Fluid characteristic sensing device
专利汇可以提供Fluid characteristic sensing device专利检索，专利查询，专利分析的服务。并且A device for sensing a characteristic, such as velocity or viscosity, of a fluid flowing through a flow conductor, the device having a housing connectable to the flow conductor and a tubular strain member having a longitudinal passage of the same internal diameter as the flow conductor disposed within the housing and constituting a section of the flow conductor, the strain member and the housing providing an annular chamber about the strain member, the fluid pressure of a fluid flowing through the flow conductor being communicated to the annular chamber by ports in the strain member or by a bypass conductor, and a plurality of strain gages spaced longitudinally of and bonded to the strain member and connected in a Wheatstone bridge circuit, the resistances of the strain gages at an upstream portion of the strain member varying as tension forces imposed on the upstream portion of the strain member and the resistances of strain gages at a downstream portion of the strain member varying as the compression forces imposed on the downstream portion by fluid flowing therethrough. The Wheatstone bridge provides an output voltage or signal which varies in accordance with the velocity of flow of the fluid through the strain member if the velocity of flow may vary and thus acts as a flow meter, or which varies in accordance with the viscosity of the fluid flowing through the strain member if the velocity of the fluid is constant and its viscosity may vary. The sensing device may also include means for sensing the temperature of the fluid to provide an output signal to a computer to which the output of the Wheatstone bridge is also transmitted so that the computer may provide an output signal, which is indicative of a certain characteristic of the fluid flowing therethrough, to a controlled device, such as a transducer, electrically operable valve, recorder and the like.，下面是Fluid characteristic sensing device专利的具体信息内容。
