Gas Rate Calculator & Guide v1.3.5 Requirements:Android 2.1+ Overview: Try Mr Combi's Gas Rate Calculator! Use the Gas Rate Calculator to find gas rates (cubic metres per hour, cubic feet per hour and litres per second) and gross and net heat inputs in kW and BTUs per hour. Try Mr Combi's Gas Rate Calculator!
Use the Gas Rate Calculator to find gas rates (cubic metres per hour, cubic feet per hour and litres per second) and gross and net heat inputs in kW and BTUs per hour.
✔ Metric and imperial calculators ✔ Supports natural gas, butane and propane ✔ Save manual calorific values for improved accuracy ✔ Select between a 1 and 2 minute timer for metric meters ✔ Selectable metric timer alert ✔ Supports 1ft³, 2ft³ and 5ft³ imperial test dials ✔ Built-in torch ✔ Built-in guide with full gas rate calculations ✔ Extra calculator for conversions between gas rates and heat inputs ✔ Email results to any destination ✔ Timers do not reset when the device is rotated ✔ Timers will continue to run if the home button is pressed (metric alert will function also)
Calorific values can be entered manually (and saved) for more accurate results. The calorific value of natural gas in the UK varies from about 38.3 to 40.5 MJ per cubic metre; this can mean a difference in the gas rate calculation of more than 5%! With this calculator you can add the CV for your area in the settings page and avoid these inaccuracies. The default values set for butane and propane are both the same as supplied by Calor and BOC.
The metric timer can be set to either 1 or 2 minutes. For U6 and G4 meters one minute is sufficient, for E6 meters two minutes is recommended for accuracy. The timer can be set to an audible alert, vibrate, both or neither.
A torch function is included with this app if your device has an LED flash. Unfortunately we cannot guarantee that all devices are supported but it has been confirmed to work on:
For unsupported devices or those without an LED flash the torch icon can be hidden.
A guide has been built into the app with 5 pages: • Features of the app • App instructions • Metric gas rate calculations • Imperial gas rate calculations • Heat input calculations
An extra Quick Converter calculator is included in the app for simple conversions between gas rates and heat inputs. Simply select the type of gas or enter a manual calorific value, enter a value, select the units, press the 'Calculate' button and the calculator will show all gas rates (cubic metres per hour, cubic feet per hour and litres per second) and heat inputs (kW and BTUs per hour) based on the CV.
