    Abstract - (Show below) - (Hide below)

    Describes requirements and tests for the construction, performance and safety of class 1,0 and class 1,5 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 second and/or third family, as given in EN 437, at maximum working pressures not exceeding 0,5 bar and maximum actual flow rates of up to 10 m3/h over a minimum ambient temperature range of -10 degrees C to +40 degrees C, and minimum gas temperature span of 40 K, for domestic applications.
