Diagnosing or troubleshooting gas related issues at the appliance level is easier than ever with the FloPro-MD. The FloPro-MD removes the guesswork and offers you a means of determining gas pressure (psi), gas flow (CFH) and converting the information to heat output in BTU/hr. By doing so, it allows you to determine if the proper amount of gas is flowing to the equipment and the equipment is delivering the expected output per specifications. Thousands of service technicians and installers, like yourself, are out on the road today troubleshooting issues with gas burning equipment. Most of you use a manometer to determine gas pressure at the equipment, but do you know what the actual flow of gas is in cubic feet per hour (CFH) and the equivalent BTU/hr output capacity of that flowing gas? Probably not. Whether you are performing a start-up on a gas generator, a boiler or responding to a customer complaint that their appliance is not working as it should, you can feel confident that the information collected by the FloPro-MD will put both yours and your customer’s mind at ease. The FloPro-MD is a compact, light-weight, electronic device that can be easily installed in a matter of minutes. The installation could be temporary to verify proper gas flow during start-up and commissioning of gas equipment or for a longer period of time to log information to assist in troubleshooting a new or repeat problem. The FloPro-MD communicates via Bluetooth connectivity with any smart device. With the data that is collected by the device, a csv file is generated that can be emailed to you or your customer or a hard copy printed and submitted with a work report and/or filed.

Verdict
The clearest difference is rating: FloPro at 5.0 against Span Installer's 3.3. FloPro also leads on device support (3 vs 1) and iOS requirement (10.3 vs 17.6). Span Installer's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (15 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
