A simple heat input and gas rate calculator for timing Natural Gas installations.

Very similar to the free version but with the added ability to change the Calorific Value of the gas, AND now you dont need to time an Metric Meter for two minutes shorter times can be used but longer times can be more accurate...

Time the Metric meter for two minutes, input the first and second reading, press calculate and your answer is there.

For imperial meters time one revolution then convert the time into seconds. input that time, press calculate and your answer is there.

No more looking up charts or using long winded calculations... Its so simple
