摘要： A vent assembly for a double case, rotary positive displacement meter permits venting of the outer housing chamber and inner mechanism chamber simultaneously through a single port in the outer housing to prevent damage to the rotor of the inner mechanism. A float/reed switch assembly can be provided to provide an indication of the need for venting if the vent is manually operated, or to automatically vent if an electrically operated valve is used.

摘要： A temperature compensated fluid meter includes a temperature transducer with a bellows that expands and contracts. Movement of a rod attached to a movable end of the bellows is coupled to a transmission assembly which includes a cylinder and a cone that have a transfer ring mounted between them. The actuator rod is interconnected with the transfer ring to move it substantially linearly and continuously along the axis of the cylinder in response to changes in the temperature of the fluid being measured. This changes the speed of rotation of the cone with respect to the cylinder for a particular volume of fluid as the temperature of the fluid changes. A cone shaft in which the cone is mounted is interconnected with the compensated index within the register so as to substantially linearly and continuously cause the index to record a temperature compensated fluid volume. A pair of elastomeric expanders in the mounting assembly for the cylinder's shaft flex in response to a force exerted on the cone by a spring that biases the cone, mounted at an angle to the cylinder, toward the cylinder. The flexing of the elastomeric expanders minimizes the effects of discontinuities in the size and shape of the ring, the cylinder and the cone during their rotation. A register cover attached to the fluid meter has at least one side rib extending from a location adjacent each of a plurality of mounting holes in a mounting flange at an open end of the register cover. Radially extending closure ribs, corresponding to the side ribs, are located within the register cover and on a closed end of the cover and extend toward the center of the closed end. In some figures an end of each of the closure ribs is attached to a flange on the closure end of the register cover.

摘要： A flow prover with seal monitor includes a housing with a cylinder and a piston-like displacer sealingly conveyed along the cylinder by the fluid flow to be measured. The displacer includes at least one rod that extends telescopically through the housing. A pair of conduits may be arranged concentrically within the rod, one in communication with a volume between a pair of seals whose integrity is to be monitored and the other in communication with the fluid in the housing. The conduits each communicate as well with a pressure sensor located outside of the housing. The sensor may be mounted on the rod to sense the absence of a pressure differential between the conduits, which indicates a seal failure. The sensor may provide an indication, which may be detected at the end of a proving cycle, that the seal integrity was maintained throughout the proving cycle.
摘要翻译：具有密封监视器的流量检测器包括具有气缸和活塞式置换器的壳体，其通过被测量的流体沿着气缸密封地传送。置换器包括至少一个可伸缩地延伸穿过壳体的杆。一对管道可以同心地布置在杆内，一个管道与一对密封件之间的容积连通，其一体性被监控，另一个与壳体中的流体连通。导管也通过位于壳体外部的压力传感器进行通信。传感器可以安装在杆上以感测导管之间不存在压力差，这表示密封失效。传感器可以提供在证明循环结束时可以检测到的指示，即在整个证明循环中保持密封完整性。
