Calculation for Metric (kW)
A calorific value (CV) for the fuel must be entered into the calculation.
Click on:
Edit the '1' in the above calculation and add the calorific value for your fuel type.
The calorific value (CV) must be entered in units of kJ / m
Qv = Flowrate measured on Input 5 in m³ / hr
Depending on the output of the fuel flowmeter a unit correction may be required to convert the
calculation into seconds. For example, Qv*CV / 3600. Where 3600 converts from / h to / sec
Calculation for Imperial (MBtu / h)
A calorific value (CV) for the fuel must be entered into the calculation.
Click on:
Edit the '1' in the above calculation and add the calorific value for your fuel type.
The calorific value (CV) must be entered in units of Btu / ft
Qv = Flowrate measured on Input 5 in ft³ / m
Depending on the output of the fuel flowmeter a unit correction may be required to convert the
calculation into hours. For example, Qv*CV *60. Where 60 converts from / m to / h
