7386182
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.
Removable Radio Frequency Sensor Assembly For A Turbine Flow Meter

International Classification:
G01F 1500
US Classification:
7386177
Abstract:
A sensor assembly for a fluid flow meter, more particularly a gas meter, includes a sensor well made of a non-magnetic material and a sensor which is removable from the well without depressurizing the fluid line in which the flow meter is located. The sensor well is mounted within a bore formed in a meter body boss and, in a preferred embodiment, extends through the internal rotor housing and includes an inner face contoured to conform to the inner wall of the housing. In certain embodiments of the invention, the sensor is shaped to cover the sensor well mounting bolts so that the well cannot be removed without first removing the sensor. In other embodiments, the sensor well mounting bolts are retained in the sensor well by dowel pins, stakes or retaining rings such that the bolts must be gradually and sequentially loosened to remove the sensor well, in order to prevent improper removal of the sensor well from the meter body boss. In still other embodiments, the sensor well is threaded directly into the body boss or includes a threaded collar and a sleeve which is rotatable to facilitate positioning of a contoured face relative to the housing inner wall. In such embodiments the body boss includes an annular recess which allows pressurized fluid to escape from between the sensor well and body boss as the sensor well is removed, thereby providing an audible warning that the line on which the meter is mounted is pressurized.
Tandem Rotor Turbine Meter And Field Calibration Module

Assignee:
M & FC Holding Company, Inc. - Wilmington DE
International Classification:
G01F 2500 G01F 700
US Classification:
73 3
Abstract:
Methods and an apparatus for measuring gas flow with greater reliability than earlier single-rotor and double-rotor turbine meters and dual turbine meter systems are disclosed. The apparatus comprises two independent rotors, in close proximity of each other, housed in the same meter body, but isolated from the effects of each other. No pressure and temperature correction are needed for accuracy performance comparison between the two rotors. Because of the two rotor averaging technique, the reliability of the volume totalization is greatly improved over earlier double-rotor and single-rotor designs.

International Classification:
G05D 16/06
Abstract:
A gas pressure regulator regulates a pressure of a gas system. The gas pressure regulator includes a first chamber, a first diaphragm which separates the first chamber into a first compartment and a second compartment, a second chamber, with a second diaphragm separating the second chamber into a third compartment and a fourth compartment, the fourth compartment being connected to, and in communication with, the first compartment of the first chamber. A movement of the first diaphragm causes a corresponding movement of the second diaphragm, and a change in the volume of the fourth compartment.
