The invention discloses a plug-in thermal gas
mass flow meter capable of resisting vibration, and relates to the field of thermal gas
mass flow monitoring. The plug-in thermal gas
mass flow meter capable of resisting the vibration comprises an instrument
transmitter, a feeler lever and a measuring head, and the measuring head is connected with the instrument
transmitter through the feeler lever; the plug-in thermal gas mass flow meter further comprises a steel
pipe, a
flange and a locking structure, wherein the steel
pipe comprises a suspending section and a fixed section, the fixed section isused for penetrating through an
air channel wall to be installed and fixed, and the suspending section is used for being suspended at the inner side of the
air channel wall; the
flange is connected with the end of the fixed section of the steel
pipe and is used for being fixed to the outer wall of the
air channel wall, the feeler lever penetrates through the
flange and the steel pipe in sequence,and the measuring head stretches out of the end of the suspending section of the steel pipe; the locking structure is used for locking and fixing the feeler lever, the flange and the steel pipe. By means of the plug-in thermal gas mass flow meter capable of resisting the vibration, the influence of
airflow on the feeler lever is removed through the steel pipe, and it is guaranteed that the measuring head precisely measures the gas flow in the air channel, and the looseness between the feeler lever and the flange and the steel pipe can also be prevented.
