摘要： A flow measuring device for measuring flow of a fluid. A housing has a passage which extends between an inlet and an outlet. A shaft is disposed within the housing and is rotatable about a central axis. A flow detector is mounted on the shaft and disposed at least partially within the passage. The flow detector includes a rotatable, generally cylindrical body that rotates about a central axis as the fluid flows. A magnet is mounted on the rotatable body or on the shaft, and is configured to rotate simultaneously with the body about the central axis. A sensor is disposed within the housing and configured to sense rotation of the magnet as the flow detector angularly displaces about the central axis so as to detect angular displacement of the flow detector.

摘要： Some embodiments of a meter device for measuring volume flow of gas can include bearings and the timing gears may each include a least one component comprising a ceramic material that enhances the wearability of the bearing and the timing gears. Accordingly, the gas flow meter can operate in a manner that reduces or eliminates the need for external oil lubrication of the bearings and the timing gears (e.g., the external oil lubrication conventionally provided by the oil bath compartment), and thus reduces the likelihood of failure of the gas flow meter due to leaks or failures of the oil bath compartment.

摘要： A cast-in-place and lithographically shaped mobile, monolithic polymer element for fluid flow control in microfluidic devices and method of manufacture. Microfluid flow control devices, or microvalves that provide for control of fluid or ionic current flow can be made incorporating a cast-in-place, mobile monolithic polymer element, disposed within a microchannel, and driven by fluid pressure (either liquid or gas) against a retaining or sealing surface. The polymer elements are made by the application of lithographic methods to monomer mixtures formulated in such a way that the polymer will not bond to microchannel walls. The polymer elements can seal against pressures greater than 5000 psi, and have a response time on the order of milliseconds. By the use of energetic radiation it is possible to depolymerize selected regions of the polymer element to form shapes that cannot be produced by conventional lithographic patterning and would be impossible to machine.

摘要： An improved industrial meter housing assembly includes a compactly designed metal housing having a central trefoil shaped chamber and minimal length inlet and outlet ports in fluid communication with the chamber with the ports ending at inlet and outlet port faces on the housing outer surface oriented 90.degree.degrees from each other and 45.degree.degrees to the vertical with the housing in its upright position. The housing may be installed as original equipment in an industrial environment having upstream pipe connections provided to match those input and output port faces. However, the compactness of the housing may be utilized together with a pair of installations-specific inlet and outlet runner pipes to enable the combination meter housing/runners to be substituted for any existing original equipment industrial meter. Additionally, the inlet and outlet ports of the compact meter housing are shaped to match the width and radius (area) of the displacement rotors, and the inlet and outlet runner pipe passageways are shaped to provide a smooth transition from the circular cross-section inlet and outlet fluid transmission pipes to the generally rectangular inlet and outlet port configurations. Further, the short inlet and outlet ports in the housing are curved to direct the fluid flow in a less turbulent manner to and from the displacement rotors rather than directing the fluid flow to and from the blocking rotor or between the blocking rotor and the displacement rotors.
摘要翻译：一种改进的工业仪表壳体组件包括紧凑设计的金属壳体，其具有中央三叶形腔室和与腔室流体连通的最小长度的入口和出口端口，其中端口在壳体外表面上的入口端口和出口端口处朝向90度彼此相距45度，垂直方向与壳体处于直立位置。壳体可以作为原始设备安装在具有提供以匹配那些输入和输出端口面的上游管连接的工业环境中。然而，壳体的紧凑性可以与一对特定的入口和出口流道管一起使用，以使组合仪表壳体/流道代替任何现有的原始设备工业仪表。此外，紧凑型仪表壳体的入口和出口被成形为匹配位移转子的宽度和半径（面积），并且入口和出口流道管通道成形为提供从圆形横截面入口和出口流体传输管道到大致矩形的入口和出口端口配置。此外，壳体中的短入口和出口弯曲，以将流体流以较少的紊流方式引导到位移转子，而不是将流体流引导到阻塞转子或阻塞转子与位移转子之间。

摘要： A flowmeter has two moving parts, a rotor with a cylindrical core and the radially extending sinusoidal curving vane. A slider has a gate opening which fits on the vane for reciprocating axially as the rotor turns. The slider and rotor are held within a cavity and slider recess within a case. Fluid is admitted through an inlet opening on one side of the slider and is exhausted through an outlet opening on the other side of the slider. A magnetic pickup on the slider indicates the movements of the slider, and hence the rotation of the rotor and the volume of fluid flowing through the meter.

摘要： A positive displacement apparatus usable as a pump or motor or flowmeter comprises a first revolving vane rotatably disposed in a first cylindrical cavity wherein the edge of the first revolving vane sweeps on a circular cylindrical portion of the cylindrical wall of the first cylindrical cavity, and a second revolving vane rotatably disposed in a second cylindrical cavity wherein the edge of the second revolving vane sweeps on a circular cylindrical portion of the cylindrical wall of the second cylindrical cavity, wherein the rotating motions of the first and second revolving vanes are coupled to one another in such a way that the edge of at least one of the first and second revolving vanes sweeps on respective circular cylindrical portions of the cylindrical walls of the respective cylindrical cavities at all instances, whereby a fluid moving through the first and second cylindrical cavities providing a flow passage in series results in a rotating motion of the revolving vanes and vice versa.
