Abstract:
A multi-configuration ultrasonic gas meter assembly having at least first and second assembly configurations, comprising:a first housing member including a back enclosure portion, a front portion spaced from the back enclosure portion to define an internal space, and wall portions extending between the back enclosure portion and the front portion, one of the wall portions having a first opening and a second opening therethrough for connection to a gas inlet pipe and a gas outlet pipe; a flow tube assembly including a gas flow measurement tube for positioning at least partially within the internal space of the first housing member and having a gas inlet end and a gas outlet end; at least one ultrasonic transducer positioned proximate the gas flow measurement tube for directing an ultrasonic signal along at least a portion of a length of the gas flow measurement tube; and wherein the first assembly configuration includes the gas flow measurement tube positioned within the internal space of the first housing member such that the first and second openings each face in a same first direction and gas travels in the first opening, through the gas flow measurement tube from the gas inlet end to the gas outlet end, and out of the second opening, and the second assembly configuration includes the gas flow measurement tube positioned within the internal space of the first housing member such that the first and second openings each face in a same second direction which is substantially opposite the first direction and in which gas travels in the second opening, through the gas flow measurement tube from the gas inlet end to the gas outlet end, and out of the first opening.
