Abstract
A turbine gas flow meter (10) includes a meter body (12) including an inlet portion (24) having an inlet body (32) mounted therein, with an exit end (30) of the body inlet portion being defined at an internal plenum (22) of the meter body, and a removable turbine meter measuring module (44) including a rotor assembly (48) which is inserted into the plenum with an inlet end (127) of the rotor assembly and the exit end of the inlet portion defining an interface therebetween. A closed space (114) is formed about the rotor assembly within the plenum between an inner wall (106) of the body and outer walls (116, 118) of the rotor assembly. An axial gap (128) between a surface (130) of the rotor assembly inlet end and a surface (132) of the body inlet portion exit end, and/or radial notches in either of the surfaces (130, 132), provide fluid pressure communication from the interface to the closed space. A pressure tap (138) extends through the body into the closed space for measuring pressure within the closed space.
