Gas Rate Calculator & Guide
The app has the following features:
✔ Built-in let-by/tightness testing timers ✔ Built-in conversion calculator ✔ Built-in guide with full gas rate calculations and let-by/tightness testing procedure ✔ Works on all types of meter ✔ 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 timer alert ✔ Supports ¼ft³, ½ ft³ 1ft³, 2ft³ and 5ft³ imperial test dials ✔ Built-in torch ✔ Email results to any destination or share to other apps such as DropBox and Drive ✔ 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)
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 guide has been built into the app with 6 pages:
• Metric gas rate calculations
• Imperial gas rate calculations
• Heat input calculations
• Let-by test procedure
• Tightness test procedure
• Tightness test permissible pressure drops
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, 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 (MJ/h, kW and BTUs per hour) based on the CV.
The Tightness Testing function allows you to quickly select between the let-by and tightness tests and has an easy to use timer. No longer do you need to fiddle about with your phone's timer!
Calorific values can be entered manually (and saved) for more accurate gas rate calculation 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.
A torch function is included with this app if your device has an LED flash.
This app requires the CAMERA permission to use the LED flash as a torch.

Use this all the time. would be nice to have some guidance on the prepay meters and also the new smart meters. I personally know how to gas rate on these. But i come across alot of lads and ladies who dont.
Excelent app used the lite version first which was good the paid version is well worth it. Easy to use in metric or imperial Usefull conversion application built in Definateley recomend
Have always purchased Mr combi apps always up to date and spec and accurate I love supporting things that actually work!
was great but installed on S10 plus and calculator is well out. update its come back to life
Easy to use and plenty of information
Great, with remind information.
it's ok could do with decimal points
I think the most accurate app has I come across
Great app very simple to use but does the job.
Great app I use it every day very happy
Has got everything basic necessity you need
Very good app. Use it every day, hipe you make a commercial pipe sizing one thanks
Saves me a load of hassle, especially doing lgsr all day.
Gave 5 stars, a setting for 1/2' dial would be great tho!
I use it daily and it's quick and easy to use with all the info needed
Excellent app, the torch function is a nice touch- especially when you're in a dark cupboard! One sugestion- a simple BTU/KW converter (e.g. multiply or divide by 3412 accordingly) would come in handy
HTC one X Excellent app really would recommend it to any Gas Safe registered engineer ;-)
Don't work on electronic meters
Use it all the time great when you on the job
Simple use with large screen, saves getting back in the tool bag for gas rates.
I use this everyday. An excellent application. Great time saver.
I like the app but I noticed a bug if your screen turns off it stops the timer counting down. What's the point in that. Could do with either not allowing the screen to turn of or better still just let the timer run in the background.
