    Abstract - (Show below) - (Hide below)

    Describes requirements and tests for the construction, performance and safety of battery powered ultrasonic gas meters (hereinafter referred to as meters), having co-axial single pipe, or two pipe connections, used to measure volumes of distributed fuel gases of the first and/or second and/or third family, as given in EN 437, at maximum working pressures of up to 0,5 bar and maximum actual flow rates of up to 10 m[3]/h over a minimum ambient and gas temperature range of -10 degree C to +40 degree C, for domestic applications. It also applies to meters where the measuring element and the register(s) are enclosed in the same case.
