| 摘要 |
An acoustic gas meter comprises an acoustic transmitter/receiver arrangement (2,4) disposed within a gas flow conduit (6) for transmitting and receiving acoustic energy along an acoustic path (8). A temperature probe (14) is included having an elongate sensor region (16) disposed relative to, preferably along, the acoustic path (8) to provide a measure of a gas temperature indicative of an average gas temperature within the acoustic path (8). <IMAGE> |
