Store description excerpt

Time the test dial. Enter the seconds. Get the answer. Gas Rate Calculator gives you gross and net heat input in every unit a UK gas engineer needs — kW, BTU/hr, ft³/hr, m³/hr, and l/hr. Covers U6 and E6 meters, natural gas, propane, and butane. HOW IT WORKS Time one complete revolution of the test dial on the meter, enter the reading, and the app instantly calculates gross and net heat input. Supports both imperial (U6) and metric (E6) dial meters. IMPERIAL (U6) METER Select your dial size (1/4, 1, 2 or 5 ft3/rev), enter the time in seconds for one complete revolution, and read off the results. The classic method used every day on service calls. METRIC (E6) METER Record the meter reading, wait exactly 2 minutes, record again. The app calculates consumption over that period and converts to heat input. No stopwatch needed for the test dial. RESULTS IN EVERY UNIT Each calculation gives you both gross and net values for: - kW - BTU/hr - Cubic feet per hour - Cubic metres per hour - Litres per hour THREE GAS TYPES - Natural Gas (CV 38.76 MJ/m3, gross/net ratio 1.11) - Propane (CV 93.1 MJ/m3, gross/net ratio 1.09) - Butane (CV 121.8 MJ/m3, gross/net ratio 1.08) SAVE AND COMPARE Name and save as many calculations as you like. Useful for logging readings across multiple appliances on the same job, or comparing before and after a service. History is stored locally and persists between sessions. NO SIGN-IN. NO ADS. NO DATA COLLECTED. All calculations run entirely on your device. Nothing is sent to any server. Built for iPhone. iOS 17 or later required.
