ABSTRACT:
A gas flow rate measuring device which is capable of removing a probe from a probe socket for inspection and/or replacement at the same time that while gas is flowing through a pipe. The gas flow rate measuring device includes a gas seal mechanism sealedly arranged between the probe socket and a probe coupler. The gas seal mechanism is formed therein with a hollow passage sufficient to allow the probe and a probe support to be moved therein and serves to hermetically seal the probe socket when the probe is removed from the probe socket. The gas flow rate measuring device may also include a ring member fitted on the probe support in a manner to be interposed between the probe support and the probe socket, arranged to prevent the transmission of a roundabout ultrasonic wave.
