input or via HART from an external pressure measuring device (e. g. Cerabar M) or
entered as a fixed value in the External compensation submenu (→  110).
